When a Samsung TV shows a standby light but fails to power on, the issue often traces back to a faulty power supply board. As the central processing unit within Samsung smart TVs, the power board distributes electricity to all other components. Replacing this printed circuit board is key to reviving a dead Samsung TV.
While some DIYers find power board replacement daunting, it’s achievable for intermediate home technicians willing to learn. Costs vary widely based on the TV model, starting around $100 for basic sets but going up to $1000 or more for premium versions. Multiple factors like TV size, features, age, and availability of used boards influence expenses.
In this detailed guide, I will discuss the key considerations that impact costs for replacing Samsung TV power boards. I will also provide examples and price breakdowns spanning low-end to high-end Samsung TV power board repairs.
Factors That Influence Replacement Cost
If your Samsung TV troubleshooting proves that the power board itself is no longer functioning, replacement provides the repair. Several variables affect what you will pay:
TV Model Impacts Price
Each Samsung TV model utilizes a custom power board wired to match components within that chassis. Main boards for newer 4K QLED TVs with elaborate internals unsurprisingly cost much more than boards for decade-old 1080p sets. Secondly, the volume of production means popular high-sales models have better replacement part availability.
Where You Source the Replacement Board
Genuine Samsung service center parts ring up the highest invoices but provide guaranteed quality and compatibility. Third-party electronic repair part vendors offer discounted boards, but sometimes a possibility of compatibility issues. DIY sourcing takes the most effort but promises the best savings potential.
Installation – DIY vs Technician Labor
Replacing a TV power board yourself brings satisfaction and saves on labor charges, but requires skill working with electronics and TV disassembly. Hiring a specialist brings convenience but tacks on hourly rates ranging from $50-$150 in most metro regions.
With the pillars affecting expenses covered, let’s explore detailed power board replacement cost scenarios across the Samsung TV product ecosystem – from economy entry levels to luxe QLEDs.
Cost to Replace Power Board in Samsung Entry/Mid-Range TVs
Samsung offers a vast lineup spanning entry-level HD TVs to impressive 8K Neo QLEDs showcasing the best display technologies. Let’s start estimating power board replacement costs for lower-end to mid-range Samsung sets between ~32″ to 65″ in size.
Samsung Entry & HD TV Example – UN32EH4003F 1080p (2012 era)
Since it originally retailed at under $300, restoring this common older Samsung 32″ 1080p LCD TV proves cheaper than ditching for a new equally-sized unit if repairs are self-managed.
To replace the power board, also referenced by part # BN44-00474A on this model, typical costs are:
BN44-00474A Replacement Board
- Samsung parts distributor – $86
- Third-party eBay seller – $39
- Generic compatible board – $27
Adding $40-$100 for 1-2 hours of labor brings this repair to $120-$160 total. Compared to stepping up to even a basic 2023 model 32″ Samsung 720p TV averaging $180+ brand new.
Of course, dumping any more repair money into an aging set with limited features is debatable versus saving towards the latest value-packed smart TV – but for those comfortable fixing their existing panel, it remains viable, especially considering the environmental impact.
Samsung 6-Series Example – UN65NU6900B 65″ 4K UHD (2018 era)
Stepping up to a popular 65″ Samsung 4K LED TV like the NU6900 series shows how increased display size/resolution in turn ramps up power board replacement costs.
BN44-01259A Replacement Board
- Samsung authorized part – $218
- ShopJimmy third party – $89
- Compatible generic – $51
When adding the estimated 1-hour labor at ~$75 per hour, total fixed costs come to $320 using genuine Samsung parts but could be as little as $150 with DIY installation and third-party board. Defective backlight repairs might run higher but replacing a bad power board makes financial sense for owners of this ~$800 4K TV even just 5 years into its lifespan.
Determining If Your TV’s Power Board Needs Replacement
Before exploring replacement power board sourcing and pricing, let’s ensure your Samsung TV does indeed have a faulty board that requires swap out.
Troubleshooting the Issue
Symptoms of a failing or dead power board include the TV displaying no picture or sound, failing to turn on fully from standby mode, or power cycling on and off repetitively. Often the standby LED will still light up even with a bad board.
Start troubleshooting by checking,
Wall power outlet – Confirm the outlet is functional by plugging in another device. A reset outlet switch is available too.
Power cord – Try disconnecting and reconnecting the TV power cable, or swap in another power cord if possible to rule out cord issues.
Input switches – Cycle TV external input channels and sources press the power button multiple times attempting to force past any freezing.
If power problems persist through the troubleshooting steps above, it likely indicates an internal TV hardware problem – commonly traced back to failures on the power supply board.
Diagnosing a Faulty Power Board
Before spending money to replace your TV’s power board, it’s wise to diagnose further and confirm the legitimacy of the fault. Here are the steps to validate:
Step 1: Visually inspect
Open up the rear TV cover and examine the board for any damaged, burnt-out, or abnormally hot components. This can verify the failure.
Step 2: Check voltages
Use a multimeter to check if expected standby voltages around 5V are present on board. No output indicates an issue.
Step 3: Swap boards
If you have another Samsung TV with the same board, swap temporarily to test if the issue follows the board or stays with the original TV.
After physical inspection and voltage testing, if another known good board also fails to resolve the no power/no picture symptoms in your set, it’s best to then re-evaluate other internal components before declaring the board at fault and seeking a replacement.
Cost to Replace Main Board in Samsung QLED TV Models
Now let’s explore the repair value of flagship Samsung Quantum Dot LED televisions which range from $1000 to over $5000 at retail when initially purchased.
Mid-Range QLED Example – QN65Q60TAFXZA 65″ 4K QLED (2019)
This well-reviewed 65″ 4K Ultra HD Quantum Dot LED TV combines Samsung’s best display technologies with smart features, originally retailing around $1700.
To replace the complex main power board within (part # BN96-37470B) once the TV is out of warranty:
- Samsung parts – $348
- ShopJimmy – $268
- Compatible version – $197
With professional installation estimated at around $150 for ~2 hours – this brings totals to $500 using Samsung part or as little as $350 with third-party board and DIY skills. Likely worth it to save a $1700 investment, but overall repairs approaching or exceeding half the original purchase price lessen the value proposition.
High-End 8K QLED Example – QN85Q950TSFXZA 85” 8K QLED (2021)
Finally, evaluating repair viability for lofty premium tier 2021 model 85″ Samsung Neo QLED 8K smart TVs retailing originally at $10,000 shows the upper limits of power board replacement costs.
Genuine Samsung part # BN96-42956A rings in around $950 from authorized supply channels – making any repair pricing quickly hit four figures when including pro installation. At nearly 10% of the original purchase price with no guarantee against future failures, the economics become harder to justify compared to claim payout via extended warranty or simply reinvesting in the latest technology.
In rare situations where the budget allows for high-value repair components without consideration of new replacement costs, owners can maintain the functioning of beloved Samsung TVs. But for most average consumers, prices exceeding 20-30% of the original display expense make replacement more prudent.
Additional Charge Influencers
A few additional variables layer onto the base estimates provided above:
- Age and availability of replacement board add premiums for vintage TVs
- Specialist experience needed for deluxe models increases hourly rates
- Extra repairs like backlights raise costs further
Consider insurance/extended warranty ability to subsidize repairs or payout for replacement rather than sinking heavy money into older TVs. New panel technology progress also impacts value calculations.
TV Power Board Replacement DIY Considerations
For suitable models, namely mainstream HD or 4K LED sets, replacing a failed power board yourself can greatly minimize repair costs. However, below factors require consideration:
a) No guarantee/warranty protection
b) Troubleshooting complexity if the issue persists
c) Risk of component damage
Skills & Tools Needed
a) Electronic repair knowledge
b) ESD precautions
c) Inside-TV workspace
d) Soldering gear/materials may assist
Consult YouTube tutorials before attempting. Allow 2-4 hours for first-time repair.
If the hassle outweighs potential savings benefits, professional TV repair shops specializing in Samsung service may provide peace of mind, though costs inflate accordingly.
When to Cut Losses & Buy a New Samsung TV?
Repair feasibility ultimately depends on your budget, the value of the existing TV, DIY skill comfort levels, and technical constraints like repair part availability for dated models.
As displayed size, display resolution, and integrated smart platform age all escalate year to year – investing $400+ into a power board for a 1080p set from the last decade potentially wastes money sinking into inferior technology.
Like a used car requiring an engine rebuild, the repair costs themselves may approach 50-70% of a comparable new TV price. As this tipping point reaches mid-size 4K TV power board replacements, opting for new increasingly makes sense.
For owners of high-end Samsung QLED 4K and 8K HDR television models less than 3 years into the expected lifespan, repairs likely justify supporting continued usage before considering full replacement.
So, costs to replace a failed Samsung TV power supply board vary tremendously – ranging from as little as $100 for entry HD models when self-fixed, up to nearly $1000 or more when accounting for premium Original Equipment Manufacturer (OEM) parts and professional installations on deluxe Samsung Neo QLED offerings. The repair value depends greatly on the model, board source selection, DIY skill assessment, age/purchase timeframe, and failure probability comparisons against new TV investment.
Hopefully, this walkthrough of power board failure troubleshooting, replacement part sourcing, repair cost scenarios, comparisons to the new pricing, DIY considerations, and final advice will assist Samsung TV owners in determining the smartest path back-to-picture functionality.
