X drive board fuse is blown. Need help to diagnose the problem. Are other boards like the SMPS the actual problem. I have the repair manual and volt meter but need guidance to narrow down the troubleshooting. Any help greatly appreciated.

    Just look into troubleshooting to any model Samsung Plasma TV. Almost all plasma TVs will have same configurations in circuit boards.

It's not the x main. 90% of the time it's a y buffer that goes out. It's usually the top buffer. 3/4 of the time the buffer takes out the y main board too. You cannot just replace the y-main or buffer because it will just burn out the other within seconds. Also about 1/4 of the time it'll take out the top transformer on the power supply too. The solution? First disconnect the power to the y main board. turn on the television and check the voltages coming off of it. Careful it's high voltage 208V! Remember it's DC too. Then disconnect the buffers from the y main board. You can try powering the y-main up to see if the little LED lights up. This does not indicate it's working though but it'll tell you if it is possible to fix. The fixes for these boards is only for electronics guys. It usually involves replacing 1-3 capacitors and 1-4 FET's. Since a bad buffer can take out a good y main in seconds it's usually recommended that one replace all 3 boards at the same time. It's a $250 fix. How do I know all this? I've now repaired 5 of these televisions. I owned one and spent close to 600 repairing it. I bought misc parts and broken sets online for months before I had 2 different repair guys walk me through the process of repairing them. I had so much cash tied up in parts that I bought 3 more dead sets and repaired them to justify all my spending. I've never had an x board fail. I've had EVERY top buffer fail. I've had all but 1 y-mains fail. and 1 lower buffer fail. I've also had the y buffer fry it's top chip, blow a capacitor and FET on the y-main, and fry the top transformer on the power supply before my eyes. It only took 5 seconds. Replacement of the 3 y boards will almost always fix the sound but no picture problem. Hope this helps!

SOURCE: Top half of screen going black.

I've seen this or something similar to this problem on an old lcd screen. The bulb haden't burned out but the system was no longer getting proper 5 volts to the processor chip that processed the image. I ended up desoldering the voltage regulator and soldering a new regulator in it's place it was one with the same amperage so I put a heatsink on it to reduce the chance of another failure.

I had the same problem and had the TV serviced and found that the y board was blown $350 total. The repair guy explained that the board has a hot transister underneath that slowly leaked onto the board, but says that they can not get Samsung to admit to the problem. Works fine now but only have a 90 day warrenty on the parts.

I doubt that moisture damaged the SMPS bd.
There are many circuit boards in your set and it will take a trained samsung tech to find the problem.

Hello, When I turn on my TV the screen does not come on but I hear sound. Can you please advise me on what I should do? Thank you in advance.


Hi tlc19732001,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing 24vdc coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the 24vdc is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hello! Unfortunately samsungs have a weakness in their driver boards, particularly the Ysustain video driver. This needs looking at by an experienced engineer, who will be able to diagnose this swiftly, and hopefully fairly cheaply. I have personally repaired over a dozen samsungs with this problem, and prices for parts without service range from 50 off the net , to 200 from main dealer. These are good sets, its a shame this problem is seen time and again.

My Samsung FPT5084 50 in. HDTV Plasma Television was working fine and now it won't power up when I try to turn it on. Is it possibly a blown fuse.


It's probably a blown fuse on the power supply circuit board, or if it has a circuit breaker maybe it can be reset.

No picture on Pioneer plasma


first of all check out the fuse that mostly get blowned out in this problems.if the fuse is perfect then it could be the faulty capacitor issue check out on the main board with the help of the multimeter and replace the faulty ones and it should work properly.

Check the fuses on the boards. If you can find the blown fuse then just replace that board. You can order parts from Samsung. The cost of each board is about $250 - $350. Or just drop your tv to Samsung authrized service centre, the shop will repair your tv with additional labour, depending on different shops.
