I had the same problem and opted to take the board out and replace the caps. They were all the same capacitance. Cost me $6.61 for 10 new caps (needed 9, 10 was cheaper). If you can solder, watch the capacitor videos on YouTube and give it a go.
There is a replacement for the original. You can try

Good luck

guessing may or may not help---if the power board had bad caps you may have missed one that looks good and is not OR some other part on the board may be bad--my instinct in this case would be to consider replacement of the power board first if you cannot confirm every single voltage is coming out of it.

My lg plasma 50pc1dra-ua tv will not turn on . it looks like it wants to turn on but never does. what can I do.

Open the back panel. have a look at the power supply components. Look for abnormal component shapes. i have found bulged capacitors which cause this problem.

Please consult a professional technician, if you are a novice in this field.

All the best

4 year old 50PC1DRA LG Plasma tv. TV would come on after several tries, now will not turn on at all. Just clicks. From what I read here, could be power supple? Is a 4 year old TV worth putting that...

It's the capacitors on the power supply, it's a common problem, either buy a capacitor repair kit (yes they make them) and have a TV tech solder them on, or buy a new power supply board (about $200) and remove and replace it yourself (it's that easy)

Why are we having trouble turning our plasma on it can take up to 10 attempts at times ,it pops aswell.

It's the capacitors on the power supply, either buy a new pcb board or buy the capacitors and have somebody solder them in. You can buy the new set on ebay UK for about 20 pounds.

Model #50PC1DRA no picture but we have sound we replaced the zsus board and main logic main board and still no picture


Thanks for using FixYa. As you have already replaced the Z-sus and the main logic board then the issue seems to be with the Y-main and/or Y-sus board. You’ll need to take the back off and check for any blown/bulged capacitors that might have gone bad and causing this issue. Please do accept the solution if the issue is resolved or post a comment for further assistance.
