I have an LG plasma TV, model: 50PC1DRA. We had a

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.

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

Hello, not exactly sure what part you need to fix your tv. But, I have used a company named ShopJimmy.com in the past with great success. I included a link to your model page from their site. Hope that helps!

Depending on what made the power outage, your power supply might have got fried. It might be as simple as a few capacitors blowing or a little more serious. I would suggest taking it to a repair shop. A power supply replacement will run you about 200-250. If its just a few capacitors, should be around 100.
