The replacement board could be defective. Your TV worked fine until there was a power loss so its time to troubleshoot to find out how the power loss affected the original board in theTV. There could have been a power surge.

Plasma LG 42PC1D just clicks when you power it on and will sometimes turn on after 30 -40 attemps


This sounds like you have a known issue with the power supply board. The power supply is seeing a problem (typically with the 5vdc) and will shut down the TV just after you try to turn it on.

If you keep trying to turn on the TV, eventually you will catch the 5vdc circuit working and the TV will work until you turn it off.

Soon, the power supply will fail to where the TV will not come back on.

The power supply is around $160 and up. I can find your part number if you give me the rest of the numbers after the model number (example "A.SUSLLJR").

Or, you can have someone in your area fix you TV.

Good luck. I hope my information has helped you.

Sony TV not turning on


Chances are the Power Supply failed because the Horizontal circuit failed. It would not be out of line if the repair cost ran 250.00 plus.
It is probably not worth fixing due to the age of the set.
Hope this helps,
