Hello,
I have a 42pq30 LG plasma television that will not turn on. When it is plugged in and I press the power button, the red indicator light in the front comes on. I also hear a buzzing noise coming from the power supply, but nothing else happens.
After doing some research, I replaced the power supply. After trying to turn it on with the new power supply, I get the same symptoms - red indicator light and a buzzing power supply.
Any ideas?
Thanks!
I got a new power bored an it did not work an stell will not come on
Hello,
Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
if otherwise the power supply board is faulty you can try websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
Hope this helps
