This is a very common problem with model. This problem is your Z sus Board. NOT your power supply, or Y sus board. There is a pair of Diode that goes bad. Your only solution is to change your Z sus Board. Part Number 6871QZH036B average cost $237.00

SOURCE: LG 50inch Plasma received loud sound then went black

My friend's LG 50" plasma tv has the same problem and it cannot light up. The picture and sound are working fine. But the brightness is too low. It is purchased 2006 too and out of warranty. So I opeend up and found 9 capacitors 3300uF 10V on the power module at the middle of TV are popped. I am planing to replace all of them. They are available at digikey.com. I think this model's power module has design flaw. The cap rating may to low. 10V? Stay tune to see what happen after I change the all the caps.

SOURCE: lg model 42pm4m plasma monitor won't turn on, red

Does the tv make a clicking noise like its trying to turn on before the tv goes into standby and the LED starts flashing? I suspect this is due to a shorted component, most likely to be in the 5V(switching) line and just want to be a bit certain before we start testing the power supply.

Lg 42 plasma - loud bang/spark smelly smoke and small flame inside.


It is a short circuit caused by some components and/or power capacitors. This may need assessment by a qualified service technician.

I have a Sony KD-34XBR960 and the standby light blinks twice and makes a click noise and a bang sounds off in the back of the TV and then it repeats its self , the TV does not turn on .


  1. Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

My LG TV red light won't turn on. although the plug fuse and the remote OK


Try manually pressing the power/standby button on the tv (side or bottom) the red light should appear, most modern tv's will turn on simply by pressing the channel up or down on the tv itself.. But unfortunately in most cases, this seems to be an internal surge and needs a professional to inspect..

My LG 32LD320 won't turn on. I have no standby light and have even tried changing the fuse. Help please!


If total dead best way is to follow the AC voltage from power cord inside the set to see where voltage is lost.

Also , were you having any problems having to turn set on several times to get it on?

I've had several power cuts lately , now my tv is


Hello rogerstanila,
if you have tried unplugging it for a while and if there is still no change then it could be your main board. Unfortunately to fix this could be costly. See if you can find a repair tech that will do a diagnosis for free. But there has quite a bit of problem LG tv's being stuck on standby especially the LCD tv's, Other than this there is not much you can, maybe changing the battery of the remote and just keep trying to click on and off. If it is plugged into a cable box, try unplugging all of that for a while. Leaving it unplugged for a day won't hurt. If nothing else then it could be your main board. You could replace it but as I said before it could you couple hundred dollars. Hope this some what helps.

Hello, My tv is about 5yrs old.We heard a loud


Hi,
You need to replace Y main board & buffer, which will cost you around $600-700. Since the TV is five years it will be better to go with new, and it won't be worth enough to spend $700 for old TV.

Hope this helps.
