You have bad capacitors on the Power Supply PCB. There's probably like 9 of them bad, if memory serves me correctly. I have a tutorial published on a Samsung repair involving capacitors. It's not identical, but the solution is similar. I think in the case of your TV, you'll be looking for 3300uF caps with swollen tops. If after looking over the tutorial you decide this isn't for you, get the TV to a repair shop. I highly recommend you stop watching it and unplug it until you get this fixed. I hope this was of some assistance.

My LG 42Px5D Plasma; when I turn it on, it is blinking for a couple of minutes, then it is normal again. It started happening only a couple of months ago. What's wrong? Thanks


THERE WILL BE A CAPACITOR GONE FAULTY IN THE POWER SUPPLY,,

IF U OPEN UP THE BACK LOOK ON THE TOP OF THE CYLINDER TYPE CAPACITORS THAT STAND UP THE ALLOY ON TOP SHOULD BE FLAT ON THEM ALL ... IF ONE IS BULGING AND TOP HAS BURST OR READY 2 BUST THEN REPLACE WITH A SOLDER IRON,, THIS WILL FIX THE SLOW START UP AS THE CAPS NEEDING TO GET WARM TO FIRE UP THE PSU,,

This is a common problem with any make Plasma, chances are the Y sustain module has gone bad. Sometimes it takes 3 separate modules by recommendation from mfg's to be replaced at the same time. Let me know what you have done with this issue please?

Green Screen - LG 42PX5D


hello, seems to be panel trouble, plasma and lcd main panels are not fixable, the color green isnt a good sign or it is a symptom of the panel being bad,
i know its a bad diagnosis but this is true with this color on a panel.
if it is a worth while set and you want to restore it theres few options one is replacement trough your waranty

the another is having the screen replaced by a service center this is to costly and rarely done by them they would advise you to get another set. at a retail price a screen replacement is as much or even more than the tv itself.

finally you may search online listings for a servicable tv same model and exchange the parts .
the third option is the best if your waranty is expired.

good luck hope this helps

happy holidays.

No digital picture


Try and reprogram all channels in the tv. Goto menu and use the auto program function to do this and see what happens. If this does not fix it then you will need to send to a repiar shop. The main pcb is most likly bad.

42" lg plasma tv


The first thing is to take out the batteries from the remote when the problem acts up. If this fixes it, replace the remote. If not, go to the front of the tv and find all the buttons that are on the tv. Start by pushing all of the buttons one at a time. They should all feel the same and sound the same when you push them. If one of them does not, then the buttons are the problem. If they are good, take to a repair shop. The main control board is bad.

lg plasma tv is not for a novice to play with. the three main circuit boards are control. y and z sustain and they are not repairable
find a shop that can replace the defective one for you.
