Tv goes a pinkish white flash and turns off after 5 minutes will keep repeating this after a break of 10 minutes and after 3 or 4 attempts the tv will then work as normal the rest of the evening?

If you have zagged lines there are 10 small surface mounted capacitors you will need to change on the HYper Board. This is not an easy repair so alot of folks simply replace the hyper board. You will need a service manual to take this set apart and to get the proper part number. If you have no TV repair experience or do not know how to solder, as the hyper board has sheild arounfd it, you should play it safe and call out a pro to assist you in this repair. Good Luck

I had same problem - no picture, but sound worked - LG 42PC3d - was two months past warranty, but LG agreed to fix it as a warranty call. Service guy was out within a week to replace the Z SUS(?) board. Works fine now. This must be a typical problem, as LG did fix it, even though the warranty had expired. Good luck.

I have read everything I can find on the net about this problem for Polaroid TLX 04240b TVs (most, like mine, bought from Wal-Mart on Black Friday after Thanksgiving). I thought I was on a hot lead when I changed a 220uF 450v capacitor, but I still had the same problem. I saw a short post from somewhere else on this Fixya web site (sometimes I can find it again and sometimes I have trouble locating it) that said someone flipped a tiny switch on their circuit board and the problem was gone. I did the same thing and my set has been working fine. They had said their set was on for over 8 hours two days in a row when they posted. The other night my daughter left our set on over night for 20 hours and the picture still was working great. If you look through the top of the set when the picture is on you can see some white light at several locations, when the screen goes blank the white lights go out and a red LED light can be seen. If you take off the plastic cover on the back (3 screws) and then take off the metal cover (3 screws) this red LED light is on the upper circuit board in the lower left corner. Just a little to the right of the LED light is a small switch block that has 4 tiny white switches. I turned my set off and took the bottom switch (#4 and had the letters BURN by it) to the right "ON" position, turned the set back on and, so far so good. PLEASE NOTE!!! I know almost nothing about how transistor circuits work. I have no idea what the switches do or what long term effect this might have on the set. The set was only good as a paper weight before so even if this only fixes the set for a short time it was at least worth a try for me. Does anyone know what those switches are supposed to be for????
