MY LG TV MODEL NO 42LG80FR LATE START


I had a 42" LG that began taking longer and longer to power up and finally would not come on at all. I opened it up and found several bulging capacitors on the power supply board. I found a company online that sold a replacement kit of the 10 power supply board capacitors for $18. Installed the new caps and the set has been working fine for two years. You do need to be careful since there are dangerous voltage levels inside of the case and you do need to know how to solder. If you have any doubts, find someone who knows what they are doing.

the tv shuts shuts off by itself and wont come back on until next day, do you know what causes this


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

TDP-S8


The main problem is the power supply. In detail, the output capacitor of the power supply causes the problem. I guess, Toshiba or Lite ON didn't consider the aging effect of the output capacitor. You should replace the output capacitor to fix the problem. (In some sites, they recommend to replace the power supply, but don't do that. The new power supply costs over $200 and the capacitor will be less than 50cents.) If you disassemble TDP-S8, in the power supply, you can find the electrolytic capacitor 3300uF/10V. You should replace this with any electrolytic capacitor with the range of 2000uF~4000uF/10~16V. You can download the service manual from some websites (I've paid $5 for this) then you can disassemble the projector. Of course, you need to do soldering to replace the capacitor. I've fixed this problem yesterday and it took about 4 hours for me. Good Luck~~!!
