SOURCE: my ASTAR 32 inch has no picture or sound for 10

Hi,

You have an AC resistance problem on the interface board. Passive components such as silver mica and electrolytic capacitors are not charging and discharging properly. This causes a delay or disruption in the start-up process. Byte signals are weak and intermittent due to other thermal components failing such as 'diodes, smd mosfets,...etc...''' Believe it or not this happens from manufacturers using 'inferior-grade' circuit components that fail under considerable load conditions. By replacing a few parts with better quality parts will solve this issue for you. To replace these parts requires removing the back cover and using some test equipment. If you can get someone who is technically proficient I can e-mail them instructions on how to fix this problem on the circuit board.

Let me know if you want to follow up on this...

SOURCE: sound but no picture

Most likely you have an inverter problem. The inverter powers the backlights so that the picture can be seen. You can try holding a flashlight close to the front of the screen in a dark room and if you can see any trace of a picture, the backlights are not lit. This can be a pretty hot circuit to work with. Have a shop check it out for you. Thanks for using fixya.

SOURCE: tv keeps turning on and off

You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.

SOURCE: my LG HD tv screen suddenly went green. sound is

Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.

Try connecting the Bluray player directly to your projector and verify if you have the same issue. If you do not have an issue, your switch is causing the picture to freeze.

If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel

This is typical of dried up old capacitors. The problem can be cured by keeping the TV on for days. The moisture in the air will be the cure for the dried up capacitor. It will be good as new if you use more frequently.
