Unplug the set for about 30 minutes. This will reset the unit hopefully. Thanks for using fixya.

dirty CRT socket or leaked capacitor or disoldered resistors .You need to see a qualified technician.

Bad LCD controller, see sample here (note, I removed the cover off the board so you can see it): http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/

Be real careful when you remove the back cover, the side switch assembly is attached to the back cover, so do not yank it too hard!

Resolder pinns on FBT flyback transfomer and on tuners.

Hello arunaik_6,

This looks as if a component has become thermally sensitive. The best way to find this is to use component cooling spray. It looks as if the problem is localized to the tuner section. Take the back off of the TV and turn the TV on, wait until the problem occurs and lightly spray the tuner section with the component cooling spray watch for any reaction, then if this does not work spray the Microprocessor and the LVDS section and watch for a reaction. The set should go back to normal when it does that section is the problem, try to localize the problem to one component. Then replace that component.

I hope this helps,

Thank you,

I would call LG and have them assist you with a repair. The most helpful number is 877-543-8325. It doesn't matter if you are in or out of warranty.

I sorry to say I think you have a component failing that is related to heat. 15 years is a long time and if the TV was used in hpot conditions over the years it may well be the proble, or it's just old.

Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider

i tried unplugging mine when the picture went out. i left it unplugged for about 10 to 15 minutes. still no picture
