No picture When I turn on my t.v. there is no picture but I hear sound. It is the fuzzy static sound. The power indicator light is on a well.

Check the lamps connectors on the backlight inverter board make sure they are not loose. You may be ahving failing inverter board itself.

Your TVs tuner tuned a little off frequency. It could be as simple as having cable box on where you have good picture but fuzzy sound, use the TVs remote to change the channel and then change it back to proper channel. If that doesn't fix you may have wrong tuning type selected in channel set up menu.

Can you hear any audio? Look behind the TV, you should see some light emitted from a grill back there. If you hear audio and it appears you can change channels and what not, you lost at the very least your back light, which can be replaced , or worse the power supply to the back light which will cost you a bit more than the already expensive backlight.

Chirping sound is coming from coil on right side behind FBT, resolder then use Glue gun to glue on top of coil LL037,Make sure high voltage wire from FBT to Trippler is in Good this is what maybe causeing lines and fuzzy picture.Also make sure solder on all pinns of FBT are good.

sounds like a splitter problem try replacing splitters

what are the indicator leds on the front doing? if all 3 leds are blinking then it's probably the color wheel ,lamp or the dmd board, if you turn it on and it goes through a series of shut downs then the leds blink, it's probably the lamp or dmd board.

The half picture is a verticale problem. This is difficult to repair. Send to a repair shop.

Its possibly a defective vertical output IC as that can cause the picture tubes to blank out and volume will audio will remain.
