SOURCE: I have a 40" Samsung

That is a very bad situation there. It's definitely a hardware problem, but the fact that you sometimes get a picture is very strange. Everything points to a failing power supply / board in the TV but the screen coming on would go against that.. However it very well could be power supply problems, and that the power supply is just flaky and failing, working a small percentage of the time at high enough output to get the screen on, but not high enough to not get it on all the time...

However it's difficult to say with certainty that this is the case. Do you have the equipment and knowledge to test the voltage on the power supply outputs, inside the TV?

Let me know, it may need to be repaired by someone in person...

The buzz is the power supply attempting to power the set. The click is the unit shutting down. Can you pleae post the make and model as well as whether or not the standby light is blinking? With that info we should be able to give you some options.

Main power problem-i guess

Could be many things related to power. Sounds to me like a short though with that tzack sound you describe. How deep are you looking to get here or just looking for a major board to replace?

No picture or sound

Check the input, make sure you have audio and video coming in. Also verify that you have the TV set on the right input.

Can't locate correct tail light. All those shown are incorrect.

i assume you are ordering a taillamp for a '03? check your door jamb for a manufacture date sticker, you may have a late model '03 that has some '04 parts on it.

I have the same problem with mine. i,m pretty sure that it is the built in surge protector is bad. Try unplugging the tv for 30 seconds then plug it back in and turn it on. If your surge protector has not completely gone bad this might work a few times. mine won't turn on at all anymore.
