Hello catapracht, It looks like you shutdown circuit is turning the TV off due to a problem in the HV section. What you are seen is possibly a green cathode short and some blooming occuring. These will caused increased anode voltage and trigger the shutdown circuit. At this point I would not suggest blind swapping of parts but rather you find a repair shop on FixYa.com, or find a shop close to you to have this problem dealt with. Because these are dangerous voltages you will be dealing with and without the training and knowledge of TV repair it would not be adviseable to do these repairs yourself. However you can be of assistance in have this information ready for the repair person. Thank you, I hope this helps. Shuttle83

When I power up, 5 seconds later this back projector TV turns itself off
t does sound like a bulb problem, either its over heating and shutting off to protect itself, or its already shot. Give a TV repair shop a call and see if they can give you an approximate price, then decide to ditch or repair it.

Problem with RCA TV Model 27F634T
You almost certainly have a bad picture tube. The green screen was from one of the elements inside shorting out. The static sound you're hearing is the high voltage arcing out through the end of the picture tube to other parts inside the set. It's more economical to buy a new TV than to repair this one.

Sorry to have such good news, but this is one of the ways a picture tube can go bad, and it happens quite often.

TV has sound but no picture
It is possible one of the internal fuses blew out.
It could be a bad horizontal outut transistor.
It could be a bad secondary of the power supply went bad
And many other things.
If it's just a fuse, it won't cost much, but a lot of them do not look like you would expect a fuse to look like.It might be a little yellow, green, or gray rectangualar box shaped part. :D

TV WENT OFF BY ITSSELF
This TV has reached the end of its (short) life. Needs to be replaced.

You can try looking at what kind of TV it is, what model, and look at the manufacturer's web site, check for the manual, look up what it means when the green light flashes. Might be a code that means something but I think the TV is dead.

TV shutting off by itself
The plasma panels operate on 170VDC and 60VDC, Sound like the 170VDC from the power supply is low or dropping low. You need a tech to look at it, the voltage sources are marked on the board and the adjustment is labeled. Typically a component such as a regulator or capacitor is leaking to cause the voltage to drop.

TV will not come on
How old is this TV?
Sounds like it has high voltage failure.
(If you hold your hand on the screen when you try and turn it on, do you feel the static? )
Unless the set is over 10 years old, I would overhaul the high voltage circuit. Should cost under $200 at a shop.

Sounds like its going into auto protect shutdown. Try holding the imputand menu bottons in together for 5 seconds and see if the green light blinks out a series of blinks. If so notice what they are, should be a 2 digit code if its going into shut down. If not its a power supply issue. Also you can look the boards over for evidence of CRT fluid leaking on the boards, I have seen this happen alot to the VS models it causes corrosion of the components and you will experience no start up condition like the one your describing.
