TV keeps shutting off. It will stay on a few minutes when cold but then will shut off. When we turn it on again after its warm it shuts off and won't stay on. Could something in menu bar have been changed...

It looks like a power supply SMPS problem.

You have to replace the optical isolator in the SMPS feed back circuit. It is a 4 pin IC
Mostly this may be the problem. Take the help of the service personnel.

Unfortunately, the Power Supply has spat the dummy out. It is giving enough power to light the LED but not enough to run the set. To replace it will probably cost more than buying a new set. But ask around your local repairers for a price before you make any decisions...

My 32v434t television.

The TV was making the clicking noise and not turning on because an internal error was being detected.
Now things had got worse , and something had blown inside the TV.
The burning smell and high pitched noise is coming either from Flyback transformer or PSU board. Repair is a delicate matter and must be done by a technician.

Got an rca 32v434t, plugged in hooked up, and it

we would need more information:

has TV worked before
how many hours has TV been used

I have seen this 'ShutDown' on many failing monitors..

Typicaly the Power Supply circuit in your TV
have 'Over Current' detection\protection
and your 10 second is just about how long somthing is probly taking to either:

over current and shut down
or more specifically:

one or both things wrong with it:

bad electrolytic capacitors ( maybe )
but if it's a perfect picture for all 10 seconds then probobly some specific semiconductor or module is: 'Heating Up' then 'OverTemperature' and failing in a manner that causes an immediate overcurrent condition, shutting off the TV.

- give more information

- if capable of safely removing the back of the TV to allow for inspection...
by the high voltage that remains stored inside the tube, even after power has been removed !
then pop her open and have a look at
the PCB's ( circuit boards )

if somthing has been running hot and has led to this type of failure; then your circuit board will be discolored near the mounting of that device... You may even notice a burnt pcb smell at that area.


somtimes you can find these semiconductors or modules in catalogs or online ( OfCourse )

and yourself or sombody with sufficient knowledge of soldering and the
' Potentially Life Threatening Hazzardes '
that exist around CRT monitor repair....

... can go ahead ad replace the suspect part.

RCA 32V434T (32'') TV has no Red or Green pixels, only Blue

The color problems are caused by cracked/broken solder joints on the circuit that controls the display.  Usually this is located at the back of the tube on a small circuit board. Your description suggests that only the blue signal circuit is intact. I suggest these joints be resoldered for more strength.
It's a possibility that another IC senses this problem (or another one) and then shuts down the system.
Resolder those joints and see what happens.

Tv no pic or sound

If you hear the high voltage try to come up and set shuts down in 2 secs it could be your FBT also these sets have alot of poor connections chassis should be resolder.
