When your tv turns on by it self you prob have the alarm set. For the tv to turn like a clock would go off when u need to get up. You need to check the the sleep/ wake up timer to see if it is set.

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...
,
WITHOUT GETTING ELECTROCUTED
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.

anyhow

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 TV Turns itself on and off, changes channel and volume by itself. Frquency of off and on is as many as 20 times in 5 minutes. I even removed the batteries from the remote to make sure it wasn't...


I had the same problem. Got it to stay on by unplugging the front button pc board while I researched the issue. It seems that the switches on said pc board begin to "leak resistance" and cause all kinds of problems like on/off, color maxes out, as well as other crazy stuff. After calling RCA and getting no help I decided to remove those seven micro-switches off of the board and, wouldn't you know! Everything is ok with the exception of not being able to controll the tv from the tv itself. Small sacrifice for a free fix. All tv functions work from the remote. Again, a small sacrifice for a free fix! Just be careful when poking around inside, high-voltage and stuff.

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.
