TOUGH DOG: RCA TV model 27V412T, chassis M134C turns off, then on by itself

[Brad]

Hi,

PLEASE READ my original post below.

I have a RCA TV model 27V412T, chassis M134C (mfg 01/06) back in my shop,
which I thought I repaired after I replace the remote receiver. The TV worked
fine for a couple days, then it started all over again. I removed the remote
receiver and put a 10K from +5 to the remote's output line, but the TV
still turns on, then off by itself. I checked for leakage on the panel button
switches. Also I found out, before I removed the remote receiver, the TV
would not respond to remote commands, and the scope showed a good
output signal from the remote receiver. Note: The TV did respond to remote
commands when I first started working on it. I checked the +5V and scoped it
for noise.

I found info on the Web about a setting in the service menu that can cause
this problem, via "7", OPTM2 should be at "00", but this setting is correct
("00").

Did you have a similar problem with this or similar a model TV?

Thanks in advance, Brad

Yes. Set would turn itself on/off at random, sometimes the front panel
controls would work, other times they wouldnt,
erratic operation using the remote.
Some one had gotten a bit wild with the Windex, which had run down the
screen and dripped on the control panel and switches. Replaced the control
panel with one out of a junker, not a bit more trouble out of the set, no
customer return.
