RCA TruFlat 27V412T Chassis model M134C

I have the problem TV turns on and off by itself but I cant find a solution I saw someone already tried replacing the Main Circuit Board, Flyback and Eprom Im not sure but I was wondering if the problem could be the picture tube cause its causing the problem of too much voltage in the picture tube the output reading Im getting is 224V and the schematics reads that Im suppose to have 200V how could I reduce this voltage I already replace the capacitor and the highvoltage is still at 224V please let me know a solution Thank you

Greetings,

Turn the TV OFF
Remove the batteries from the remote
Turn ON the TV

If the issue still persists, check the channel-changer buttons on the TV

The microprocessor ic is breaking down or the pad switches behind the buttons on the front of the set, "one or two are bad" disable the front panel by unplugging from main board, if problem goes away use remote to control set.

Valerie,
That is a M134C chassis - one of the most inexpensive (throw-away) chassis ever built and the so-called v-chip is actaully a function of the micro, short for micro controller Ic. It would be less expensive to replace the entire board, RCA p/n# 268733 which is around $70.00 bucks plus shipping, than to replace just the micro.
You can find them available at Vance Baldwin... Just login as guest and enter thr RCA part number above and order it there.
Putting in an entire chassis is a plug-n-play repair...
Hope this helps.
Bill

This sounds like something best handled by an experienced tech since the fix involves extreemly high voltages nearby,
If you have a very good knowledge of the inner workings of tv's then ask for more information.
