This tv has some weird problems. Tv will power up but it wont stay on one channel it just keep running scanning all the channels. sometimes i wil press the menu button and it would cut off, other times i would press the volume button and it power on/off. I have seen retrace lines comming on and off after which it would go off.
I am getting B+, also the 25 volts and the 200v. up to the crt. board. i have change some caps around the vertical l/c eventhough i am getting the 25 volts out.
Dont have a schem. any tips would do.

Replace all of the front panel swithches. Sounds like they have been
contaminated

Have had RCA's in past with resistance in pushbotton switchs. Suggest removing one at a time and check using remote. One of the units had three bad and caused intermittent problems until replaced.

Mario, it sounds like the "windex syndrome". Remove all the switches and try
the remote. my bet is also contaminated tact switches / switches.
