Turn on relay is operating and tube starts to charge, but then the relay turns off and on and off again by itself. This all takes about 10 seconds. Picture and sound do not come on.

Why is it erratic starting and only displays half of the picture?

problems with crts are difficult to diagnose. this could be due to a failing tube or faulty electron gun...It is probably best to call in a technician to take a look.

I have a 27 inches RCA TV (model:27R410T) , Firstable when i turn the tv on ,it works fine but just for about 2 minutes , after that video has gone , no video only audio ,and start changing channels...

It maybe some semiconductor IC got hot, need service or repair. It may repair itself if you leave it on standby for a month(at operating temprature a week)? This is low tempeature(the lower the temperature the longer the time) annealing or moisture curing technology, used by Nasa on transistor failure in satellites, or long range unmanned vehicles. You can always repair the unit later.

Why does my RCA model# 27V412T turn on and off by itself? It's does not stay on long enough for me to reprogram the remote.

Hi There,
Sounds like your Startup Relay is intermittent. Contacts are closing (tv on) then dropping out (tv off). Worn or burned contacts do not make a good connection when they close and start to burn and overheat causing the contacts to open. When they cool down they may make contact again for a very short period. You need to replace the Start up relay. I hope this helps and thank you for using FixYa!

No picture

I would pull the cover off to see if the tube and the board on the CRT are not damaged. If it looks ok, turn set on and observe if there is any activity visible at the neck of the CRT (light). Wehn a set with a large tube starts-up, it wil make a fuzzt crackle noise fro the high voltage charge in the tube. If non of this is happening, check main board for cracks. Unit is probably salvageable for point to point solder job, but as far aspart replacement for HV power supply, I would not do it. It is not cost effective.

YOU might have a bad relay or a bad solder connection in the relay control circuit. Sounds like a bad solder joint. Stargazer

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer

Tv was working fine...then shut itself off.

there is no reset button on any tvs that stop in 1980s when they no longer used tubes in chassis,s now the only tube is your picture tube. you probly have a shorted hori out put transistor.
