Toshiba 27af45 repeatedly turns itself off. Sometimes (usually) every few minutes, other times will stay on for hours. Works perfectly otherwise.


The fact that the television stays on for hours and other times turns in five minutes shows that your problem is intermitent .A defective component in the power supply is probaly causing the B plus voltage to go up.The TV can also have a dry joint which looks more likley i am curtain if you gave the TV a firm tap to the side when it come off it would come on back. Try it .

Toshiba Color TV Relay clicks slowly. TV does not come ON.


Electrolitic Capasitors in the power supply going or being bad will cause this. At some point a low value resister also will start to run hot or burn up. I believe it it a 16v 1500 uf cap near the relay. I would also replace any 10uf 160v caps in the powersupply too.
Hope this Helps,

Sansui tv shuts off by itself after being turned on.


the relay on the power board needs to be replaced; if you feel confident to do this:unplug the tv wait about a 1/2 hour then remove the tv's case carefully look for a small black or, brown box about 1/2" x 1" x 1/2" this relay should have a designation such as Rly 1 printed on the circuit board it must be unsoldered and, removed the numbers on the relay can be entered into a search engine to find a replacement

TV turns off by itself


Thus the line connected to a surge protector or some kind of line protector. This can be consider.

Or if this is a crt type tv. This could be a fault on high voltage section. Horizontal output transistor or flyback. But check also for loose connection/solder crack. That clicking sound may be the relay in action.

hope i give some correct input.

Toshiba cf32c50 tv will not turn on


This is a typical condition if the power supply has failed or a power-consuming circuit the supply services has exceeded a predetermined current draw. The relay you hear is preventing further damage or even fire.
You will need local tech help with this.

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