Sounds like you have an internal fault (probably on the power supply board) This is the board that generates the various voltages for the various parts of the tv circuitry. The best is to take it to reputable tv repairer(just what you didnt want to hear hey)

Have an older Toshiba theaterview TV, when turn on, we have no picture, no sound, just black screen and blinking red light that just continuously blinks.


Theaterview suggests a rear projection--in that case it most likely is in the convergence circuit--unsolder chips (convergence) and see if set turns on.

Some of their regular TV sets (picture tube) if the light is just blinking means the same thing=shutdown because of a short/problem but a model number would tell me which you have.

Check fuses on Power Supply board (F850, F851, F852) and all other fuses. Replace blown fuses (will need an ohm meter to check fuses). I would also replace the two convergence amps (STK392-110's on the signal board, the big black ICs on the two heat sinks). This worked for me.

Power light blinks and no picture


No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture. Sometimes no picture at all. Sometimes picture OK for longer. Sound unaffected.
Faulty joints on CRT pcb. Cracked solder joints at tube socket connections on CRT circuit board. Caused variable supply to CRT heaters. Resolder all socket pins to pcb.

3) Replace convergence IC's ( possibly damaged)
