Question about Toshiba CZ36V51 36" TV

1 Answer

Power light blinks and no picture

Occasionally when turning on my TV the red power light will blink and there will be sound but no picture. Then it will stop blinking and the picture will be perfect. It happens more often when you turn the tv on more then once a day or if I used the remote to shut it off.

    I began experiencing the same problem just yesteday. Sound and pic returned later in the day and worked fine for almost 4 hours. However, the following morning the problem returned after being on for only 5 minutes. Frustrating that this would happen with a named brand television, which I only purchased 5 years ago.

    I have no picture and no sound. The red power light continues to blink. I have unplugged the TV but this doesn't resolve the problem.

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.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Sony LCD television will not power on.


I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
