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.
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.

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.
Same problem here. Blinking power light, no sound or picture.
