Question about Standard (CRT) Televisions
I HAVE A 32INCH SONY TRINITRON TV THAT WHEN I TURN ON THE SOUND WORKS BUT THE PICTURE WONT. THE RED POWER/STAND BY/TIMER FLASHES.
Red LED flashes probably five times.
You have not mentioned the model no, so I have to guess it is few years old model.eg FE2 chssis or similar.
Most common reason, R618 270k ohms in power section has gone high.
Second, screen voltage control is slightly misaligned.
Third, high value resistors on tube base, normally two connected to screen voltage control pot have gone high.
You need to have some knowledge , a multi meter and soldering iron and know safety procedures before trying yourself.
