My tv blinks from black screen to picture

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

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.

The light is blinking a code. The code will be a series of blinks, a pause and the blinks again. Phone Sony service and give them this code. They will be able to advise you as to the problem.

call service .........or manufacturer and and ask for service advise........if ur set is under warren tie it will be fixed without charge

your tv is on the blink.

remove the back panel of set
on the crt pcb board you will find a wite or black pot.
turn it up or down while set is on this is the G@ voltage ajustment.
you might get 3 monts to a year of extra life from your pictor tube by doing this.

My sony tv 1993 model Have no picture, but do have sound. Screen is black. Any ideas?

sorry but u have a bad picture tube , time for a new tv

turn up your master screen control on flyback transformer. if when sceen gos black ,the timer light will be blinking. this means your picture tube is week. by turning up the screen control you may give it more time.

how many times does the light blink? There is a diagnostic set-up built into these Sony TV sets.
