In standby mode (red led on/after the led stops from blinking), press "Display", "5", Volume (-)", "Power on" on the remote control in sequence, self diagnostic screen will be display, let me know the what is on the screen to diagnose where the fault came from.

Hi,
If you see standby red light blinking on Tv front with 3 seconds interval then count its blinks from pause to pause and let me know, its an error code.
And if TV does not even show standby light then check fuse in power supply that would be blew off for some reason, replace it.
Still problem? let me know with exact model number of your Sony TV.
Thanks.

Those 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.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My Sony XBR800 won't start and the standby light blinks 7 times with a 3 sec. interval before blinking again.

Sounds like the power supply needs replacing.

TV repair is best done by a pro unless one has significant experience with it.

This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.

Please count light flashing again. Light flash time is "0.3 Sec" and there would be pause (light Off time) for "3 Sec". Start counting after pause to next pause.

it is an error code of the sony maybe there is a problem in it.

tv turned off black screen and red light flashes 6 times over and over again
