Best first step is: Good visual inspection = look for hot spots
on PCB, check caps in those areas + solder any/all bad connections,esp. low voltage regulator pins.Look the whole
board over with magnifier = solder,solder,solder...T.

Green light is flasing no picture

In most instances the flashing green (or red or other colors) indicates that the TV has engaged a "protection mode" that is to keep from causing further damage in the set.

There is one thing that you might try... Unplug the TV from the wall. Leave it unplugged for about ten minutes and then plug it back in. If this restores normal function then the microprocessor that controls your TV was confused by something usually a power spike or brown out.

If the set goes back to the same mode with the flashing light there is an internal defect that can only be corrected by a qualified Technician specializing in Televisions. There is a safety factor involved here that's why it has shut itself down in the first place

Power problems problem on

I would try a power drain:  Unplug the TV's power cable so the TV is not grounded to the house.  Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens.  If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.

Sony kv35s66: No picture, just sound and red blinking

This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.

Keep us posted.

TV turns off by itself after being on for 60 seconds

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.

Toshiba 36AX60

Often the number of red flashes symbolize an error message of a specific component. Also try unplugging for an hour or two and try it again to see if problem disappears or changes.
