SOURCE: sharp aquos red flashing light tv won't get picture

if the tv is still under the manufactuer warranty i would definitly give them a call. If it is a Sharp tv I would call the 1-87-BESHARP. I would also try unplugging the tv for at least 2-3 minutes and seeing if the tv will reset itself. Usually what happens with these tv's when the light blinks it locks the tv as a security issue. If the unplug does not help it will more than likely need service to get this fixed for you. The call line hours are M-F 7am-7pm S-S 9-5 and they will be glad to help you from there.

SOURCE: flashing red light

Your power supply is faulty I'm afraid. Unless you have soldering skills, I am afraid you will need to contact a professional TV repair person. If you feel confident to try the repair, contact me with the model number, and I will let you know what components you need to change

SOURCE: After a momentary power outage Panasonic LCD TV has a flashing red light and will not turn on.

Try using a different outlet, the outlet or the tv may have been damaged in the surge. In the case of the tv contact the manufacturer and see if it's still under warranty. There may also be a way to 'reset' the tv by holding the power button down, try looking in the manual or calling customer support. In the future use a surge protector, many of today's electronics are still sensitive to power surges, older tv's were more resilliant than today's in this regard.

Turn tv on. green light solid display, no picture or sound


The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

I have sony kv-32s25 powers on but no picture i do have sound and the stand by light is flashing and idea's


The key here is the standby light flashing. It should be flashing in a repeated count of flashes with a pause inbetween. Count the blinks and report that number here. This is a diagnostic code indicating the circuit that is having a problem. Armed with that info, we should be able to give you an idea of the problem and its solution.

Thanks,

Red light flashing...no picture. TV not turning


Probably a failed main power supply. There are at least two supplies; one that keeps the remote function alive continuously and the second that is turned on when the set is ordered to operate. The smaller supply is a low voltage circuit and that is providing your error indication.

Flashing green light


Did you try this yet

SYSTEM RESET
If the TV will not respond to either the remote control
or the front panel controls and/or will not power Off,
press the SYSTEM RESET button with a pointed item
like the end point of a paperclip. The TV will turn Off
and the TIMER light will flash quickly for about one
minute. When the TIMER light stops flashing, you may
turn on the TV again. Changes you made the last time
the TV was On before you used the SYSTEM RESET
button may be lost, however, the changes you made
previously are not lost.
POWER/TIMER Indicator
The green light is a multi-function indicator. This light
will flash rapidly for about one minute each time the TV
is plugged into the wall electrical outlet, when power
is restored after a power failure, or using the SYSTEM
RESET button. Do not attempt to turn on the TV again
during this period. Wait for the flashing to stop and
the light to turn off, before attempting to turn the TV
on. While the TV is powered on, the light illuminates
steadily. If the TV has been programmed to turn on
automatically using the Timer feature,

Could be a weak Picture tube . You can try turning up the screen control but don't turn it up too much you'll get retrace lines in the picture . Turn it alittle at time until picture comes on then turn it down until the retrace lines go away . Then try turning the tv on and off to make sure it comes back on. Be careful you can get shocked if you do this while it is on and you touch one of the circuits . The control is on the flyback or the module thats on the picture tube it will say screen by it . If this does not work you could have vidoe problems or just the picture is no good . Good luck
