No sound


Sometimes it is as simple as pulling the powerplugs of the system and then powering it up again. This resets the system and may get you going again. Also make sure that the cable between the center and the bass module is well plugged in. to be sure unplug and replug on both ends. If that does not work your unit needs to go back to Bose.

Just got home from vacation and hit the on button and sony kdl52xbr9 is dead. no pix (not a flicker)or sound. Pwr/on light comes on along with sony backlight, where to start ?


Start by switching off the hard power button in back or unplugging the unit for about a minute, then replug or repower and try. This helps with a variety of power and tuner issues. Hope this helps some:)

Power comes on but no picture


I have the same problem. After power on I just get a blue screen and no sound.

I can get a piture and sound if i do the following.

Leave the TV on for a minute or two then unplug the power while still on. Plug back in and power on. I begin to get sound, repeat and then I get a picture for a few moments then blue again. Repeat and then I get constant picture with defunct colors. I then use the remote to power off and back on an color corrects. sometimes have to repeat this as well. Sometimes it takes unplugging, replugging, and powering on up to five times before i can sit down to watch tv.

Toshiba TP55G60 shuts down and red light blinks


Check the powersupply for loose solder conncetions. Especially in the protect circuit.
There is a white waffer looking IC that has been known for the pins to pop open from the
high frequency output of the power supply.
The Powersupply is on the right side and pretty easy to tell. Please use caution when
working on this set because the caps in the powersupply can hold a good charge. If you have any doubts about doing it yourself, call a professional and hopefully the pain in the pocket won't overcome the pain threshold.
Good Luck,

TV turns off by itself


Thus the line connected to a surge protector or some kind of line protector. This can be consider.

Or if this is a crt type tv. This could be a fault on high voltage section. Horizontal output transistor or flyback. But check also for loose connection/solder crack. That clicking sound may be the relay in action.

hope i give some correct input.

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.

Problem


Sometimes these things can be fixed by unplugging, waiting a few minutes and replugging the unit in. If not, could be anything since you don't say what kind of unit you have.
