TV has been working fine, but now seems stuck in some kind of "sleep" mode. When turned on, the power indicator flashes on and off continually, but no picture or audio - just black screen. By toggling the ANT button on the set or the TV/Video button on the remote, I can hear that the set is switching input signals, but still no picture or audio. I've tried switching the set on and off, reconnecting everything, even leaving it on for hours in this current state, but no change. Any help would be appreciated. Thanks.

Re: Flashing power indicator
Generally a blinking light such as you described indicates a "shut-down" condition which usually means something has shorted.
AS our guest said it would take a tech and some trouble shooting to find your problem.
Sounds like a power supply problem unless there is a short in the deflection circuits causing the power light to flash. I'm afraid it'll take a technican to figure out what is wrong. If it's more than 7 years old, you might consider replacing it.

3-blinks by the SONY TV error code indicates that there is an audio circuit problem, ether is a shorted audio amp IC on the main board, or the power supply that supply the power to the audio amp section is defective.
Flashing power light indicates that there's a problem with the RAM. You're referring to a Standy by mode when you turned on the computer. If you have a spare ram you can try to use 1 to check if the RAM that you're using is faulty. Mobo is fine dont need to worry about that. No need to remove the CMOS battery. If you know someone who has the same ram or another computer you can try that. Usually it happens to Desktop Computers that monitor was on standby mode when they have a bad ram.
Yes, you have power supply issue. the power on circuit is malfunctioning and the flashes is the indication that the voltage levels for the power on regulation is not correct therefore shut down to protect the circuit from further damage. You TV unit needs servicing by an plasma TV specialist. Also check to see if you do not have the TV in sleep or hibernation mode.
The flashing will come on if the chair is in neutral or if the charger is still plugged in when you turn it on. Place the chair in neutral (freewheel) by shifting the levers out, then place firmly back into drive.
Unplug from the charger and it should fire up. Sometimes, the chair will also go into "sleep mode".
Check your owners manual for this. Note, some have sleep mode potential but it's not in the manual, and if someone inadvertantly hits the right series of motions with the joystick, you can inadvertantly put it to sleep. Try turning the chair off, wait three seconds and power back up, then immediately press the "horn" button. This wakes up most of them. Others you need to power off, turn back on and then move the joystick forward, backward then forward again.
If possible, try a friends monitor first. If it works, you can then change the sleep mode setting so that it won't come on again. If the other monitor does not work, the video card is probably defective.
