I have the same problem. When using the remote, it makes the clicking sounds like it turns on, then immediately makes the clicking sound of turning off. The LED blinks repeatedly 6 times over and over.
I *did* get it to come back on by holding the power button down for about 5 seconds. Now I'm afraid to turn it off again! :(

Sony wega trinitron will not stay on


Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

40'' Sony Bravia goes into standby with the light blinking 9 times


I finally managed to solve this problem by unplugging everything - scarts - HDD cables - power etc and left it for an hour. When I turned it back on again the problem had sorted itself out.

I pressed the sleep button by accident and the pic and sound went off and the stand by/timer red light started blinking. what does it mean?


Depends on how many times it blinks,just count the blinks Example: if it blink 2 times then pauses and blink 5 times then the code would be 25 and so on

Once you have this code,please post it.

Standby light keeps blinking. tv wont turn on


If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
