I have sony 29'' crt tv . model no KV-DZM61 .when the tv statrs on it shows green led,and after few second the led glows red and it blinked for 2 times .then the tv goes in stand by mode


2 blinks means - over current protection (OCP) , unit goes to the standby
mode then displays the 2 blink fault. Could be a short in the power supply of
any of the circuits.

My sony trinitron xbr tv turns on stays on a few seconds then powers off by its self and it gives 5 red blinks from stand-by


This is according to the sony service manual

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.

Sounds like a failure in the C Board or AKB Circuit.

Best to take it in to a service center.

I have a sony 29'' crt tv . model no kv 29xr m80.when the tv statrs on it shows green led,and after few second the led glows red and it blinked for 8 times .then the tv goes in stand by mode .which section...


Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

Standby mode intermittently.


Hello, FixYa

I have normal tv model CNT 2588 code 981, remote control was out of order and I tried to buy a new one from many places in UAE, Suadi Arabia & Egypt but I failed due to it is old model and no spare parts. So I use the tv function through Satel Decoder and use tv main power button for swithing on and off. It seems that caused a problem and tv now could not get power to switch on. Would you e-mail me with the repair manual including the Elect.Circuit to try to repair the problem. Also if you can arrange to send me a new remote control model CNT 2588 code 980. Since the TV Picture and sound are still in an excellant condition, please e-mail me you kind response with the cost if any to send you my Address and money.

Thanks in advanced.

GE 31GT740 clicks off and on


Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply
Reverts to standby from switch on via TV or Video
No 5v rail because FET MTP3055 o/c. (BUZ71 will do nicely)
Goes straight to standby, after a quick burst of power
Replaced R952 (39K), had gone slightly high
