Sony TV model KV27V40 blink codes?
This set will not power up. When you first plug it in the led blinks 10
times, then the relay clicks and holds for 10 seconds and then clicks again. Then the led blinks 4 times. Thereafter as long as its plugged it does a repeating sequence of 4 blinks. Trying to turn it on during this sequence interrupts it, the relay again holds for about 10 seconds then drops out and the 4 blink sequence resumes. I found cold solder joints on the hor. driver transformer and the HOT shorted. I redid all the soldering and replaced the Hot which was a 2SC5425 with a 2SD2580. The set still does the same thing. I don't have a schematic and so I was wondering if anyone knows of any further problems with these sets or perhaps from a troubleshooting point of view could point me in the right direction. Thanks very much for any assistance. Lenny Stein, Barlen Electronics |
