Re: LCD TV SHARP LC-32SH340E can't start
I never tested Optocoupler before. How can I do it? There is LED at pin 1 and 2, I tested it with digital multimeter in diode test mode and diode is OK. But what next...

Sorry for bad quality, not easy in night
I found brown place right under IC803 (MDS5852), it's on photo, looks like it was overheated....

I can't find any schema of this PSU. Do you have any? It's 17PW82-2 v.1 090511.
Some people told me that i should check CCFL backlight by entering service mode, where should be record of errors. But I can't enter it. Tv does not response.Last edited by andrasin; 02-09-2014, 02:08 PM.

LCD TV SHARP LC-32SH340E can't start
Hi, I have LCD TV SHARP LC-32SH340E. There is 17MB60-4 mainboard. The problem is that if TV is on stand-by, front LED flashes. When I try to turn it on, LED starts to flash little bit faster, takes 5 seconds and than it falls back into standby mode and LED flashes slower again. Display never doesn't lights up. Do you have any ideas what can be wrong and what should i try to do?
