Hi I have a LCD tv that works sometimes and doesn't other times. I have attached some pics. When I power the tv up the red stand by light comes on, when I switch the tv on the light flashes 3 times and then the blue on light comes on. Sometimes the screen lights up but more often it just stays off. I have checked for standby 5V and have it at the connector that goes to the large board from the PS at all times even when the tv does not start. No 24V or 12V to be found. When the set did actually power up I checked for all the voltages and all was as it should be. I suspect a bad joint some where and have already done a bit of re soldering on all boards to no effect. Does anyone have any ideas what could be the problem or where I could start looking? Could dodgy caps be the problem? Do they cause intermittent problems like this? I appreciate any help you may be able to give me. Hopefully the pics will be of some use.
Thanks
