Re: Samsung LCD Power Board turning on and off.
Hi,
First of all thanks for all your posts and team work
I am mobile phone repairer and know a bit about electronics recently my uncles samsung tv got fault . The red light on the front blink 3 or sometime six times and no display . I took the power board out clean it with rubbing alcohol dry it and it start working after few days it again stopped working . I checked few forms and every one was saying change the capacitors but there was no leak or blown caps in my power supply . So what I did re clean the power supply board with rubbing alcohol and re-solder all the ICs , transistors, FETs , inverters and all the main components . After that I turned the tv and it is working fine . I did not have to change and caps or any thing
I would suggest to every one who is having this blinking light problem and can't see any blown or faulty caps please re heat or re solder your FETs and main components may be there is cold solder or any lose connection
Thanks
