Re: Samsung 46ES6200 random dead problem
yes 5v stby is steady...ther is no 24volt line in this supply...on CNM803 in standy 12 is coming...but when load is connected 12 volt becomes 5v..., i think
there is no current in 12volt line......Leave a comment:

Re: Sony KDL-52ex700 and others 6 blink possible fix
one 100ohms resistor on pin 6 of ic2904 was open due to gate to source shorting..replaced that and ..backlight came...but 2-3 led are also damaged in my case...need to replace them.....Leave a comment:
