Hi, just wondering if anybody can help me with a fault i have on my screen, about a year ago i went to power up my tv but a white flash came on with the blue led lights flashing 4 to 5 times, then i'd get just a black screen with only sound.....after around a day of trying it came on and the problem went away for a while. Every now and again the fault would happen but with a few tries it would work as normal again........ well last week it did it but didn't come back on....i took the tv upstairs thinking it was doomed, tried it after 3 days and it worked... powered it up many times and without fail it was ok....decided to take downstairs to the living room and then on power up the same issue....
I decided to open up the back of the screen enabling me to get to the boards, when opened all the electrical components was covered in dust, i used contact cleaner and brushed them all clean, on powerup it worked, tried 3 times without fail put the back back on and back onto of the stand thinking problem solved.
When turning on back to the screen not powering up with juat a white flash then only sound....been looking online to find help although i've read stories on screen trying to power up flashing then shutting dow...ive had none with the white flash then only sound like mine.....i suspect the YSUS board is faulty and am considering buying one from e-bay for around 50 quid...but im not sure this will fix it.....can anybody help me on this issue??
