hi guys,
i have a samsung PS-42Q96HD that keeps clicking, heres what i have done so far,
checked the power board, caps ect all good and have already been replaced, so i did the control board test and the set powers up and displays the test patterns perfectly, from this i assumed it was the av board that was switching the set on and off,
i ordered a 2nd had board from the well known auction site, pugged it in a the set powered up and ran perfectly for hours, powered on and off a handfull of times to be sure, all was fine so i switched the set off and left it for the night,
when i tried to power it up in the morning the set was dead no signs of life at all, so i swapped out the new board with the old one and we were back to square 1 with a clicking set, during more goggling i found the info on resetting the 24c256, so i swapped the chip off the replacement board onto the clicking board, and again the set powered up and ran perfectly.
so again i did a power down and back on to check it was good and now back to the clicking!!
i have tried shorting 5&6 on the 24c256 more times than i can remember with many variations on the length and timing of the hold/release, i also removed the chip and erased it manually and set comes on for a little longer than other times then reboots and goes back to clicking,
a new blank chip i tried same happened, there is data being written to the blank chips but its never the same when i read it back, always bytes different, am annoyed at my self for not taking a dump of the eeprom before i fitted it, and i cant seem to find one on-line anywhere,
any ideas as im running out of them feels like
but i know the bloody thing works which is annoying, got another board on order should arrive late next week so i though i would ask you guys in the meantime
sorry for the huge post but i wanted to add as much info as i could
Regards
