Hello there, my TV has recently started acting up but it doesn't seem to be dead.
Basically it runs for about 30 or 40 minutes after being turned on, but then shuts off with the 7 blinking lights code.
I tested the SD and SU boards with a multi meter and could not detect any shorts on any of the pins.
I was considering getting a new TV but I actually don't want to let this baby go, I still honestly love the picture on it. If it didn't turn on at all, I would consider it more "dead" but the fact that it will continue to turn on (even now) and then turns off after a certain amount of time, really convinces me that it is fixable.
I am thinking maybe its something to do with power ? once a component reaches a certain temperature it shuts down maybe ?
I am pretty smart with electronics, but very in-experienced when it comes to circuit boards, voltages, capaciters etc etc.
Would love any help or advice on the next best course of action in fixing this TV. Anyone have any ideas? Or seen similar behaviour before and have an idea what could be wrong ? Something else on the TV I should be testing with the multi meter ? I don't want to switch out any boards until I know what board is causing problems.
Any help is appreciated, I feel determined to get this TV back up and running.
Thanks !
