Hi there! Great forum this. Hopefully someone can help me out. Basically my tv's been in storage for about 6 months (and by storage I mean someone's cold garage). Finally got it out and in my new place yesterday fully expecting it not to work, plugged it in, fired it up. It started working straight away to my surprise, didn't see any problems until few seconds later the screen began to flicker, got progressively worse and erratic over a few minutes then just went black. Power cycling it seemed to get the screen to come back on but it would again immediately begin to flicker and go off but it took less and less time to do that until eventually now it turns on but the backlight doesn't come on at all.
I shone a torch through it and discovered the screen is still working, and I managed to get sound through the speakers too so, seems like it is just the backlight not working. I found this post on these forums where SuperSkippy seems to have had the same issue as me with the same tv, except his was a blown fuse. I have tested the two fuses I could find on the power/inverter board and they aren't blown.
I was about to start testing the capacitors with my multimeter but, I've never tested caps before, the multimeter does have a capacitance setting but I don't think it's ranges are sufficient. It's automatic ranging with the capacitance test and when I tested the large yellow cap as suggested in the linked thread which says on it that it's 450v and 100uF, my multimeter eventually came up with a 204.8uF reading. Am I dong something wrong (must be, unless my meter is just pants, it was only a cheap thing)?
