Question about Sharp Aquos LC-32D40U Television
Set powers-on normally, but a few seconds later the screen goes black. After losing the picture, the sound continues, channel can be changed, etc. Regardles of the time interval between powering down and powering up this cycle is repeated. NOTE: Model # on the back of the TV is LC-40D32U. Techial service @ Sharp told me it th same as LC-32D40U; however, the hook-ups are vertical on my set and horizontal on the LC-32D40U.
I believe he is right about those models being basically the same. They often make small changes like the layout of connectors so that they can have different models to sell to each store. It defeats the "price matching" ads some stores use. It sounds like one of two issues. Either a bad capacitor (a very common problem on this model, apparently) or a heat issue. Since it seems to happen every time, even if the machine has been offline for a while, and it takes so little time to do, I'm inclined to throw out the heat issue. Open up the back and see if you see any capacitors leaking, or crooked. I can't find images for capacitors in your machine, but I did find a site about bad capacitors on PC system boards - the capacitors are basically the same thing, so it might help you identify that. http://www.badcaps.net/pages.php?vid=5 If you do see bad capacitors, either solder on new ones, or just replace the entire board. It should be simple to replace. I can't find parts for this online, but you should be able to get them either from Sharp or from a local repair shop.
