SOURCE: red light on power button flashes, but no picture....blank screen

I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.

SOURCE: no power

Dell has a recall on this item (at least for no power). I purchased mine in 2006 and there is apparently a 3 year window where you will get a new one replaced for free. Just call tech support give them your service tag, and ask to have it replaced under the recall.

SOURCE: when I push the power button, the blue light comes on but tv doesn't

It is the capacitor. It is really easy to fix, and it will cost you about $4. The capacitor is on the power board and it looks like a small battery. The bad capacitor will have a small bulge on the top, the good ones will be flat on top. You can buy them at Radio Shack. Just look on the side of the capacitor to see which one you will need. If you need any further info I would by glad to help. I have a 40in polaroid that this happened to and it works like a dream now.

My coby-514 dvd won't open up when the open/close

disc is stuck, remove cover screws and carefully remove the disc, do not force the unit, once the disc is out use the remote to close the unit, then use remote to open and use a different disc press play and hopefully it will work, try to avoid not using the remote for all functions,including open-close. do not push tray in manually.
