TV just turned off while watching it - red power light flashing now and burning smell

The flashing red light means there is a problem that cannot be fixed on it's own. there is a good chance it is shot. You may have to take it in but most likeley it will cost close what replacing it would cost.

My tv will start to power on and then will shut off again. It takes up to five times to get it to stay on. What is broken?

Hi, Ashley. I hope I can help you out today.

What it sounds like is happening, is that one or more of your capacitors has failed, so the remaining ones are trying to compensate and still function properly, thats why it is slow to start up.
Capacitors are like little booster batteries that get the tv a kick start to get it going.
Well, unfortunately they burn out sometimes, and when they do, they cause this exact kind of sluggish response to powering on the tv. It takes that many tries because your not getting a full boost all at once. The capacitors look like little cans, or batteries almost, standing up and down.
The damaged ones will either look like a leaky battery, or be split down the side, or have the top bulged up, or some even pop like a little balloon. They will leave a wet residue on the circuit board as well.
Although they "can" be fixed as a do-it-yourself project, I would suggest that you take it to your local Fry's or BestBuy. They both have specially trained techs for this specific repair.
Also, know that depending on how many capacitors are shot, and how much labor will be involved in the repairs, it may cost as much for a new tv as it is to fix the old one.

Green fuzz on screen

If the green fuzz is only seen sometimes, it may be a cable issue. Check your cables to see they are tight and perhaps even replace them if the issue persists. If this doesn't solve your problem, the TV may have technical problems beyond your ability to fix - sounds like power issues.

Vertical red line on 55 hitachi plazma

The vertical line, in my case, was due to a bad contact on the flexible printed circuit. I fixed the problem by using a piece of a rubber eraser to apply downward pressure on the flexible circuit as shown in the picture. To locate the faulty section lightly push on the flexible circuit from lef to right untill the line dissapears.
