    I have several blue spots on my screen and the longer I watch TV the bigger they get

    Blue spots appearing along bottom of screen and seem to be "blue tinting" the picture above the spots.. sounds like the same problem with a light engine others are having. Second time this would have been replaced for the set.. any opinions or advice?

    About 6 months ago we started to notice a blue spot on the lower right corner of the screen. Then last night the lamp went out so we replaced it. Since putting in the new lamp the blue spot has taken over the entire screen. Please help me fix this problem. This TV is not even 3 years old and so far I am not impressed.

You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).

Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck

Today my haier Plasma TV (42HP25BAT) did a terrible click sound and post which the screen of TV went purple with out blue color and less brightness than normal. When there is no signal to TV , it...


Purple? Would that be magenta? That's what you get when you lose the green color. Lower brightness may be due a shift in one of the power supply voltages. I'm not familiar with the layout of this model, but the first thing I'd do is inspect the power supply to see if something exploded - possibly an electrolytic capacitor.

Another possibility is a high-voltage component on the plasma driver board. Check anything mounted on a heat sink (metal plate or slab with fins).

Are the black spots just in one corner of the display? Do they show up the same no matter what the program material is? If so, I'd be concerned that you had an arc inside the display itself and it is damaged. The arc could have taken out the green drive. It is possible that it's a problem in the video circuit, but usually that would show up as a bad row or column. (If it is indeed a fault due to arcing in the display, you may able to see a difference between the bad areas and the rest of the screen with a magnifying glass and bright light when the set is turned off.)

I've noticed a dark patch in the lower right corner of the screen. Is this a bad panel or backlight? It's mostly visible in scenes containing blues.


Sounds like a backlight is out probably due to a bad inverter board. If you can see the spot when the tv is off its probably a bad lcd panel.

BLUE IMAGE ON FLAT SCREEN


As I'm sure you will notice that you rub your finger accross the lcd panel when it is on and you will see a blue trail as you cross the screen. I would simply try to wipe the spot with a soft dry cloth while the unit is on and see if that corrects the problem. If not I'm sorry to say that the lcd panel has been damaged.
