Question about Toshiba 51H84 51" Rear Projection HDTV-Ready Television

1 Answer

Dim screen... Purchased the TV in Fall of '05, in Fall of '06 the screen began to dim. It's still watchable most of the time, but picture is almost as if you turned down the brightness. There's no distortion. Any ideas?

Re: Dim screen...

It could be the ballast lamp, or it could be the optical engine, can you see in the rear of the TV if you can see if the ballast lamp is lit up. usually you need to unplug the ev and remove the rear cover or at least the vant over it to see if it is lit. If it is dead replacement is usually covered under warranty, within a year or so otherwise they cost around 200-300 dollars. If not, then the Optical engine is probably having problems and I would suggest replacing it if under warranty.

WD-52525 screen is jumping all around with wavy horizontal lines etc.

Good Day;

Keep talking to the factory, it is their product. Best Buy won't replace unless it is deemed not repairable and/or terms of the contract. You purchased the extra warranty because you most have felt that the TV might break down. Well, it did, now use the contract to repair your TV.

Good Luck, big IRISH.

Picture problem

I have an older Mitsibutishi 52" HD 1080. I recently upgraded my cable box to DirecTV HDTV. When I change to format to view in 1080 the TV goes from full screen to what seems to be wide screen with a black bar on the top and bottom. If I change the format to 480p I get a full screen; but the picture has a "redish tint" over it as if looking through sunglasses...I tried everything in my TV manual even call the cable company. Any suggestions?

Mits 46805 - Replaced IC's now picture is dim!

Good Day, Nickb2b;

The IC's you installed will not cause a dark/dim picture......but I would like you to check two things:

1. Make sure you put all cables that you may have unplugged into their proper positions, the cables are marked with numbers, ensure all cables are properly seated,

2. Look for fluid on the PCB's.

Good Luck, big IRISH.

How can I clean the mirrors on this tv?

to clean the mirrors you must remove the screen first there are several screws in the back to remove the screen. then there is a mirror shaped like a polligon clean this with a dry cloth do not use a paper towel. soft colth must be used on any optical surface. then clean the optical engine lens in the same manner. them the large mirror in the back. remeber if you leave a defect on any of these surfaces it will be amplified by the screen. this system relies on a lamp to provide bright picture so replace that as well. this should be a part of your anual cleaning agreement of the after market warranty you purchased assuming you bought one. dim picture = lamp, fuzzy, dim, dull picture = dust

My LT37HVS was purchased in 2006 and the LCD light engine "blew" with a loud noise and only displays super dim picture-in-picture component feeds.
