Dim picture from one broken lamp??

I recently transported a toshiba 65h84 65 inch projection in the back of a truck. i had the tv wrapped in 2 tarps coushioned by several blankets, coverd with a weather proof sleeping bad, and wrapped several times over in shrink wrap.... upon transporting it, it started to rain. well we arrived at our destinaton and unwrapped the tv. we noticed a little water around the base but not much, however once inside, the screen had signs of water trapped in between the main glare cover, the thin 2nd screen and the 3 screen that look like a big circular lens. but just a few inches tall all the way across, we took all 3 screen off and dried them individualy. we noticed that the inside by the projection lamps was dry and didnt give it a second thought. when we finally powered it up, the screen was barely illuminating and it was ovbiously blue, which later we noticed the red bulb was not working, my queston, would the red bulb provide that much more light to the screen, blue and green work but u can hardly see the menu window come on let alone the picture. Or could we have put the multilayer screen on wrong or damaged it?? hopefully that provides some info enough to go on// thank you for any help...c

The red CRT is most likely not the culprit. If water got on to any of the boards such as the red CRT driver board it could damage it wich also at the same time can load down voltages (200 volts etc) that can have a global affect on the other CRT's. Changing any on the CRT's by the average consumer is NOT recommended because you are dealing with a device that requires 30 KV (thats thirty thousand) volts to make it light up. Take these as warnings and consult with a technician.

Re: dim picture from one broken lamp??

The red is a big part of the picture quality and brightness of the tv. However if one is damaged I definately would try changing the bulb and then calibrate the tv with a calibration dvd. Hopefully this helps.

How do I fix My 50 inch Hitachi Ultravision TV?

Likely the lamp in the set has failed here which does make sense if the picture was dim before---a lot of lamps just before failing all the way dim down.

Green light stays on red light blinks set won,t go on but bulb does not look blown also fan does not run after tv is shut off like it use to before and tv shuts itself off after a while when it does work...

With a dim picture even if lamp looks ok I would make it suspect number one---going to have to decide if you want to buy a new lamp to find out--average life is 1-2 thousand hours.

My sony 50 inch lcd projection tv from 2003 has a very dim picture. We replaced the bulb and there is no difference. Any suggestions?

It could be that your lamp is misaligned - if it is not shining directly, the picture may still display perfectly well, just dim.
It is also possible that the power going to the lamp is decreased.
If replacing the lamp did not solve the issue, it's likely a power problem, and that will likely require assistance from someone trained in the filed.

These Toshiba DLP's were lemons.
There was a class action lawsuit in the US and Toshiba were forced to issue a recall on the lamps. Toshiba replaced the first lamp for free but when the lamps are burning out every 6 months at a replacement cost of $200 these tv's are expensive to run.
Sounds to me like the light engine has failed. This will probably be a $800-$1000 repair.
Scrap it and take the hit.

Toshiba 55 inch hdtv lamp

this is a crt type tv- no lamps just crt's if it was moved recently then a seal could have been damaged on the crt cuasing coolant to leak down the neck getting into the socket. this will cause trouble for sure also could have a crack in the crt. look for a sticky liquid in the bottom of the unit.
sometime the crt's can ark and rip out a video output chip on the crt socket check it out.
not common but not unheard of.cheers

Toshiba 52HMX95 DLP has weird gray think line

DLP TVs work projecting light throught a tube covered with mirrors, called the light tunnel.

The gray shadow it is something in the middle of the light tunnel, probably a mirror that has gone out of place when you moved the TV.

Picture seems to be alot darker than before. toshiba 62hm95

I just replaced a lamp in a Sony LCD projection that was just over a year old and it was bad. It was a VERY dim picture. You have a DLP but, in either case a dim or dark picture is almost always caused by the lamp.
