Question about Toshiba 50HM67 50" HDTV
Dark smudge (see real good when its light on TVshow) has appeared. It just suddenly appeared. Is the inside of the screen need cleaning? or is it somethin else. Also started pixelating some, I think that is tv provider problem.

It's either signal board or light engine and unless you're really pretty good at electronics neither one is something you should tackle. I do have the service manual for this unit and I would be glad to send it.. Just drop me an email firstname.lastname@example.org and make sure you include the model number as well as what it is you need.. I get almost 650 emails a day so it's really hard to remember who's email goes with what problem. :) Good Luck Bill

Yes I Had The Same problem , if your handy with fixing things this will
Step 1- unplug the TV from wall socket
Step 2- disconnect all devices like VCR's DVD Players from the TV
Step 3- remove the speaker covers from the TV
Step 4 - There are 14 screws on front cover, remove these with a
Philips driver, set cover aside
clean with soft brush and wash with water
Step 5- Gently raise the cover straight up to release it from its supports
Once cleared from supports , remove the cover.
Tips- Make sure you don't scratch any of the screens or CRTs
You can clean the mirror with any glass cleaner, make sure to wipe it
clean , water and vinegar does a good job to eliminate streaks.
Use a soft duster to clean the dust from the circut boards
Tip - Remember take it easy when cleaning
When your finished cleaning, just reverse the steps

Testimonial: "It came in very handy!!! Thank's for taking the time to write me the tips. Even if I got the answer to my problem 5 months later.Thank's again Lanzer"
SOURCE: I recently replaced the lamp
This is problem of DMD chip that generates picture/ image in this tv and DMD chip is not available separately so complete light engine will be replaced to fix this issue. It is bit costly fix.
Click Discount-Merchant link to view light engine images and they offer required light engine for $330 and local tv repairman will help you to replace it because it needs expertise and skills.
Hope these info will help you.
