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 premtech@willapabay.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

SOURCE: Good morning, I need to clean inside of my Toshiba

Yes I Had The Same problem , if your handy with fixing things this will
work.
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

It Worked for Me

SOURCE: I recently replaced the lamp

Hi,
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.
Thanks.

Seems to be missing on one cyl.


Find a real dark spot, on a real dark nite. Raise the hood and check the plug wires for any spark jumping.
Also check all the vacuum hoses, fittings, pcv valve.

Spots all over screen


We will presume you have a DLP set that uses a lamp of some sort(no brand or model indicated here).

spots or dead pixels are usually a damaged optical light engine--there are ones where more and more appear.

A faint possible reason is dust is inside the optical light engine--seen it a few times but the spots are usually golf ball in size----high pressure air applied to the vents in the engine with set on in a dark room usually clears that up.

How do i replace the mirror on a 50hm67


Two issues here: one is if mirror broke and fell forward into screen the marks are permanent.

Changing the mirror involves getting entire front of set apart and off--a lot of screws from rear and inside the set---to see what is involved you might want to TRY to search for the service manual for this set---I have done this before and it takes time and care---mirror will be over 100 plus shipping---might want to GOOGLE the model with "mirror"

Dark smudges/spots on my HDTV screen


The model indicated here Sony Grand WEGA KDF-50WE655 is a LCD rear projection and rarely if ever requires cleaning.

If black spots or such are gradually appearing the issue on this model is the optical light engine.

Set uses a LCD engine which the lamp shines directly into and heat from that very hot lamp can damage sensitive baffles inside the engine.

I would suggest also you contact Sony as they have on several models extended the warranty for this kind of issue---Engine is very expensive part and several of these Sony sets were involved in a class action lawsuit--hence they are dealing with them.

Do not take no for an answer if you want them to help you---the hinge that is sqeeks gets oiled...........

I have toshiba 50hm67 replaced lamp...tv worked, then quit working again, and giving blinking yellow lamp error light when turn on...after a few moments tv tries to turn off and back on


OK. I have this same issue. I replaced my bulb a month or so ago. TV worked fine. Then one morning I turned it on and it was on for a good while, till it went to a black screen w/ sound only. Lights were going through the reboot process as designed for 8 attempts before it went to the solid red light. From the red light, if I unplug and plug back in, the tv will come on for a given amount of time, which varies, and then cut to the black screen. A repairman told me that it sounds like the digital board is bad. He wanted $150 for the board and $100 labor. I cannot find anywhere where the board would be located or where I can purchase a replacement.

Recently replaced blown lamp for 50HM67 50 inch tv. Now have picture but clarity is off. Picture / screen words are very blurry. Toshiba referred a local repair company who mentioned that the problem...


If the picture was good before the lamp blew, there might be dust/splatter on the window in front of the lamp. Pull out the lamp assembly and look at the small square glass window that the light shines into. It should be clear and clean. If it is not, clean it gently with isoprophonol alcohol or screen cleaner.
By the way, there is no such thing as convergence adjustment on DLP TVs.

Have two dark smudges on screen


Dear Chaplink,

You said "two dark smudges on monitor screen".

Asumming that these smudges are digital and not just something tata you can remove with cleaner, If your moniter is back-projecting then the issue is probably that the projector has been damaged.

If your monitor is a flat-screen then the gels inside of it are misplaced from somone touching and damaging your screen.

So basically, the only practical thing you can do is buy a new monitor.

Smudge on pictures


Yes, if you have used different lenses and a smudge still appears (in the same place) there may be something on your sensor. Have you cleaned or touched the sensor in the past? Typically sensors only get dust (shows up as small fuzzy dark spots) on the sensor, not smudges.
