Question about Mitsubishi WS-55315 55" Rear Projection HDTV-Ready Television
Where is a good place to find replcement Diffraction and/or Fresnel lens replacements for a Misubishi TV ? Had a "DRUNK" fall into mine !!! OUCH !!!
He says he will pay for the replacemnets, but I can't find anything locally here in West. Kentucky. Mitsubishi has been NO help !. And the local yokels here are WAY out in left field with their pricing...
Any help would be Greatly Appreciated...
Thanks in Advance.
More than likely your TV has "COOLANT" (ethylene glycol) on the circuit boards. This fluid comes from the CRT's (picture tube) this fluid is used to keep the CRT's cool, such the name. This fluid from the CRT's leak when TV is on for long periods of time, the chamber expands and the seals leak.
One can remove this fluid by using "acetone" & small brush. The fluid is hard to see, use bright light, they spots can be smaller then a DIME. Also, the fluid can corrode the parts and traces on the boards. To protect the TV in future place heavy plastic or thick cardboard over affective area, make sure TV has proper air flow around TV.
If after the fluid has been removed and TV still does not work, call an Authorized Service Center to come out and repair TV after giving you an Written Estimate. The boards are not available.
Always try resetting the TV by unplugging it for one minute then plug back into A/C outlet and ALWAYS UNPLUG TV BEFORE ATTEMPTING ANY REPAIR ON THE TV.
Good Luck, big IRISH.

You should re-consider having a tech do that for you. The access is by removing the screen assmbly which are somewhat fragile. If you want to give it a try, pull the speaker grill off, it comes off just from pulling it, there should be five screws across the bottom of the screen assy, remove those, there is also an access door on the front of the set with four screws, that has to be removed to unplug the cable that goes to the screen sensors. The screen assy has to be lifted straight up an inch or two and then you can pull it forward away from the set.
As far as cleaning the mirror and lenses, you can't get to the face of the tubes so it's the top of the lenses that you clean, just use a soft lint free cloth (cloth baby diaper) and wipe the dust off the lenses, you can slightly dampen the cloth with water if necessary, same type of cloth on the mirror and you can use a glass cleaner on it just don't press too hard on the mirror.

SOURCE: HD UPGRADE MITSUBISHI WS-55315
Check your manual, I have the same set and you need a
WD 5000 HD upgrade panel, I believe.
This TV is HD upgradeable, it is NOT HD ready, like you have
been told by other responder......

IF you have the area on either side of the picture used in the 4x3 burned---it is now burnt into the phosphor of all three picture tubes this set uses.
The real problem here is most of these sets the default setting for contrast or "picture" (same thing) is 100% and this is what burns fixed images into the tubes.
Pretty stupid, but that is how they are made--the black background in later models was replaced with a light gray one to try to prevent this.
If you do not have a warranty live with it--the cost of the three tubes would be about 900 dollars plus labor to replace them and adjust the set.
It takes less than 100 hours of use with the 4x3 up to cause this kind of problem, just like putting a fixed image on any projection set with full contrast and brightness set full--the damage is permanent.
I have replaced tubes in sets like this and when you get the tube out you can see the BURN in the phosphor.
I am sorry to give you bad news but based on your description this is what you have.
If this helped you rate this solution as I do this here for free.
