Question about Mitsubishi WS-55513 55" Rear Projection HDTV

Open Question

I have a 55511 Big Screen and need replacement parts?

Where can i find a circuit board and a lens for the projection of the tv, and how much would that cost, also replacement lamps..? i feel confident i can fix this tv if i can get these parts, possibly the fuses have all been burned out because some liquid from the lens came out onto the circuit board.

Thank you
Roy Gonzales

SOURCE: 1998 mitsubishi big screen model VS-50603

this model is famous for fluid leaks. each projector tube has a reservoir on the front of it with a fluid in it. this keeps the face of the tube cool.
this depends on how bad the damage is in the tv. in most cases we can reseal the tube and clean up the fluid 400-600.
Once you
take the tube out you will see where it leaked. The problem is that the
frame on the CRT that the heavy screws with springs are mounted on (that
hold the lens coupled to the CRT) is weak and they can bend. We have seen
several that have leaked after the customer moved the set. You can only
tighten them down so much because the frame bends. It is just stamped metal
and not welded at the corners to support the bend.

We remove the CRT, clean it all up, add a very small amount of RTV sealer to
the gasket, reassemble, let the RTV cure thoroughly and refill with coolant.
The extra sealer should prevent future leaks. Haven't had a recall yet.
Mits says replace the CRT...too costly.

You msut check the yokes carefully as well. If any coolant gets into them
you can end up with shorts there and a mess.

Clean the boards carefully and repair any corrosion damage. The coolant is
ethylene glycol and glycerine which is water soluable.

Listen: you need to wait for the set to first shut off! then push on the TV(not the remote) Input and Menu both at the same time for 5 seconds and then release---the power light will then blink---this model has this feature--

You can probably purchase a smilar set on Craig's list for $300.00, at least that's what they go for in the Austin Texas area.
A new tube may be too expensive and difficult to replace.

SOURCE: I have a mitsubishi ws

Age of unit: About 7 years.
Rear Projection HD set, Mitsubishi WS-55511
Nature of problem: Blinking green light of death. Upon plugging the set back in after vacation, the green LED on the front of the set would blink continuously and the set would not turn on. I ordered the blinking green light kit from tvrepairkits.com after seeing this link on a tech forum, suggesting the capacitors were bad on the DM board inside the DM module. The kit arrived within days of ordering. The online instuctions were very detailed and could be followed even by a layman such as myself. Very detailed with lots of photos. My DM module was simpler to remove than the instructions indicated. It simply slid out after about five cables were disconnected from other boards. The module itself is the silver box all the way to the left when looking into the rear of the TV (from the rear of course). There is a plastic guard that surround all the input connections (coaxial connections, home theater control inputs, etc). This is removed with 3 screws. After all the cables to this module are unplugged from other circuit boards, the module will slide out towards you. Then you take the cover off (including the clamp where all the cables are routed into the module) and you can see the DM board (it is labled as such and has 7 capacitors. None of the capacitors were bulged or otherwise defective looking as other posters have reported. Changed them all anyway. Buckled everything up and plugged the set back in. The blinking light started as it always had. It should normally go out in about a minute after plugging in to wall. I really didn't hold out a lot of hope that it would go out....and then....it went out! I pushed the power button and she fired right up! What a thrill! Including shipping, it cost me $45.90 to fix a set I paid about 3000 bucks for 7 years ago and was loathe to just throw away. I certainly wasn't going to pay nearly a thousand bucks to fix this set. It may be a little bulky, but the picture is beautiful as well as the sound system. You guys are great. A very reasonably priced gamble that worked. Watching a movie in HD while I type this, good to have my TV back after almost two weeks without it. I actually can't believe I did it!

Liquid coolant in big screen tv, what is it?


It is a very toxic material called Glycol==if touched it gets absorbed into your body by contact--there to keep the picture tubes cool.

Lens should never be taken apart---if it got on the circuit boards it will short things out and start dissolving leads and the actual board as well.

This means your tv needs to be serviced,more than likely the lamp is dead.These are pricey but easy to replace.Most lamps only have a life of 5,000 hours.

On my WS-55511 TV, after a power interruption, will not power up. All i get is a continuos blinking green light.I tried unpluging the tv several times, no luck.


Good Day,

LED does not stop blinking after plug in. Check for 12 volts at connect or PF pin 10 and 28 volts at connector PF pin 11, (on the board on the right hand side, but on the left side of board towards the back of TV). If the supplies are correct suspect a problem in the DM Assembly (part # 955C230002). Part is not available for replacement.

Check C9B01, C9B02, C9B03, C9B13, C9B14, C9B17 and C9B18 (1000 UFD, 16V, 105C) on the DM Power PCB located within the DM Assembly. If they are bad or not, replace them all with part # 181P734030 (680 UFD, 16V, 105C).


The DM (Digital Module) Assembly is located on the extreme left of the chassis from the back. It is standing in a vertical position. Remove cover and you see the Cap’s in one corner of the inside PCB.

Good Luck, Big IRISH.

Mitsubishi HDTV 1080, model WS-55511. Color convergence is off but only on the outsides of the screen; in the center it is fine. Can this be fixed or do I need to replace the television?


Yes, it can be repaired, replace convergence out chips (two ICs) on main board.
If you are not comfortable with TV repair or have no experience, call local tech to fix it. Cost of repair would be $180 or so.

Hi,
Post shows its Mitsubishi WS-55511 TV, if that's correct then check convergence section for dry solder joints and resold these joints. Specially check convergence out ICs pins.
Below is an exploded image of main board of TV and convergence area is marked to have an idea...
Let me know if problem remains to check further options.
Thanks.

Good Day;

Sounds like you have bad Convergence Output IC > 267P155010 > STK393-110, replace and it will correct the problem TV uses only ONE, make sure all resistors look good in the circuit around IC.
Good Luck, big IRISH.
