Not any more since live far from there for now---call around--Poway TV does have a guy who ought to do it in the home----Alex---watch out for craigslist as a few scammers are there.

If this set uses two chips (common) make sure whoever fixes it changes both.

SOURCE: WS-55511 Mitsubishi projection TV is stuck on INPUT 4.

This model was first made in 2002 and is a V21 Mitsubishi chassis.

I presume the front input or device button does not do anything.

This (if it is a WS-55511) has an option code that can be accessed. It will reset everything back to the condition the set was in when it was new in the box; once executed you will have to put it in the cable band and autoprogram it----email me if you need instructions for this and I will give them to you.

If this was helpful I would appreciate a vote from you.

SOURCE: Mitsubishi WS-65809 - works, but screen won't power on.

yes that is correct 12 is normal...make sure all connectors are plugged in and in the correct places . conectors should be marked with letters that match the marking on the circuit board. Then look for heaters , in the glass bottom of the picture tubes(CRTs) there should be a little orange glow visable though the neck of the CRTs just above where the crt boards plugg onto the bottom. if the heaters are not glowing then check your wires to the crt boards again , you probly tugged one of them too hard during disassembly also check for cracked solder in the heater circuit......Oh yeah, you didn't mention -Does the TV get high voltage ??? thats important to having a picture......If you see the heaters glowing when the tv is on then look down into the lenses of the crts . If you see a brite color horizontal line closer to one side in each of them then you know most of the tv is working. If that line is curved then the tv probly detects that the convergence circuit is not working and it is blanking video.
OR -----
the error is 21 (see what number it ends the sequence with..) . Error 21 is X_Ray protect and you probly plugged one of the connectors into the diagnosic connector(near the high voltage transformer- normally nothing goes there) . If that is the case then somthing in the H.V. circuit could have been permanently damaged and now the tv has a new problem and wont work even if you put that connector in the right place.

SOURCE: how to reset convergence? on mitsubishi ws 55511,

There is an option in the user menu on the tv. Using either the remote or control panel on the front of the tv, press MENU then select SETUP. After you choose SETUP go to the 3rd column with the 3 icons. Here you can adjust the red or blue color or reset the convergence back to factory default.

After a few years the set will begin to show increasing problems with the convergence settings. When you can no longer adjust either red or blue horizontally or vertically an IC replacement will be needed. Your set uses (1) SANYO stk393-110 and you want to make sure it's SANYO and not a knock off brand as those usually fail prematurely.

Ws-55511 green light changed caps. where is pico fuse located ?

There are at least two pico fuses in the DM unit along with the caps; DM is large metal box on left as you look from behind.

Blinking green light that does not stop means problem is in DM unit that is not booting up.

If you have questions let me know.

What does code 2.2 mean. that's what i get on my ws-55313 ty.

It means short protection.

98% chance one of the two pico fuses that protect the convergence circuit is blown.

Repair entails replacing the two STK-394-250 CHIPS AND THE BLOWN FUSE.

This may or may not be a do it yourself repair.

Let me know if you have questions, total parts cost would be about 35 dollars.

Attn sd tech i have a code 2 2 how do i repair?

It means one of the two pico fuses for CONVERGENCE is blown.

I will attach photo of the fuses; they and the two convergence chips this set uses are on the middle circuit board--also a photo of a typical IC.

Parts cost on EBAY will be under 20 dollars.

Instructions tell you everything you will need and exactly how to do the repair.

Give me a email and I will send them free.

If this was helpful rate this solution as very helpful as I do this here for free.

We have a WS 65511 with an error code 2,2. What does it mean and how can we fix it?

I am a expert on these sets and have fixed hundreds of them.

2,2 is short protection and 97% chance one or both of the pico fuses that protect the convergence circuit are blown (bad).

Model indicated uses a single STK-393-110 convergence IC. The fuses and chip are on the middle circuit board which needs to be removed to repair the set. Total parts cost will be under 25 dollars---I use a seller on EBAY who has the chip and the fuses.

I have start to finish step by step instructions for this repair in this model as I have done it hundreds of times.

Soldering and some skill are involved in getting the board out and replacing the parts.

let me know if I can assist you or if you have questions let me know here.

If you decide to repost this question mark it "attention SD TECH"

Mitsubishi ws-65907 tv will not power on

one of the two pico fuses that protect the convergence chips this model uses is gone--see attached photo--

NEVER change just the fuses---if one of the two fuses is blown--the convergence chips got them-----

there are several ways to proceed from here-check the two fuses indicated in the photo and tell me if either or both are bad.

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.
