    It doesn't seem to be putting the lines further of center and the convergence is less noticeable with the color lessened on the picture. Is it impossible for me to access the service menu? And so are you suggesting I call a tv repair service to have them replace the ICs?

How far off are the colors misaligned such that you need to enter the service mode to fox them? If one or more of your colors has taken a dramatic shift in position, especially on any edge, then do not attempt to correct through the menu. If one of your convergence IC's has failed then the colors will not align on the screen. If you try to correct this in the menu, you will only be screwing up all the settings and making the set worse. When the IC is replaced with a new one your colors will still be way off, not because the new IC is not working, but because now the menu settings are too far off. I have been to many houses and spent 45 minutes replacing a burned out convergence IC followed by more than an hour realigning everything the customer messed up.

    If you cannot align the convergence using the regular menu, it usually means that something is very wrong in the convergence circuits, usually a burned out IC. If you access the service mode and do not know exactly what you are doing, it is possible that you will completely screw the set up. The convergence circuits should be serviced and realigned by a tech experienced with Mitsubishi projection TV's.

Mitsubishi VS-50803 Big Screen TV - Trying to hook up an HDTV cable box, I was told to hit: menu, 1, 3, 7, 0 - to get to the service menu and switch DTV over to HD and that would solve my no signal...

First please confirm actual model number on rear of set.

Something is not right here, I am looking at Mitsubishi material downloaded in my computer; shows all codes for sets up to 2004. VS-50803 is a VZ6 Chassis made in 1998 and I doubt it is HD set, if it is one of the early ones it will have beneath the HD input vert sync and Horz sync---those required a special box from Mitsubishi etc.

Set has 3 hidden menus:
1. Option menu (for hard reset)= Menu 1,3,7,0 enter
2. Circuit adjust menu= Menu 2,3,5,7 enter
3. Convergence adjust menu= Menu, 2,3,5,9,enter (#4,5,6 on remote then change modes)

Does the DTV input have the two vert, horz jacks as well?

First is the Option menu is really only for a hard reset of the entire set, if you engaged it you may have de-converged the set.

The adjust menu is for height, width etc

The convergence menu is for convergence.

If you did something and did not save it, unplugging set should put it back to before what you did.

I have a mitusbishi ws-a65 hd 1080 tv. im having trouble getting the picture to line up with the shodows, its showing double, how can i fix this?

Your Convergence ICs have likely failed. It is very common on rear projections. Replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu.

Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option to align the red and blue colors

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.

Note if one STK chip fails, you replace both regardless. There may only be one STK chip in this set. If there are two, they will be right next to each other.

The word "Factory" has appeared on the screen in red


Factory on screen means that the TV is stuck in service mode (Durabrand and more). The problem is fixed accessing Service mode and resetting to factory default settings.
On Durabrand TVs problem is fixed using a programmable remote, entering service code on remote, and accessing service menu.
Procedure is listed on TV service manual.Most durabrand use Menu and key combination 683 to access service mode.
If that does not work, calll manufacturer number to get the key sequence to enter factory menu.

Mitsubishi WS65809 HD input (DTV) not working correctly. I replace the convergence chips in this TV and was making adjustments in the service menu. Everything was lined up and working great. The HD input...

All these sets do have a hard reset---not the reset button on the front of the set---it will return the set to the factory original condition it was when new in the box--it will not affect the convergence as that is stored in a separate unit--the DCU (digital convergence unit).

It is accessed with an original MITSUBISHI remote.

You can try it if you want:


menu-0,1,7,0 enter

There are 3 hidden menus in the set--this is the Option menu

You will see either reset or option etc and highlight it with the remote and hit enter. Set will shut off and should come back on channel three in the air band--any labels you placed on inputs will be gone and set will be in air band--you will if on cable have to change it to cable band and auto program etc.

Let me know what happens and if you have questions I am here to help.

Can't loate bool;et for Mitsubishi HD 1080 Series Medallion

it is usually in the Audio settings,sometimes by the CC settings, if you go to the TV and enter th menu from the set, go thru one at a time until you find the spot to turn it off, it is under options or Menu on the remote also, there maybe an SAP Option on the remote itself, but you may have to press another key first like a "Function: Key.
I hope this helps some, if so please give me a good (fixya) rating. Thanks and have a Blessed Day

I cant get high def 1080-i to work on my mitsubishi 55807

IYou have to have your comcast box tuned to a channel that is broadcast in HD. On your Comcast remote hit menu. This will bring up several icons, one is HD. Select that icon and it will bring up the TV Guide for just HD channels. Select one and tune to that channel. Once your on that channel use your original remote and hit menu, then advance features, then go down to video display and change it from 480 to 980 or 1080. Let me know if this helps.
