Top 20 Mitsubishi VS-5043 50" Rear Projection Television - Page 2 Questions & Answers

There are a few low value 1-watt flameproof resistors in the convergence yoke circuits. They typically range from 1 to 3 ohms. An open resistor will cause the respective color to be non-responsive. Also chack that you have the convergence yokes re-connected to the correct connectors on the board.

more than likely, your tv has been bumped with just enough force to offset the calibration of the guns. you will most likely need to take this to an expert in order to have it re-adjusted. if it is minor and something you can live with feel free to ignore it, otherwise, like i said, take it in. it is not something a non professional can handle as adjustment is very precise and requires access to the inner part of the TV. never open a TV unless you know what you are doing unless you want to risk death by electrocution. even when powered off, the TV set still contains lethal amounts of electricity.

there is a optic coupling between the tubes and the lenses
it however is not mineral oil
and the fluid that is between the lenses is poisenus
so be careful how its handled

its a glycol base mixture and it doesnt have to be changed every couple years
some brands do seem to have a problem with it but Mitsubishi did not

cleaning the mirror and lenses of course will help give the best picture
i have never changed the fluid in a Mtsubishi unless the tube was leaking
its not recomended

just go to mits site and download the manual. i have a mits too and your manual is there. just use all info u have to search.

What you might be experiencing based on your symptom sounds like a damaged convergence IC.

With any Projection Television that has a damaged convergence IC, you do not want to continue the use of the set. If the IC’s continue to fail they will cause a short in the power supply and cause your television to not power up, and possibly damage the CRT’s in the set.

With that aside I have some support suggestions that I have put together that may help you make an informed decision.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.


I hope this information allows you to resolve this issue.

I have attached some photos of really bad convergence problems; your picture may not be exactly as bad as these.

check first for the contact point of your control panel button maybe the tact switch is shoted specially when your always using remote control for function operation.second check power supply for leak capacitor or change in value,check also the photo coupler for leak test or change in actual.

Ur Horizontal/Vertical ic stablizer is dead or it supporting componnents.90% is ur IC.

Its a convergence problem. You may want to check the site www.tvrepairkits.com. Every thing they said every description was right on. The best money I ever spent and the confidence you get from doing it yourself, Its a great feeling of achievement not to forget the live messenger support is instantaneous, friendly and informative if you need to fix your tv go to tvrepairkits.com I fixed a philips 60 inch tv in 45 minutes, The convergecne chips were bad thanks a million. You guys saved me 250.00 bucks. I'll be recommending you to everyone I know!

The CRTs contain coolant which is most likely what leaked as thats the only liguid inside the television.

If you go into the main menue with the Mitsubishi remote, there should be a set up icon for programing stations. It should give you a selection for cable and or standard tuning. Select cable then press auto program.
Hope this got it done,

ur Power ic inverter board is dead.
u need a new one.

two big chips on one seprate pc board
sk_ _ _ _ _ _ ? get the number google it
cost about 10.00- 20.00 etch order them
go to raido shack get solder soldering iron
40watts and solder braid (whicket)
remove the solder pull the chips ,one
small screw holds them to the heat sink
replace with ordered parts set up
covergance Done. you just saved 300.00

bad convergence ic , stk392-110

I just signed up and picked an unusual nickname. I found STRM6811 had a short from drain to source once removed from circuit. It has seven leads and is mounted to a heatsink near the input fuse. I called around and found a used one just up the street and I only paid $3 for it. All good for now!

I have the vs-45609. goes blank every once in awhile. maybe you can use it for parts for yours? in texas

Try what I said for my solution. At most you will have to order the part online and wait for 3-5 days for delivery.

on your control you should have a sleep button press it until it says sleep timer off.

I had that problem 2 years ago but I don't remember the odor. The solder connections came loose on the red tube's small pc board. The wifes make-up mirror came in handy to resolder the loose wires.
