Check the CC (closed caption) settings.
You may have the closed caption turned on, it may be set on text or a setting that is causing this. Turn CC off and see if it goes away. If you need the CC put it on a different setting.

Hi gomeryandgee,
If the symptom didn't cure by convergence
adjustment through the remote control, this is an
indication of faulty convergence board inside. You may replace
the convergence IC's and some of the resistor around because its already gone bad http://www.tvrepairworld.com/mitsubishi_repair_kits.
You may also replace the entire convergence board for your convenient. If the
board replaced with new one, your unit will back to normal again. Also, consider bad solder joints in that area,
it will do the same symptom like what you've encountered right now. Find it first
and re-solder. If you
don't have necessary tools and
test instrument and can't do
the job yourself, I would advice you to look for a qualified technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

You have several bad grounds in the convergence board. This TV will also need a new convergence IC. I believe it is a STK 393-110. It has poor grounds on its pins to the circuit board. I would suggest you replace it with a new one, it would be heart breaking to resolder the original IC and discover it is bad. It takes quite a while to pull this board out and replace. Be sure to check the 2 watt less than 10 watt resistors too. They can be bad. And I cannot tell you enough...there are also many,many bad grounds through out this convergence board. Please really examine this closely. Solder any and all ICs attached to heat sinks, power resistors, transistors, transformers etc. This TV is worth repairing. Thanks for asking and show a few hands of support!

It sounds like you have a faulty power supply. These go out on most televisions after a period of time and use. The repair is going to run you about 200-300 dollars, and you can actually have a repairman come out to do the repair.
The set will turn on but not stay on. The green
Your TV is going into immediate shutdown. The first thing to determine is whether you have liquid coolant leakage from any of the pix tubes, usually the blue. Remove front spkr grill and six screws from front door panel. Look very closely inside on the green colored PC board for any liquid or residue. If you don't have leakage of any kind, then most likely a convergence output IC problem in which case you'll need an experienced servicer. Good luck

Press the Windows key + P on your laptop.
Or, if that doesn't work, look on your F keys for something that looks similar to a monitor.
Press the FN key and that key.
This should bring up your laptop's display on the tv.

The WS-65809 uses two of the STK-392-570 convergence IC's---if convergence is skewed and will not adjust----both chips and any of the protect resistors around them that are bad need to be replaced.
The repair involves getting the middle circuit board out of the set---You can buy a pair of the chips on Ebay for less than 14 dollars plus shipping.
This all depends on if you are handy and know how to solder----each chip has about 18 pins that are soldered in-----I repaired one of these here yesterday for someone---repair takes about one hour.
If you are able to do it yourself you will save a lot of money as most shops charge 300-400 for this type of repair. If you get someone to do it for you make sure they change BOTH chips---
I have had so many people here ask me how do this repair that I have composed start to finish step by step instructions for this set---they tell you everything you will need to do the repair---if you decide you want the instructions let me know and I will post them here for you.
Not everyone can do the repair---

TV will not turn on seems to not have power.
If the TV "seems to not have power" then I assume that no lights are on or blinking, and that no noise is made by the television at all. This is most likely a power supply issue or a power chip issue. If you know anyone who able to solder or has working knowledge of electronics boards this could be a relatively cheap fix ($30+ in parts). Otherwise, you may be paying hundreds from a TV repair shop.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.

How do i hook up
Your television has component inputs. You need an up-scaling DVD player or another source that uses component cables and will have an output of 1080i (your televisions max resolution)

Sounds like you have a cooling issue. Do you notice if the fans inside the back of the tv are running? If not then it's overheating and turning itself off to prevent further damage.
Also The next time it happens, before you just turn it back on, press the INPUT and MENU buttons on the front panel together and hold them down for at least 6 seconds. This should cause the front LED to flash a 2 digit code. If it flashes once, then twice, then pauses and repeats, it means that the TV's computer didn't detect a problem.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
- Screen looks 3D
- Colors don't line up
- One or more colors can't be adjusted when using the convergence menu.
- Screen is bowed or warped.
- TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.
SOLUTION #1

Common Problem #2) CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Tv is showing double images,
Your Convergence ICs have failed. 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.
On my HD1080 Mitsubishi projection
You have poor contacts and or dry joints. Resoldering on the convergeance panel and powersupply/line timebase board will probably fix it.
It should take less than an hour in labour terms.
After having our tv in storage for aver a year,
Not sure I understand what you mean by green shadow. I would check the fluid in the green and blue CRTS and verify they are clear. I would do this if the green color seemed fuzzy or blotchy looking on the screen.
When looking on a blank screen, do you see any arc lines of either green, blue or red? If so, you would need to lower the screen voltage for that particular CRT.

i have a question
Ok, explain somethings to me. Which parts did you replace? 3.9 ohm resistors will read about 2.2 ohm in board, they are in pairs.
Was convergence problem different than before or EXACTLY they same?

I have this exact TV.
ONLY 1 of 2 things can cause this problem----It is commonly called the blinking light of death.
First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---
Notice the one or two pairs of wires coming from the front keyboard of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)
The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---
These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.
If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.
If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---
You can call them and get a quote for repairing the receiver.
