Top 20 Mitsubishi WS-65909 65" Rear Projection Television Questions & Answers

Sounds like an issue with the DM pcb. most likely some small electrolytic capacitors. you will need to remove DM pcb & take cover off. look for capacitors with bulging tops. note the values & location & replace all capacitors with bulging tops.

POWER SUPPLY BOARD. FIND HONEST TV TECH. MAY RUN AS HIGH AS $300-$400 REPAIR. A EXCELLENT TV

Thats the code which normally indicates a convergence failure you can get the WS55909 - WS65909 Convergence repair kit which also has instructions from www.tvrepairworld.com its listed under the Mitsubishi repair kits catagory.

Pincussion or convergence problem. Look in the menu for convergence and call up the advanced grid.

if can not get with manual adjustment in the set up menu, then you have problem either the convergence ic get bad or the resistor get an open resistance.

If you get the 2,2 error code that is short protectionIf you get the 2,1 error code that is X-ray protectionThe 2,2 is most common and the easier one to fix.If in doubt--unplug set and plug back in and try to turn on, when power light goes out do the self check again (unplug clears the error codes)let me know actual code found and I will help---hope it is 2,2.

You have come to the right person:all parts in this model for the convergence are located on middle board.If set comes on and shuts off (green power light goes out) do the self check: press and hold (you may know or have done this) both the menu and input buttons for at least 5 seconds and release both.Power light will blink a 2 digit error code like 2 blinks, 2 blinks a pause and repeat it several times.That is short protect and a 98% chance one or both (usually one) of the two pico fuses that protect the convergence circuit have blown.I will add some photos here one of the single IC this set uses for this, one of the protect resistors in front and to one side of it, and one showing the pico fuses (ones for the chip are circled) A note= I have fixed a lot of these and have composed instructions which are based on doing it---tell you everything you will need and how to do the repair from start to finish--step by step.I will not post them here as other experts will copy them and I spent some real time composing them.If you want they are free--provide me a email address and I will forward them to you for free.I have fixed almost a thousand of these sets (Mitsubishi) with this problem.Copy and save the photos and let me know (you can post a comment here) if you have questions or want the instructions.SD TECH the photo for the fuses will not load---on middle board to left and towards the rear--green and location numbers 9fao4 and 05--both are marked 5 amp,.

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

This model uses a single convergence chip that after age fails.I will attach some photos of the part, and also typical convergence problems.The repair can be a do it yourself job if someone can solder etc.The suspect part if it is a convergence problem is a SKT393-110(ABOUT A 15 DOLLAR PART ON EBAY).If you are able I have start to finish step by step instructions for this repair that tell you everything you will need and how to do the repair.Look at the photos and let me know.sd tech This is the part if it is a convergence problem.No two sets will look exactly the same but the photos should tell you if it is a convergence trouble or not.Steve

Did your check your horizontal output of the crt neat the flyback or high voltage transformer.

Usually a power outage causes this

hi,
Your tv have problem with Digital module DM board. there seven filter capacitors (1000uf 16V ) in the DM board. if any one of it is faulty the this problem can occur. its a regular complaint for this model. just replace the capacitor. i have added the picture of the DM board you have to replace the marked capacitors . Also check the two fuses in the same board 4Amps fuse and 2Amps fuse.


ok

If it looks 3D or warped it sounds like your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

I am a proud owner of the same TV you have. A couple of months ago, we had repeated, intentional rolling power outages in the Dallas area in an ice storm. I had the blinking green light of death also. The problem is in your DM module. If you remove the back panel on the set and expose the boards, the DM is the one farthest to the left. It is actually located inside a metal frame that surrounds it. You can disconnect the wiring harnesses coming out of it to the other boards. You may have to label the harnesses, but typically they are labeled so you can simply match the numbers of the harness removed to the receptacle into which it was originally plugged. There should be about 5 of these to remove. I recommend using needle-nose pliers, as they can be very hard to unplug. Just don't squeeze too hard and crack the plastic.
Once you have disconnected and removed the DM board assembly, you will need to remove the metal housing and disconnect another series of wiring terminals in order to fully expose the power boards within. Make sure you keep track of which screws go where, as some may be longer than others. Phone pics of wiring harnesses can come in handy so you remember where they go. After the metal housing is removed, you will see an elevated, smaller board attached to the much larger main board. The small PC board needs to be separated and removed so you can hold it in your hands and work on it. At this point, you have the option to take the board to an electronics repair shop or to fix the problem yourself (as I did) and save yourself some money. A decent repair shop should remove and replace the defective components for about $20, PARTS INCLUDED!. There are 7 capacitors that need to be replaced. They cost less than 50 cents apiece at an electronics parts supply shop. You may find them at RadioShack, but I recommend an electronics supply shop. This way you can buy capacitors that have a higher voltage rating than those originally installed. A higher voltage rating is recommended and will in no way affect performance or outcome. In fact, the original caps (capacitors) were rated too low in terms of both voltage and temperature. I believe the original caps were 1000 uf (microfarad), 16-volt caps which are black in color - indicating they are 85 degree compliant. Look for 1000 uf (microfarad) capacitors with a brown color that indicates they are better for high-temp applications of up to 105 degrees. You will be able to clearly see on the cap that it is 1000 uf, 25 v, 105 degrees C. One very important thing to note is that a defective cap isn't always obvious and will NOT always display symptoms of a bad cap. Typically a bad cap will have an outward bulge on the top, like a soda can about to explode. It may also show signs of dark, caramel or black colored syrup-like liquid oozing out of it. This should be considered, but definitely not ignored. When I fixed my set, ALL of the seven replaced caps actually looked like they were brand new and showed NO typical signs of fatigue or failure. I replaced all seven anyhow, put it all back together, and brought it back to life and saved myself many hundreds of dollars. The primary point I wish to relay is that you do not rely on the apparent physical appearance of the caps to decide their state. I hope this helps any and all with the symptoms related to the constant blinking green light which responds to nothing on the Mitsubishi WS -65909. You CAN save your TV by spending less than $75 by doing it yourself (less than $15 if you have a soldering iron and solder) or take it to a ****** who won't do component-level repairs and will just replace the whole DM board for 700 bucks or so. I know these sets are old and rapidly being replaced by LED, Plasma, and LCD sets, but you can't beat the pic for the price. If I get enough requests, I will figure out how to post a video how to to do the whole thing. I hope this helps. This will fix the constant blinking green light with no power-up on the Mitsubishi WS-65909 rear-projection TV!

You can check the Error code by doing the following.

On the Front panel hold down the Device and Menu Button for 5 seconds. The LED light will then start flashing the first set of flashing lights is for the "1"5 part of the code it will then pause for about a half second and start the ones place 1"5". The code will repeat 5 times before going off.

The Error Codes: 12 - Normal Operation; 21 - X-Ray Protect; 22 - Short Protect; 23 - Loss of Horizontal Deflection; 24 - Loss of Vertical Deflection.

The problem may also be in the power supply when you first plug the device in check how many times the Led blinks if it blinks for just over a minute the power supply is working fine. If the Led blinks repeatedly and does not stop the DM is not running.
This is a link to the service manual for you TV, http://www.service-manual.eu/model.php?id=2710

The easy way is to call mitsubishi with the model number or I can look it up for you------------this model has a Hard reset done with the original remote to reset the set to the condition it was when new in the box--this will return the option to turn the speakers back on (THEY WILL BE GRAYED OUT IN THE MENU IF THIS IS THE CASE).

confirm actual model number!

Hi.

If the TV stays in stand-by, with the LED light on and flashing, but does not respond to remote, or to the buttons on the chassis, then the TV is in protect (safe) mode because an internal fault had been detected. In this case the fault is not necessary the PSU. Parts must be tested to find out. The clicking sound is the protection circuit that keeps turning off the PSU to prevent further damage.
If the problem is the PSU, often it is possible to see at a glance that one of the big electrolytic capacitors in PSU board has blown.

General troubleshooting on this article: Why my TV does not start up and remains in... .

This will not help in case there is effectively an internal fault, but can reset the fault mode if the error was prompted because of a temporary problem.

If that does not work, contact the manufacturer at the number listed on the owners manual to get the TV repaired by a licensed technician.

Note if the TV is blinking a number of times, then there is an error code. In that case report the error code and I will tell you more on the problem. I answer within 4 hours.

Regards.

Ginko.

toctallent,

The DM board is located in the sheilded box to the left side of the unit looking from the rear. You have to disassemble most of the unit to get to it. I have a tip at http://www.fixya.com/support/r7065906-mitsubishi_turn_flashing_power_timer which explains the problem and where to get a board repair kit to repair the unit. The same company has excellent installation instructions.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.
