Mitsubishi WS65513 Blinking Green Light

As I have read, the capacitors go bad from the inside out because of the high frequency of the power supply and there is excessive ripple in the B+. I have heard also that if they had of used high frequency longer life type capacitors, this problem would not be so widespread. It is also not if the capacitors will fail, it is WHEN? In my opinion, every Mitsubishi TV set that uses the DM will have these capacitors fail at one time or another unless they replaced them with the better capacitors.

Hi all,

I am new here but like most of you, I have a problem with my Mitsu TV. I have the WS65869 that has come off the extended warranty within the last 6 months and of course now it will not work. The symptoms are that the TV will turn on for a few seconds, show a blue screen with white lines that look like a bowtie and then it shuts off by itself.

Could this be the same issue as the "Blinking Green Light" issue?

Any help would be appreciated.

Thanks..

Nope, sorry not the same issue. You have a bad convergence IC's They will need to be replaced and then check F9A04 and F9A05. Do not replace those fuses without replacing the IC's first or you will cause more harm to the TV set. Good Luck

Thanks for the quick answer Larry.  Isthis something that I can do myself or do I need to contact a service provider?

Thanks..

First off Larry let me say you pics and instruction were dead on.  I watched the repair guy do the job and it was text book.  Now I'll share some information.  It appears that Mitsubishi knows about this problem.  About 1 year ago they sent a bulletin to all licensed repair facilities informing them of the "fix" and that they needed to use a 680MF 16V capacitors instead of the factory 1000MF 16V.  This fix was discovered as a result of the fact that Mitsubishi ran out of the DM boards which were initially thought to be the problem.  As DM boards can only be obtained and installed by a repair facility, it became necessary for Mitsu to offer up the "fix" since they were back ordered on the DM boards.  Hence the issuance of the bulletin. 

To say the least Mitsubishi has some explaining to do.  I'll let you know the outcome.

BTW - repairs were $364.58

openseason, really depends on if you can repair and solder on printed circuit boards. If you can the job is not all that hard.  If you have no printed circuit repair experience, I highly advise that you call in a tech to assist you in this repair.

Curt, that's good. But charging 365 bucks for less then two bucks worth of capacitors on a fault that is their fault is still way too much in my book.

Regardless of whos fault it is that is a rip off. Thats about 200 bucks an hour if even

JWA

No question there.  I just sent Mitsu a letter, invoice and proof of purchase.  They said they will let me know in 2-3 days.  I can't hold my breath that long but I am curious what there response will be.

Thanks Larry.  I found some friends that have solderede before so I will take the board to them.  Do you have a schematic/service manual of the WS65896 that could help me identify the convergence IC's?  My email address is [email protected]

You have been a tremendous help.

Thanks in advance.

I totally agree JWA, I would also complain to Mitsubishi about their own service company ripping you off like that! I would be interested in what they had to say about this though. Probably give you a token gift certificate like RCA did several years ago for a common fault that showed up in almost everyone of their TV sets. BUT you had to use the 50 bucks towards something from RCA over 100 bucks.

openseason, you have given me two different model numbers. Which one is it? Look at the back of the set please to be sure.

Sorry. Fatfingered that one. The model for my TV is WS65869.

Thanks..

Larry Dillon said: If you are handy, and can solder, you may be able to save about 700 bucks if not more. There is a very common problem with these Mitsubishi TV sets. There is a digital board inside these puppies called the DM board. A lot of times there are four capacitors that go bad inside of these TV sets. Sometimes, depending on how bad the capacitors are, and if the capacitors did not blow out anything else on the Dm board, you can simply replace these four capacitors and this will fix your TV set. The average that this works on is about 65 to 70 % of the sets can be repaired with this fix. The others are power supply issues or the DM board has other issues. If you would like to attempt to repair your TV set, I will send you the instructions on how to do so.  If you do not know how to solder well, do not attempt to replace the capacitors yourself. Pay a pro to do this for you. After all you are already saving a bundle of cash. Leave an e-mail address, and I will forward you the fix with and without the light engine. And if the capacitors inside the board are not swollen on the tops, as the direction shows you what they look like, change the capcitors anyway. I have had a few that looked good but the capacitors were on their way out. Good Luck

Larry,

I am having the same problem with my Mitsubishi WS-55813.  Could you send me the instructions also?

Larry Dillon said: I sent these documents to you. If though you have no experience doing any soldering or repairing printed circuit boards, play it safe and take the board and the capacitors to a pro. this fix works on about 65 to 70% of the peeps who have this problem. Good Luck

Larry you seem to be the savior when it come to the good ole 65" Mitsubishi. I unfortunately have had the same problem with my tv.  I'm in Sat. communications and have done more than my fair share of fixing and soldering on many components, but for some reason I've been nervous about opening up my tv. If you could send me the Same documentation I would greatly appreciate it.  Also will I be in a position to clean the lenses when I have this open? IT's been 2 years since I have had that done and would like to learn how to do it my self, so if there is any information on that that you could send me I would greatly appreciate it !!

Thank you

OK cool man. I know what the thread is list as but there are a lot of people that post for the info only to respond to me that I sent the wrong model number info. I will have that to you very shortly. As far as cleaning, it is very easy. I will be sending along the factory service manual along with the DM repair documents so you can see in the manual how the front screen comes off so you can clean the mirrors and lens. A lot of times, a simple cleaning makes a world of difference on the picture. Good Luck with the repair.

larry,

I have the same problem with the blinking light WS65613 i did a visual check of the caps and didnt see any obivous problems such as burned spots or bubbles. I wouls like to change these and see if thaqt fixs my problem cause its a common fix for this set. A TV repair person told me the problem was with part# mit 275p942020 and m306v3mg-803fp. But after reading the comments on here im very suspect of that dianosis. Can you please send me the service manual and other info need to make repairs to this tv. Thank alot!! [email protected]

I do not see those parts coming up in the parts list. I will send you the documents and the service manual. the caps could be bad even if they do not look swollen. Good Luck

Larry, 

I realise you must be tired of sending this info out to everybody. I would appreciate it very much though if you could send the instructions and service manual for that WS-65813.

Larry

Thanks for the info it fixed the problem

Brian

Brian, So glad it worked for you man. Happy to assist. Just do not forget to follow the service manual you received and see how the front screen comes a part and clean the mirror as well asd the three lenes.  

Larry,

My Mitsu WS-65813 is having the same problem everyone else is describing here - blinking green light that does not shut off.  

Any info you could pass along regarding getting to the DM module and replacing the caps inside would be greatly appreciated!

Mike and Rob, I have sent out the repair guide as well as the service manual to you so you can repair your TV set. Good Luck with the repair.

Hey Larry,

I was wondering if you had the chance to send out the repair guide as well as the service manual for my TV.  Earlier I mistyped and gave you two different model numbers.  The correct model number is WS65869.  My email address is [email protected]

 Thank you very much for the service that you provide here.

Tae, I thought I sent that info to you. I will send it out again to you. Good Luck man!

Larry, I've got a WS-55513 with this blinking green light problem.  Can I get a copy of this manual

[email protected] thanks

Larry,

I am looking at the schematic and I just want to verify the parts number for the convergence IC's.  The part number that I see is IC800.  Do I have to replace IC8C01 as well?

Thanks..
