    I already open the TV casing and look for faulty component. No any blown fuse and any
    other visible burned components.
    Please start give me specific data which capacitor, resistor, or transistor is responsible for that effect.


  • idnelb Jan 13, 2009

    the projector is starting fine. after 5-10 sec. start coming bright, and then shutting down. My suggestion is high voltage problem, but i no have schematic. I need help from some one who have experience with this.

  • idnelb Jan 13, 2009

    the bulbs are working fine too. within 10 sec. i can go to some service mode and start align the picture (RGB bulbs is working there)

  • idnelb Jan 13, 2009

    Unfortunately I'm TV technician, and I need the specific information about just this mitsubishi projector

  • idnelb Jan 13, 2009

    Is maybe some one who know this

    mitsubishi vs-5051I found the C530 around Q501. The capacitor is broken, but i don't know the right parameter.



  • idnelb Jan 13, 2009

    I got still nothing. Please some one answer me so the C530 capacitor should resolve my problem or not. if not- what else i can do?

  • idnelb Jan 13, 2009

    the problem is : no have right value of this capacitor.

  • idnelb Jan 13, 2009

    The capacitor looks broken. I can't read nothing there



  • idnelb Jan 13, 2009

    I suspect the c530 capacitor, but i can't read his value.

  • idnelb Jan 13, 2009

    I can replace it, bat first i wanna now his right value (example: 220nF, 300pF). Maybe some one have directions or schematic for mitsubishi vs-5051?

  • idnelb Jan 13, 2009

    supply board ???

  • idnelb Jan 13, 2009

    is integrated on motherboard. maybe some closer.

  • idnelb Jan 13, 2009

    People stop write staff like "turn off and then back on" I,m no 5 years old...

  • idnelb Jan 13, 2009

    "chak the power capacitor from ckt bord its has been licy or bed"
    He looks like new, even i was tested by my ohm meter. work fine


  • idnelb Jan 13, 2009

    i just click for that link.
    does tot work

  • idnelb Jan 14, 2009

    technodeal - Your information was wrong. C530 value=33 nF not 220pF!!!! Why you give me wrong info?

  • idnelb Jan 14, 2009

    I already replaced c530 (right value is 33nF), but that does not help resolve my problem. Please someone who know that Mitsubishi vs-5051 for help me out.

  • idnelb Jan 14, 2009

    Ginko - thanks for that links. These works fine. I hope help me a lot.

Dear FixYa Customers Concerning HIGH END TV Repair especially REAR PROJECTION TV ,

I've had it with all the TV TECHS trying desperately to fix a lot of different HIGH END REAR PROJECTION and other HIGH END TV SYSTEMS!
Don't you all get it .......
THESE ARE SOME OF THE LARGEST MOST SOPHISTICATED COMPANIES IN THE WORLD AND I'D BET A LOT OF THEM GOT TOGETHER OR JUST DECIDED INDIVIDUALLY THAT TV SYSTEMS HAVE BEEN PERFECTED SO IF THEY'RE GOING TO SELL MORE IN THE FUTURE THE ONES THEY'VE SOLD MUST DIE OR COST ALMOST AS MUCH TO FIX AS TO BUY A NEWER IMPROVED ONE!
HAS ANYONE EVER SEEN A TV LAST MORE THAN 10 YEARS IN THE LAST DECADE? IF YOU HAVE I'D SURE LIKE A LIST OF THE MANUFACTURERS TO HELP ME SOLVE THIS PROBLEM! WE ALL NEED TO START TAKING PRIDE IN CREATING THINGS THAT DON'T BREAK AND STOP WORRYING BECAUSE THE NEW THINGS WE WILL CREATE WILL MAKE US BUY THEM ANYWAY UNLESS WE CAN'T AFFORD THEM BUT THEN AT LEAST WE WOULD STILL HAVE OUR PRIDE OF CRAFTSMANSHIP FROM BUILDING THINGS THAT DON'T BREAK!
I recommend buying the newest latest model if you can afford it or buying a cheap set while waiting for the price of the high end tvs to go down!

Ok a hard reset would be done by unplugging your tv set from the wall for about 4 hours after 4 hours plug it back on and turn it on,this not the problem that your tv set is having but you can try it,the problem would be coming from one of the pico fuses that are in the power supplycircuit,they look like resistors with a little bit of soldering experience you can change them it out,what i would suggest is to aquire the service manual for your tv set on the links below this will help you on where are the pico fuses and the rest of the fuses inside your tv set,remember to check the pico fuses for contunity one of them is causing this problem with your tv set,hope this helps.

Make sure your video input source is on and feeding power, and that the Mits is sourcing to that port.

Hi idneb
I think you will need to check the main power supply in the set. Most likely the regulator is bad because of bad capacitors (usually electrolytic over 100V . If you do not have any solid state printed circuit board repair experience, the best advice I can offer would be to call in a pro to assist you in this repair.
Thanks for using fixya. Good Luck.

    try changing the connection from being via HDMI to component video cable and analog audio cables if you can. (switch from coax cable to rca jacks)

    I don't know what capacitor number you have. Here is a link to the printout of your capacitors and the codes and paramaters. Just copy and paste in your browser. If not right one by chance then let me know and I will find another one.

    could be bad ballast, bad color wheel, or lamp/lamp timer. or lamp door.

  • Nate Stansfield
    Nate Stansfield Jan 29, 2009

    Check to see if your light bulb is lighting up. See if the bulb is good or not. Also, if you can, check to see if there is power coming out of the ballast with a voltmeter.
    The problem may also be the very common suffer from multiple dry soldered joints.

    To access them all, the main board needs to be removed from the plastic chassis and checked all over.

    Also, need to check the Tuner & I.F. board for same.

    Should be carried out only by a qualified engineer as it involves a
    fair bit of disturbance to the TV, removal of plug/socket connections
    and wire looms. Done loads of them and takes about an hour to complete
    properly.

    This could be in several different circuits in the tv. it could even be bad connections in the power supply, but, What I personally think is that It sounds like a problem with the backlight. These aren't replaceable,
    but the issue might be with the power to it. You'll have to get a
    repair shop to look at it.

    the part# is STK392-110 but most technicians including me replace these
    with STK392-150 for higher wattage rating and reliability. And before
    replacing these IC's technicians check small components called
    resistors and pico fuses. They also check for loose or cold solder
    connections.

The TV is not coming on because it has detected a problem and in in a protect mode. Since this problem appeared to clear itself before, I'd first look for bad solder connections on the board. Resolder any connections that appear grainy or have rings and try to start the set again. Post your results here. If not repaired, we'll start looking for conponent failures.

    This ususally means that the screen voltage is too high adn you are
    seeing the retrace lines. The only way to fix this is to turn down teh
    screen control on the flyback. This will make the picture darker
    though. I suspect that the CRTs are getting tired. Time for a new
    HDTV set.

  • mohammed marika thambi
    mohammed marika thambi Jan 17, 2009

    believe that you have 2 distinct issues with this set. First, the PIP
    module probably needs to have all of the capacitors replaced. Second,
    you have a high voltage problem. At this point the set is at least 15
    years old. Since the components required to repair this could easily
    exceed $100, is it worth it? Given that the set will require a
    converter next year (2008), I would recommedn that you replace the set
    with a newer one that will be compliant with digital broadcasts soon to
    be the standard.

    he is telling like this " disconnected everything and pushed the TV out from the wall so I could access the back. I removed about 10 hex screws and removed the fiberboard back. The inside of the set was incredibly dusty, so the first thing I did was attack it with some compressed air, trying to be careful to not blow dust onto the CRT gun lenses, the mirror, or the rear projection screen.

    t was pretty easy to find the solder pads for the STK392-110s, 18 pins in a row, one tilted at an odd angle. Luckily, most of the board was through-hole, but there were a smattering of surface mount components and the board was a bit flexible, so I worried that I would pop off a surface mount part. It didn't happen though. I used the soldering iron and the rubber desoldering bulb to remove the solder from the pins, then I reached behind and rocked the parts out of the holes. I had to re-heat a few of the pins to get them to release. Then I used some desoldering wick to clean up the pads.

There are many components that can cause the TV failing after ten fifteen minutes.

Start checking power adapter (PSU board) , that is an easy test if you are a repairman, and does not need diagrams.

Cehck also connector between power board and digital board(main board).

If the problem is not psu, then you need the service manual to follow the rest of troubleshooting diagrams, there are components on digital board, and on the small boards that control deflection, and power up Lamp/CRTs .

Do also a whack test, if tv turns off with vibration, then it is likely a cold solder joint, a broken contact, or a short to chassis.

If you are a technician all you need is the service manual, you can buy from here: Service Manual VS5051, VS5051C

    Thanks,

    it is difficult for me to follow your problem, as there is a little confusion with too many people trying to help, but it will be useful to know where the blown capacitor C530 was.

    If TV is turning off after 10 15 mins, test also the resistors at teh base of the STK ICs on the convergence circuits, the STKs are power amps, and if one of them is defective they can cause shut down when they warm up. When the problem is on convergence you may also get picture problems.

    Other circuits that can can cause shut down after some time are:

    power board, always the most likely when you get this.
    The small AC boards powering the CRTs (or the lamp on other models).
    Other problems on main board.

    I also checked on Euras system , that is a database for techs only, and sometimes sort out our problem ( EURAS)
    Many common faults that cause shutdown after complete power up on VS5051 and same chassis are caused by faults related to IC700 .

    I think you need to test pin 13, 15 and 55 on IC700, following instructions on service manual.

    I think test is the same as below, capacitors codes may be different, IC700 is the same.

    Here you find some common cause for shutdown after start on a model with same chassis. Power board and digital control board should be the same.

There is a problem within the horizontal circuit. This is not likely to be diagnosed without taking measurements inside the set. Invest in a detailed repair estimate and report the results here. We should be able to walk you through the actual repair.

Hi there!

This is more than likely due to the small signal board losing power.. If you have a service manual for the tv, you should be able to locate it. These tv's have been known to have bad solder joints from time to time, so it may be a problem cured by simply re-soldering the regulator that provides power to the small signal board. In the mitsu ws-65513 it is a ba09fp 9 volt regulator, it may be the same in yours. The regulators can be found at mouser.com. you can find a service manual that will have detailed troubleshooting information and schematics with part numbers here for $7.99
https://www.completeservicemanuals.com/mitsubishi/crt-projection-television/vs-5041-service-manual/prod_484.html

hope this information helps, and if you have more questions, let me know!

Hi and welcome to FixYa,

Offhand, a couple of idea you may want to consider:

  • a Mitsubishi VS-5051 is a 1994 PTV model using the VZ2 chassis;
  • a service manual would be to your advantage;
  • unfortunately not that easy for a VS-505;
  • may I suggest a VS-5041C, it uses the same chassis available here. for 7.99USD;
  • Included are schematics diagram.
Good luck and Thank you for using FixYa.

    Your initial post "Is working fine, but after 10-15 sec. the screen came black." but does the sound continue (normal)?

    If yes there is still sound, you could check the PIP board (if your version has got one). If there is, it would be the smallest board on the left side among those standing up boards. Try wiggling it and/or check for cold solder and/or the coupling capacitors.

    An update would be appreciated.

Check the Capacitor,, but i conclude the flash capacitor is the problem,, you cannot fix it by your self,, because you need to replace the capacitor!

    these are the common problem with that situation,,


    • Acoustic screen material allows speakers to be placed behind the screen

    • Relatively low cost for a motorized acoustic screen

    • Not practical unless the wall behind the screen is black or very dark and non-reflective

    • Screen surface is reasonably color neutral, although not as good as the best screens

    • Some loss of high frequencies, slight loss of overall volume of sound

    • Funky, but effective 12 volt trigger system, for having the screen drop at projector power up, and close on projector shutdown.

    • Comes with both infra-red, and RF remotes

    • 100", 16:9 version retails for $1609 before discounts, which can be significant on Elite screens.

    The black line you see running between the upper colors and the
    lower ones, is actually the bottom structure of the Elite screen.
    Therefore, the colors above the black bar, are those shining off the
    Elite, and the ones below the bar, are coming off of the Carada. As you
    can see from the image, each of the colors are almost identical. Using
    Photshop, I looked at the actual color composition (RGB) of each of the
    colors. I found overall, the Elite screen suffers a very, very slight
    shift to yellow/green in several of the colors, and overall (although
    the white itself measures a touch blue). The assumption here, is that
    the Carada is excellent in terms of color accuracy, and the Elite not
    far from the Carada's performance.

    The next image is another "split screen" with the Elite on top, and
    the Carada below. Since you are seeing different portions of the same
    image, it's a bit hard to truly ascertain how close to identical these
    two screens are. For that reason, the second image is the same frame,
    shown only on the Elite. You can now see the bottom of the face, and
    the tunic of our subject, on the Elite. Between the two photos, you can
    now see the same lower portion of the image on each screen:

Try to unplug the power first for few hours. If that didn't help, it will require you to open the TV casing and look for faulty component. Look for blown fuse and check the power supply board as well for any other visible burned components.

After all is said and done and u have spent or have an estimate for a $600-$800 repair bill u will be better off to replace the TV, new 42 inch LCD's are only $900, I have been through this scenario and the new TV is your best option.

The unit needs to be addressed by a pro. Too complicated unless you are a really strong appliance electrician. Good Luck

I need a picture tube for my mitsubishi vs-5051 40in projection tv, how much do they generally cost? whats a good website or store in my area of manor texas?


Honestly, sorry to give you the bad news and I'm one for trying to repair then throw out but, buy a new 42" flat panel it will be a lot cheaper. Mitsubishi quite making these size CRT's over 5 years ago and a replacement tube would cost more than buying a new replacement 42" TV.
My thoughts is that this 5051 is over 13 years old.

I can help you here follw my pictures and be sure you have a reciever hooked up so the TV can identify it.In some cases like in picture #2 you have to tell the TV that its on by entering it in your self ,(notice the pic.2 Ive selected NO on right side ) you have to use the Volume /Enter keys to make the change,and you probably already learned that you have to highlite each move your at that your changing.d116022.jpg9f9fa1f.jpg

Is the power light staying on? If so press imput and menu together for 5 seconds to see if the set will blink a 2 digit repeating code. If that doesnt work. Check for CRT coolant leaks on the boards. This seems to happen alot as do faulty capacitors. Coolant leaks will be located on the chassis directly under the tubes they can cause corrosion and prevent your set from starting especially in the VS models.

Mitsubishi vs 5051 rear projection tv sound but no picture


No video but good audio Mitsubishi VS5051. Check R509 and R 519, 100 ohm resistors located on the main PCB near the flyback transformer. Also bad connections on any of the yokes and the vertical output IC will cause the same problem.

First you can safely take off back and look for Screen controls&Focus, Gently turn up the 3 screen controls this will add light to picture, but you need to evenly turn up, the 3 colors are red, blue, green. the other 3 knobs are for focus. Do not turn them if you do you will need to realign the focus also. And if this doesn't help then there is a high voltage capacitor leaky in the flyback area.
