I believe you have an overheating problem. Unplug your set and go to the back, make shire all dust is free from the cooling holes. This should fix your problem. If not pull a little further from thevwall and put a personal fan blowing on the back. Hope this helps.

Hi,

This is a short protect error code. The affected parts is not only the pico fuses but also the convergence IC(STK393-110) that is mounted on the large aluminum heat sink. I have a link where you can buy the repair kit that includes steps-by-steps instructions that will guide you in the whole process of repair. Click the link below.

Have a nice day!
Thanks for using Fixya.

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 wires coming from the front keyboard of theset---remove the inspection plate and follow the wires to the right--you canunplug both plugs(most have two and they are marked with letters and differents 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.

If the attached photos look anything like your problem it is a convergence problem.

This can be a do it your self repair if you have some skills and I have start to finish and step by step instructions for this; they tell you everything you will need and how to do the fix.

Before you rate this information let me know what you find.

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

Hi,
It has a bad resistors on the convergence circuitry. Check the resistors around the chip using the multimeter. If the resistors are color coded, click this LINK to determine its value.

Thats a very common problem caused by failed capacitors on the DNM power board. Repalcing them should solve the issue. You can get the DM repair kit for your model at www.tvrepairworld.com which contains the upgraded caps and the CD with repair instructions

This TV uses either a single STK-393-100
or a pair of STK-392-570's

the only way to tell is to look inside.
unplug the unit and take off the back.
the convergence chip(s) is on the center board on the big finned heat sink.

This fault LEDS indicates the switched mode power supply has gone into protection mode.Unfortunately it does NOT indicate the exact place or nature of the failure, only that it has, failed.

This is a fairly classic switchmode power supply problem. The protection circuitry inside the SMPSU, has sensed a severe potential problem, and is attempting the shutting of the set, down to avoid a fire, explosion, or both.
This set had developed a problem, that is so severe that the set must be shut down, (This set should be removed from the Power),
What is happening is the internal "Fault" that is causing the Protection Circuitry , to detect the problem and attempt to shut down the set, sometimes a set keeps restarting the set, because as soon as it shuts down, the "Faulty" component(s) cool down?, and the "Fault" ostensibly "Clears" so the PSU starts up again, only for the component(s) to heat up, whatever, again and fail, so it shuts down, and if left unattended, this would continue on until the part eventually failed. as it appears to have done in your instance.. Any fault that involves the power supply is usually quite serious, and needs a professional, usually, unless one is familiar with servicing current day, televisions.
And in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center. Now, this point is very important for a good result, Always contact, their "Local" or a, "Head Office" Mitsubishi in your case. Ask them, for a referral to an authorised servicing center, where you ask for a "Quote". Now, when you get the information you want, then you can decide as to repair of replacement.
The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done.



OK well what has happened i suspect, is that your set has been "Spiked" from a power disturbance, and this has damaged either the PSU, or an internal high voltage component, or both, and now, the Protection Circuitry in the SMPS unit, is "Sensing" a potential "Catastrophic fault", that may cause a fire an explosion or both, and accordingly the set MUST be shut down, so the protection circuitry does exactly that.
Your best bet, is to contact a local or head office of the TV's manufacturer, and ask them for a referral to an authorised servicing center. When contact is made with them, ask for a "Quote" for the repair, before allowing any repair work to be undertaken. This then at least will give you an idea as to costings and you can then make an informed decision as to repair or replace, as often these days i find in my shop anyway, many repairs can be very expensive, and often it would be better putting any monies that would have been spent on repair towards a NEW unit with a warranty.

xazna,

There are no DM boards available but there are repair kits for the board. I have a tip at http://www.fixya.com/support/r7065906-mitsubishi_turn_flashing_power_timer which explains where you can get the parts.

Thanks for using FixYa and for the great rating.

Do you get a flashing green led? Or is there nothing going on at all?

There are 4 capacitors in your DM Module that have been known to go bad. They are located in the metal box that is on the left side of the set looking at it from the back. The capacitors can be changed with relative ease, but if you don't have any experiance in electronics, I would advise that you have an service provider do it for you.

Sounds like a convergence problem. See if you can adjust the customer convergence controls (in the menu).
If you can not adjust one or both the colors than your convergence amp is toast!

The Bulb in the unit needs to be replaced. To confirm, look in the manual for the set and it will explain the flashing lights by the numer and duration of flashes. Hope this helps.

Hello

After you set the lock, you need your passcode

to view a V-Chip locked program, view the

locked TV, cancel the lock, or enter the V-Chip

Lock menus.

If you forget your passcode, you can view the

locked TV without entering your passcode.

This is done by pressing the number 9 and QV

buttons on the remote TV control at the same

time, when your passcode is requested. This

process temporarily unlocks the TV.

When entering the V-Chip Lock menu, this

process deletes your old passcode and prompts

you to enter a new passcode. Pressing HOME
at this time will cancel the entire passcode.

Bypassing Front Button Lock

If you have misplaced the remote control, you

can bypass the front button lock by pressing and

holding the MENU button on the front panel for
more than 8 seconds.
OK.

This is typical with many sets when it goes old as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.

Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Please find below two links for tips on poor start ups, as if the set is totally failed the SMPS might be faulty

I used to have a WS55909 and had this problem. The light is supposed to blink for one minute while the DM (digital module) boots up after a power loss. If the light continues to blink indefinitely, there is a problem with that board. The DM power supplies are known to have faulty capacitors on these models and will need to be replaced. If I remember correctly, there are (7) 1000uf 25v capacitors and they should be desoldered from the board and replaced with 35v ones. Note that my TV model already had 35v caps but changing them solved the problem: electrolytic capacitors have a much shorter life than other components.
The DM is on the left side and is where ANT-DTV and the IR repeaters plug in. The power supply is the board above the main DM board inside the DM case.
If this sounds too technical for you, get a new TV because a repair guy will charge you more than the TV is worth. In other words you could get a (30-46") LCD TV for the same price.

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.
