TV shuts off ?

Tv shuts off as soon as its turned on.Also known as instant shut off problem.this was very much noticed on Mitsubishi brands TV.


Most of the Mitsubishi rear projection sets made from about 2000 through 2006 have a self diagnostic check feature. It will indicate if there is a error or not and point you in the direction of your trouble.

Based on the error code I or others can tell you more based on the error code and the EXACT model number of the set.

Here is what you do if it turns on for a few seconds and then the power light goes off.

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD ?Menu and Input"(or device) buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC?s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

If someone has one of these codes and needs help let me know.Keep updated here with what code you receive.So i can give you more details.


The above mentioned detail will basically help you know the problem better on your television set.

Green Blinking light of death?

Go through the above mentioned details if you notice Green blinking light of death on your television.
This information applies to Mitsubishi sets that have a Model number beginning with VS, WS, WT etc. It does not apply to the WD series of sets made later.
ONLY 1 of 2 things can cause this problem----

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.

There are sites on the internet selling a "kit" with the caps etc and instructions for replacing them---if they are bad the silver tops of them will be bulged up and not flat.

The above mentioned details will help you know the problem better on your television.So you can take a step forward in taking a decision in getting it repaired by professional or doing in yourself.

MITSUBISHI PROJECTION TV TROUBLESHOOTING?

Types of problems occurs on Mitsubishi projection TV.

If you have a Mitsubishi rear projection where the model number begins with WS or in some cases VS and the set turns on for a moment (green light comes on and goes off) Do the self check most models made from 1999 through about 2005 have:
When the power light comes on and then goes out, on the front of the set press both the MENU and INPUT buttons at the same time and hold them both in for at least 5 seconds and then release both buttons.
The power light will blink a 2 digit error code and repeat it at least 5 times.
This does not apply to sets with a WD model number, they have different codes.
The most common error will be 2 blinks, 2 blinks- a pause and then it will repeat it for a total of at least 5 times.
To get it to repeat this--you have to unplug the set, try to turn it on again and repeat the process.
The error codes are to try to narrow down where the problem is.
If you get one, you can post a question in the Free section here:
Mitsubishi was one of the first to have this feature so techs could with ease know where to look for whatever was wrong--a time saver and several other companies followed suit.

The above mentioned details will help you to understand the problem on your television better.

convergence problem on Televisions?

Go through the details mentioned below, if you face convergence problem on your television.


Many rear projection TV sets made from the mid 1990?s through 2006 develop convergence problems and the reason is simple: Most use 2 IC chips (there are a few that used 3 and a few Mitsubishi use just one) and the chips are on average about 2 1/2 inches wide and 1 1/2 inches tall.

Most have 18 pins or more and are black in color---Most will have a STK NUMBER printed in white on the front of them. The most popular one ever used is STK-392-110, IT was used in Panasonic, Hitachi, JVC, and even some Mitsubishi sets.

The chips have a metal back on them and are attached to a large metal plate usually with fins, it is called a heat sink. A white material like a grease is placed on the metal back of each chip before it is bolted to the metal. The Heat sink compound (or grease) is designed to transfer heat quickly from the part which gets quite hot to the metal heat sink to keep the chip cool.

After some years (usually 5-8) the grease has dried out from the heat it moves and the chip overheats and goes. Depending on what happens it can also take a resistor or two out around the chip when this happens or fuses designed to protect the voltage going to the chip can be blown.

About 70% of the time just the chips need to be located and replaced and the set adjusted with the original remote control.

Some sets are fairly easy to repair with this problem and a few very difficult (RCA?s made from 2003-2206 or Pioneer sets fall into this group).

This can be a do it yourself repair but first you want to determine if it is your problem. All these sets have in the customer menu a way to attempt to manually correct convergence--go there first and see if it will adjust.

If Red or Blue will not move in some direction(left/right or up down) You have a convergence problem.

A lot of sets have an automatic way Hitachi calls it ?magic focus? and it only attempts to adjust at less than 20 points on the screen.

If the set does adjust, whatever the brand, you will need to with the remote get into the tech menu for your set, adjust and SAVE the adjustments.

When it comes to parts you have a lot of options.

1. You can go online and buy a ?kit? for your model----I do not recommend this as it is expensive and usually contains parts you are never going to need.

2. You can ID the chips and buy them locally----I do not suggest this either as it will be as expensive as buying a useless kit.

3. Typical suppliers here sell the chips for about 25 dollars each(X 2) but most of the parts are available online or on EBAY for much less. One good source is Suburban Electronics in Maryland--chips that will cost you 50 for a pair they sell for less than 14 for a pair and they have almost every part needed for this repair.

4. Both chips have to be replaced, I have seen shops that just replace one and it is a ticking bomb. Suburban is also on Ebay-----select advanced search, search by seller and type sewsales55.

The also have a online catalog, this is not a advertisement for them; I have bought a lot of parts for my own use from them----


5.) Remember the old heat sink grease must be removed and new applied when you install the parts.

6.) Taking set to shop may not be a economical option, most get 250-350 for this repair versus under 30 dollars parts cost if you can do it yourself.


The above mentioned details will help you to understand your tv convergence problem.So you can step forward in replacing it yourself or in case getting it repaired by professional tv tech.
