    My tv is doing exactly the same. I'm calling around for repair quotes and the lowest I have so far is $200-$300 with a $50 service charge to come to my home. Is this a difficult thing to fix as a do-it-yourself project? If I had step by step instructions, I would think I could do it but how would I go about finding instructions?

1.) 2-2 is short protection and usually means one of the two fuses that protect the convergence IC are bad.

2.) This model uses a Single convergence IC--A STK-393-110 THAT can be purchased for about 14 dollars plus shipping on ebay.

3.) If one of the fuses that protect it is blown the set detects no voltage present and shuts down instantly.

4.) I have photos of what the fuses that need to be checked look like; also there are several protect resistors around the chip that need to be looked at also--I have photos of them also.

5.) I also have step by step start to finish instructions for this repair for this model--It tells you how to do the repair and everything you will need to do it.

6.) If you want the photos and instructions give me a vote here and I will email them to you free.

on the signal board replace the caps by the 5/9 volt regulators. c2p04 is the main culprit. 6 caps in total can be changed. I believe c2p05 also.

Good Day;

More than likely your TV has "COOLANT" (ethylene glycol) on the circuit boards. This fluid comes from the CRT's (picture tube) this fluid is used to keep the CRT's cool, such the name. This fluid from the CRT's leak when TV is on for long periods of time, the chamber expands and the seals leak.

One can remove this fluid by using "acetone" & small brush. The fluid is hard to see, use bright light, they spots can be smaller then a DIME. Also, the fluid can corrode the parts and traces on the boards. To protect the TV in future place heavy plastic or thick cardboard over affective area, make sure TV has proper air flow around TV.

If after the fluid has been removed and TV still does not work, call an Authorized Service Center to come out and repair TV after giving you an Written Estimate. The boards are not available.

Always try resetting the TV by unplugging it for one minute then plug back into A/C outlet and ALWAYS UNPLUG TV BEFORE ATTEMPTING ANY REPAIR ON THE TV.

Good Luck, big IRISH.

SOURCE: Mitsubishi WS-65313 - Will not turn on

The most common failure are the two convergence integrated circuits part # 267P173010. The two pico fuses may be open as well, which come from the power supply and provide +24 volts and -24 volts.

I have a mitsubishi ws-65315. When I go to turn the tv on the green power light comes on and you can hear the tv click on, but seconds later shuts off.


this model has a self check, when green light comes on and then goes off. Push and hold both the Menu and Input buttons on the front of the set for at least 5 seconds and release both.

Power light will blink a two digit error code like 2 blinks 2 blinks, a pause and then repeat it several times.

Let me know what error code you find and I will tell you what it means.

Hi my tv is the ws-55315 and i turn the tv on the light comes on for a second(the power light) and the tv shuts off is that the bulb i dont know?and how do i fix it


WHEN the power light goes off on front of set, press and hold both the menu and input (device) buttons at the same time for at least 5 seconds and then release both buttons.

Power light will blink an error code: most common is 2 blinks, 2 blinks, a pause and it will repeat code several times.

This is self check and will narrow down what is wrong with your set.

Let me know what code you find and I will tell you what it means.

TV turns on, then turns itself off about 2 seconds later.


set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

Good Day afsho;

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. Shutdown at power with self diagnosis error 2-2. Check for open fuses F9A04 and F9A05 part # 283P144080 on the +24 and -24 volt lines. If the fuses are open the convergence output circuit would be suspect. 2. Shutdown at power with self diagnosis error 2-1. At power on check for 12-volts DC at connector KH pin 8, if missing check IC9C51 part # 270P990010 and L9C.

good luck, big irish.
