Question about Mitsubishi VS-50607 50" Rear Projection Television

1 Answer

Diagnosis 23 My TV now turns on and then off right away. I get a 2-3 when diagnosing the problem. This is what I would like to ask: How much can fixing 2-3 cost me and who could do it? I am not a tekkie.

Protection cutting in can be caused by many different things, at least half a dozen.

Most of the time on a Mit, this is caused by the conv sys blowing a fuse that operates it, which is the same power supply that keeps the unit on. When that fuse blows, the voltage from the power supply that keeps the set on disappears.

The 5A fuses that keep the plus and minus 24v rails going are little green things that look like resistors, but are actually "IC protectors". They can be replaced by regular 5A fast blow fuses, GMA type (also known as F type - small, and hopefully pigtail, for soldering to the bad fuses. Parallell one or both of them onto the blown little green things after testing each with a VOM, which can be done easily in circuit while the unit is unplugged.

If either of those 5A fuses are blown, chances are you'll need to replace their conv ICs as well.

Mit's will work with their conv ICs disco'd - you'll have no conv correction, but the set will work and you'll see an uncorrected picture. At that point it's a shoe-in that the conv ICs are bad and need to be replaced.

TELEVISION WILL NOT TURN ON. WHEN I TURN IT ON EITH MANUALLY OR USING THE REMOTE, I CAN SEE THE LIGHT GO ON, THEN THERE IS A CLICKING SOUND IN THE TELEVISION AND THEN IT TURN OFF,, THIS CYCLE TAKES...


Howdy,
First reset the TV by unplugging from a/c source for about 3-5 minutes. Plug TV back into a/c source. Then TV back on if no fix try this to isolate problem:

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/device 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. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES.

2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB.

I hope this helpful, Good Luck, Big Irish.

Will Not Turn On


First you need to do a self test diagnosis and then if it comes up with:
SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB
Do self test by pressing Input/Device and Menu at the same time for 5 sec. the set will show a 2 digit seq. first blinks followed by a short pause then the second.

Good Day,
Why not try to fix it, it's hard to find a board and easier to repair. Try these; 1). CHECK IC700 PIN 20 (AC-OFF) FOR 0 VOLTS DC. IF HIGH, CHECK FOR LEAKY D980 PART # 264P045040 ON THE MAIN PCB. 2).
