Question about Mitsubishi WS-65809 65" Rear Projection Television

Mitsubishi ws65809 error code 23

My mitsubishi 65 inch tv shuts off a few seconds after turning it on.
The error code I get is 23 stands for "horizontal deflection failure.
I figure it is a problem in the mainboard section and possibley a resistor and maybe leakage to ground.
Can you tell me where to look or what parts to order.
Do I need to replace the whole board?

Ok there is alot of things that need to be check with this code
check first:
CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB . Before replacing the fly, as I have not had any of these flys go bad, Check all of the capacitors and diodes on the sweep power supply. This is the voltages the flyback makes for the rest of the set. also check pin 10 of IC%A)) for voltage. If there is voltage, the HV protect is on. Check for a shorted or leaky D5A60 in that same circuit. i found this 15 volt zener to be bad a couple of times.
STK393-110. The IC needs to be replaced and also you must check the small fuses in the main power supply that are marked F9A04 and F9A05
also check for
The "oil" is the coolant (ethylene glycol) that has seeped from its containment to the internals of your display. While not a common occurance, it does happen.

Mitsubishi tv ws-65809 shuts down after a few seconds, get a code 23. I was reading a post you said that only needed to soder something?

2,3 is a deflection circuit failure; These sets rarely have soldering problems there or elsewhere.

I would suggest either it is a shorted part in that area (High Voltage and sweep circuits) or it is possible it could be a Glycol issue.

A deflection circuit problem would require a schematic (widely available on internet for free) and a meter to check for voltages and or for shorts.

Glycol can be inspected for visually and if seen care must be taken.

Let me know if you have questions.

Last suggestion would be if you have not done it, unplug set (this clears the error buffer) and plug back and turn set on, if it fails double check the error code again.

65" mitsubishi rear projection tv won't turn

IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

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

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

My 65 inch projection TV turns off within a few seconds when I turn it on. Why? No pictures or sound.

If power light does come on and a few seconds later it goes off---do the self check that the WS65909 MITSUBISHI should have:

On the front of the set press and hold both the MENU and INPUT(OR DEVICE) BOTH FOR 5 SECONDS AND THEN RELEASE BOTH BUTTONS.

Power light should blink a two digit code--error code---for example: 2 blinks, a pause and 2 blinks.

Let me know what code you get----it will repeat it several times---and I will tell you what it means.

Turns of after being watched for several hours.

Do you have the tools required to solder electronics? Do you know how to solder electronics? Have you been trained in CRT safty ? Do you know about High Voltage safty? Is the tv Model number WS-65809? Do you know how to perform static geometry adjustement on a WS65809 if needed? Do you know how to perform static convergence alignment on a WS-65809? Do you know how to perform fine convergence adjustement to a WS-65809?

The answer is :yes yes yes yes yes yes yes yes
You can retreive an error code of 23 or 24 right after the tv shuts
itself off .
There is a 95% chance that I could tell you what to solder , no parts need to be replaced in your television and you would not have to pay someone to repair it.
