    Same problem, blue lights flash five times. No picture, no sound. The manual says Lamp, but I've replaced it and it still does the same thing.



    Many posts say it's the Light Engine.

All I get is a blue welcome screen on my Mitsu WD-65C9 DLP TV. After several seconds of blue screen, it always just shuts down. I downloaded the Mitsubishi software upgrade, but it did NOT solve...


Hi Mike,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.


Kind Regards,

Mjsazon

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

No picture or sound. standby light on front panel


The light is blinking a repeating error code. Try to determine the number of blinks before a slight pause as that will be an error code. Then respond to this same post and I will assist you with diagnosing what may be causing the set not to power up.

Hi,
5 times blinks shows incorrect white balance (AKB) error. TV needs Screen Volts (G2) adjustment.
Take off lower front panel, find Focus Block that has 6 control knobs, adjust Screen volts of each CRT (red-green-blue) and problem will be solved.
Be Careful while working in TV.
Let me know if you have further question.
Thanks.

Yes I should be able to help you figure it out. First look on the rear of the set to check what the chassis number is. Should be an ATC 336 but it might be a ATC323 let me know the chassis number and we can go from there on diagnosing the problem

WS-55515 Loss of sound and HD blue screen


First check set for problems by: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. Self-diagnosis error 2-3 indicating deflection failure. Check for shorted or leaky Q5A37 part # 260P818050 located on PCB-Main. If found defective replace only the transistor instead of the Main PCB.

I have the exact same problem with my tv. Unfortunately, I'm not sure what is wrong or how to fix it either. I notice your post is from July. Have you found a solution since then? - Sarah
