    tv comes on for a second then shuts off. Light flashes 3 times

    My Mitsubishi VS-50705 wont turn on. When you push the power button you hear a click and the power light comes on for a fraction of a second but it doesn't turn on. I did the diagnostic and it flashes 2 then 4. What does losing vertical from source mean? Should I bother getting it fixed or is my TV done for?
    Thanks

    I have same problem with VS-50705, when press input andmenu at same time, tv blinks two times twice. It talks about short protect.

    I have the same problem. Push power button and it comes on for less than a second and then turns off again. If I unplug the set overnight and then plug it in right before I turn it on it works fine.

    TV shuts itself off and will not completely turn on again. The power light flashes on briefly and then off. When I unplug the TV and plug it back in green on light flashes 3 times.

Good Day, PCMcGee; To start try these: 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. Good Luck, big IRISH.

Vertical bars and lines run up and down the screen. Need service manual or parts outlet


There is no such thing as a "vertical sweep circuit board" in that set. The vertical circuit is part of the sweep module. And BTW that type of symptom is more often a power supply filtering problem anyway.

Power off is when you press the switch.
Shut down is when you turn off from remote and TV stays in standby with led on.

There should only be a couple of STKs, the R's are resistors, they STKs should cost under $20. This should be everything you are looking for. If you need anything else, let me know.

you would need the service manual to even begin to repair it yourself as it could be literally 50 different reasons why it isnt powering up. I would suggest getting a service manual at the following link , as they will email the manual to you after purchase and then they will provide free tech support to help you diagnose the actual problem , but its a hopeless cause without the service manual. Heres the link.
