Miller 2050 plasma press alert

When I turn on machine I get power and ready lite. Then 2 1/2 seconds later ready lite goes out and press alert comes on. I have correct press thru regulator to solenoid and the press switch ohms out as closed above 40 psi. Since I have two 2050s, I swapped the 4 PC boards(2 on each side) as well as the torch/hose assembly and still have same symptoms. Any suggestions as what to try next? Tom

Mitshubishi plasma tv ws65869 wont start green led on in a sec off


Not a Plasma by the model number listed.

When green power light comes on and goes off a few seconds later:

Press and hold on the front of the set both the Menu and Input (source) buttons at same time for at least five seconds and let both go.

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

If set has been unplugged it clears the errors and you must turn on and when power light goes out repeat.

Let me know error code found and I will help

Power light blinking fast and voltage is fluctuating on load side of system and no power to handle


The machines that I have seen do that need the main circuit control card assembly. It is not a cheap circuit board either.

Green lite comes on for about 2 to 3 seconds then shuts down red lite pulses


If the back was off the board on the left is your Ysus board. It will have a cable plugged into the right side of the board from the signal board. Unplug the the Ysus board. If it stays on without a picture change both Y and Z sustain boards. If this helps let me know.
