TV Repair Questions? Ask a TV Technician
Model # XXXXX I think it's from 2004-2005
yep. I even jumped it to see if the switch was the issue.
I'm in the process of moving and my voltage meter is at the new house. I may be going there this afternoon and can check it tonight. I may need more guidance on what the DMD board is and which wires to check on both the DMD and the ballast.
I have the meter. What would you like me to check and what voltage am I looking for?
I have the meter now.
Ok checked the voltage coming inot the set, 110, out of the card to the first set of jumpers, 110. I'm going to look at the brown and blue wires going to the ballast next. Are those AC or DC?
It gave me access denied when trying to upload. I will try again.

Do I unplug the connector and test the harness end or the board side? The pins are VERY small, do I just stick a single wire into it and test that? Lastly about how many volts DC am I looking for?
Starting with the Blue wire in the harness:
Blue = 7 Volts comes on when bulb / fan comes on goes on and off with bulb and fan
White 1 = 3.4-4 volts only on with when the light is on
White 2 = 12 volts comes on and stays on pretty much the whole time, did drop onece or twice but only when the tv cycled.
White 3 = nothing
White 4 = 7 volts comes on and off with lamp start up.
Its just a basic analog meter set to 10 volts.
But the bulb turns on. I can see it on and I can see tye color wheel spin.
Here is a video of what its doing.
I am going to order a new ballast and see if that fixes the problem.
