NEC DM-2710 Professional Video Monitor Repair

Yeah c5015 is connected across a winding of T5004 and unless the transformer is removed from circuit it's winding resistance will probably dominate any resistance measurements made across the solder pads of c5015...

Right. I pulled the Transformer off the board and measured the resistance/continuity between the 2 sets of 2 pins on the left side of the transformer and they are shorted. I guess my question is should they be this way? What I am really trying to do here is find out what is causing the noise in that area of the board and why its overheating the resistor in the same area. could the noise also be coming from the resistor? What would be the first logical thing to check as to what the cause of that is?

The transformer will be wound with heavy wire & not much so you
will get very low ohms.
Unfortunately the ZOOM doesnt blow things up enuf so I can see it.
The hoz lin & pincushion usually will be in series with the yoke. Follow the hoz
windings of the yoke from the collector of the hoz out transistor through. Watch for a yoke coupling cap in series with it. Also look for any diodes off the C of the hoz output. If any lift one end & do diode test with your meter.

Yes I did do some monitors inc NEC. I am NO expert in them. In fact I hated
monitors. I was doing piece work for a cat & told him " no more monitors ,
projos, or VCR / TV combos". All a PIA.
Keep in mind monitors were fixed BOARD LEVEL ONLY as far as a MFG goes.
Even getting a manual set you back $50 - $75. Add to that you could not
buy parts ONLY boards. If you get this going you will have something to
be very proud of.........
