I picked up a Benq FP71G and the previous owner said the monitor would stay on for 15 to 20 minutes and then shut down.
I took it apart and noticed no obvious bulging caps, but when I looked at the other side, I noticed 3 possible issues and would like comments on what I found.
1) C826 solder joint is fused/touching the middle lead/pin of Q809. I don't think it should be touching. The other C826 joint is NOT fused with Q808 (mirror side). Should I unfuse this so they are not touching?
2) T601 lead/pin 7 has no solder whatsoever. It is perfectly clean like it was either purposely not soldered at manufacturing or totally missed by mistake? Should T601 pin 7 be soldered?
3) There is discoloration in the solder on some of the pins/leads on most of the transformers. See T801 for an example. Is this bad solder and should I retouch? The spacing is very tight and I don't want to unless I absolutely have to.
I'm surprised the monitor even works (I powered it up and got a picture, but shut it down to avoid further damage).
