Got this Insignia NS-LTDVD19-09 here, it has an issue with the DVD player.
(It's a TV/DVD combo. Appears that there is a similar make with a tan power board, and a different main board. This one I have has a black power board and a big main board)
The PSU had one bad cap by the inverter circuitry, but it wasn't the cause of any issues. The TV behaved just the same after replacing the cap. (It was a teapo 470uF 25V, SC series I think. Replaced with a taicon cap, not the best, but it is the best replacement I have on hand spec-wise (Damn that tiny teapo cap was rated for a large ripple current!))
The issue:
It keeps ejecting the discs back out.
Tried different DVDs, tried cleaning the laser lens.
Checked the spindle motor, it turns the DVD for a moment when it tries to detect the disc.
Next thing I want to try is adjusting the laser power. But the two trimpots seem to be partly burnt out (possibly?), as they don't show any resistance for most of the turn. They show about 10 to 300 ohms for only about 30% of the turn.
From when I opened up the DVD unit, one pot was at full CCW position, and the other was about 40% of the way. (Going from fully CW towards fully CCW postion.)
FYI, I CAN see the laser lighting up, but is it still possible that it isn't powerful enough?
I was told that to use the DVD player you'd have to put the DVD in multiple times until it would accept the DVD. Now it won't accept it no matter how many times you try.
Any advice?
Thanks,
-Ben
