Re: Yamaha TSX-130 dim display

UVZ1J220MDD is the same as the UVZ1J220MDD1TD; the 1TD refers to the packaging as Tape Dispensing or some such.

The display on one of my two TSX-130's died after five years of being plugged in, i.e., the display had been on continuously for five years (i.e., the unit was not unused in storage. My second TSX-130 had been mostly unplugged for over five years and its display is fine.). Prior to dying totally the display had become dimmer. The fix was to replace C63 and C64 on the power supply board. The factory Jamicon SK capacitors were replaced with Nichicon VZ series (part# UVZ1J220MDD1TD). The Nichicon VZ series has a higher temperature rating than the Jamicon SK series and should, hopefully, last longer....

Re: APC Back-ups RS 1500 Dead



No ideas. I was unable to locate a service manual or even a schematic. And because none of the caps were bulged/discolored the solution was not clear in the case of my board.

I replaced the unit with an APC SMC1500. BTW, I wasted time exploring APC's swap program (I've forgotten APC's name for that program) but it was less expensive (and less hassle) to buy a new unit from a retailer rather than dealing directly with APC. (USA. I don't know if that holds true for other countries.)...

My board is labeled 640-0253E in the bottom right corner (when the big transformer is in the upper right).

My RS 1500 (tall, narrow, beige) is not dead but has started constantly cycling between on-battery and on-AC. None of my other UPS's are unhappy with the incoming AC, which seems to be steady at 122V. There are no expanded caps or burn spots on...
