Cambridge Audio 840A Amplifier - Faulty?by individual689114,376 views
Thanks for the tips! I was able to repair a DSP-A1 that I've had in the family since it was new. With just a little clean-up it literally looks and performs like a new unit. These were Yamaha's original monster home theater receivers and they still outperform the newer units albeit without all the new bells and whistles.

Thank you, thank you!
I had this problem for several years now and saw your video but was afraid to begin with it. I'm not an electronic expert but after failing of the whole display (tapping on the display wouldn't help either) i had to do it.
Following exacly your instructions i had it repaired in two hours!
Great video!

I just give mine a tap on the display and it kicks on. Yeah, temporary solution, but if I try to fix myself, I know I'll screw something up. As long as it plays, that's all I need.

JasonF99, I followed your instructions on avforum to fix the audio problem by desoldered the potentiometer from the volume control board. Then, I dismantled and cleaned all contacts and tracks. I also bend the metal contact a bit to increase the tension. After completion, I put everything back together, but it didn't fix the audio problem. Do you have other ideas?

Great video. My amp has had this problem for over 4 years. I saw this video last week, fixed it the next day.

LOL the light was on, but it was a home cinema environment so still a fairly dark place to work. We didnt want to go to the trouble of moving the whole amp and disconnecting all the cables so we pulled the display and moved that instead.

Belated reply, but any of the pins from the VFD (vacuum flourescent display) can have this problem and as its fairly involved to take it out, its simpler to do them all at the same time. You cant always see the expansion cracks when the display is cold so if you miss one you have to dismantle the amp all over again.

Hi, im the fixer in the video here, try Yingwang166s solution first but if that doesnt solve it the problem might lie in the volume control itself. Mine ended up having this problem. Its a very involved fix but it is fixable.
