Re: Help with Next Megapixel 17" color (aka Sony m41kka16x)
It's closed back up and in the "I'll get to it someday" pile, so I don't know if there are any other markings.
I couldn't find a free service manual to DL for the CPD-17SF1.

Re: Help with Next Megapixel 17" color (aka Sony m41kka16x)
Never found any service manual. I dug into it since I didn't have anything to lose. I got it to power up (and stay on) by replacing every capacitor and a voltage regulator IC on the PSU board that had the leads corroded by electrolyte.
Then I replaced every cap on the analog board because I could smell electrolyte when it got warm and lots of the caps looked suspect. I still don't have an image, though I have raster now. Some small pots on the analog board look like electrolyte got to them, but I haven't...

Re: Repairing a Next 17" Megapixel Display
Compare it to the good one from the Blue input section in another photo. See how the green plastic bit is flared out? The part looks damaged to me. Maybe some electrolyte got inside & corroded it - it really looks like the stuff around it is corrosion of some type, not glue. The other two don't have any signs of that stuff.
OK - thanks for the input R_J.
Many of the caps DID vent from the bottom. I don't have good pictures, but most of the larger ones are a mess underneath.
I'll start by replacing...Last edited by bclkjs; 12-04-2017, 06:44 PM.

Repairing a Next 17" Megapixel Display
Hi,
I'm slowly trying to bring a dead megapixel (aka Sony Trinitron M41KKA16X, possibly aka HP A4032A) back from the dead.
First step was to recap the PSU and replace a power regulator IC, this got it to stay powered on instead of shutting off immediately. Next, I could see a glow in the tube but couldn't see raster, until I turned up the screen control on the flyback a little... PROGRESS!
When I connect the next station and turn it on, the display flickers at the top & bottom but there's no visible image. On the input board, it looks like the cap...

Identify this capacitor value
Can anyone confirm whether this is a 3.3uf or 3uf capacitor?
I've never seen a marking like this and the spacing of the 3's makes me wonder.

Help with Next Megapixel 17" color (aka Sony m41kka16x)
Hi folks,
Hoping someone here can point me in the right direction.
I have a Next display that has the following symptoms: Turn power on, display powers up, a few seconds later there's a click/hum (kind of like a degauss) and the power light goes out. If I turn it off and back on again, nothing happens. If I turn it off and wait a bit, it works again for a few seconds.
I can't find any schematics for this or for the Sony. Next sold a couple of these displays that were rebranded Sony's, Hitachi's or Fimi-Phillips.
I've found posts on...

Re: New Members - please post your introductions here
Howdy from Denton, TX. I have a Next Megapixel 17" (aka Sony M41KKA16X) and I can't find schematics on it. I'd love to make a post in the displays forum since there seem to be a lot of knowledgeable folks in there. I've performed board level repair of many vintage PCs and it would be great to fix this old display. Thanks!
