TERRA Operative:
A bit of fun today on the bench.
First I reassembled the first one of roughly three IBM Thinkpad T42 laptops from the box of parts I have. I have one good one that I use for the times I need an old laptop with a real parallel port or dual PCMCIA slots etc which works great, so time to build up a couple working laptops to sell off.
Then it was time to fix a Philips PM 5518-TX VPS colour TV pattern generator. I have two and this one with the RGB output option wasn't working but it just turned out to be the main logic board that needed to be reseated, so it got a bit of Deoxit on the card edge connector for good measure. The second one (without RGB output) will get sold off.
And finally, I dug out this Trio (Kenwood) CS-1577 30MHz analogue dual-trace scope.
I bought it years ago, like maybe 6 years for peanuts, I think maybe 1000yen, or less than US$10... and it had some new capacitors installed and a bunch of stuff deoxited by me at the time, but I never got around to reassembling it properly.
I somewhat reassembled it a few months back and found no trace, so now I want to get rid of it I thought I'd get it working..
So far I have found it works fine in X-Y mode with a beautiful trace, so HV works, the input board works, and the PSU is ok.
But when I try to use it in Y-V mode, no trace...
After poking around at the panel controls I found if I hit the trigger reset button a trace briefly flashes on the screen, showing the expected waveform but only for a brief moment.
Ok, so the horizontal is working, but the trigger is somehow busted. Luckily I have the schematics, so time to go huntin'.......... :-/O :-BROKE

Holy shit, I'm not surprised at it not working. It's like I said in another post, some people lack brains and what makes it even worse is that more than likely some stupid dipshit will more than likely buy this as well :palm:

Hey, at least you can see everything that's been robbed off it before you waste your time & money... and if I were in dire need of something it actually has, I might pay more than I want to for it to save myself myself the guilt of robbing it off a decent example. :-//
Just sayin'...
mnem
might, I say... might. If I were really desperate for that part.

Well that's nice, but it has 2 things wrong with it, 1/ it has a really crappy LCD screen which seriously detracts from its usability, poor resolution and contrast, 2/ It doesn't have an = key :-DD
The second, is not really a problem, just an inconvenience and requires a small rewire of one's brain in order to work it correctly, the first is in my view a major design flaw especially when the cost is taken into account, a few cents more on the BOM and it could have been a winner. :popcorn:

Ah, but there you'd be wrong! This is an example of a later 48GX that has the high contrast screen (standard on the 49 and 50g). Very hard to find. :P
