Sears SR3000 RGB Monitor (Circa 1986)

Throw it in the back of your Model-A and take it to a dump.

Or monitor recycling center.

Thanks for the helpful advice!

Sorry, just kidding. Actually I have very fond memories of my =C64.. I learned 65xx assembly language on it (anyone remember HESMON?)

Anyway, if you've never tried one of the Commodore emulators (e.g. MAME32) they are a kick and a half.

np ;)

I'm just trying to squeeze a little more life out of this monitor. It always had a MUCH better picture for video game systems than any TV I'd seen.

Does Mame emulate a C64?

How many things did you unplug while in there? Just remove the cover again and re-check all the connections that may have become unconnected. That's about it. I doubt you killed it.

p.s. You have some voltage (you are getting sound) but no high voltage at the tube. Check the connector at the back of the tube, and any wires going from the tube to the circuit board.

Obligitory: Don't shock yourself, you can die trying to fix a $1 monior :-)

No, but MESS does.

It's an RGB Monitor. Reopen it, deconnect everything, make sure that you haven't damaged the board (carefully inspect it) nor any component(S) on it. Reconnect all the connectors in the right place, ON !

you'll have to give us more than that. check: filaments lit? HV present? raster? (turn up G2) checked for cracked soldering on mainboard, esp. near input sockets and filament connector?

Ben,

There is a faint glow (orange-yellow) in the tube on the back of the display when powered on.

The video-in jack(?) is a little loose, but so is the audio jack and it works fine. I don't see any connectors that are loose.

I'll read the FAQ and go from there. Thanks.

Try adjusting the control on the flyback transformer marked "screen" or "G2". When you turn this clockwise, you should see something on the screen. If you only see a think horizontal line, look for a switch on the CRT board, or main board that's labeled "service" and try switching it. If you then get a picture change it back to the service mode and adjust the screen control until you get a very dim white line. Andy Cuffe

I almost thought that Mame could, except maybe for the SID. I think some (many?) arcade games used the 65xx processor. I've used CCS64 as a 64 emulator.

I haven't looked at MESS for quite a long time. I can't believe how many systems it emulates, or that are in progress! I'll have to check it out.

When looking for the flyback transformer (didn't know what it was) I noticed a connector that was loose. Now I get a lit screen (bluish-white), with white lines. (!)

The service switch you mentioned before (labeled SER NOR) is on "normal". When I switch it to "SER" the aforementioned white line can be seen.

I've turned both knobs on the side of the flyback transformer labeled "screen" and "focus" with neither changing the picture.

At least I know the screen is getting power and isn't dead. Any ideas?

Sounds like the focus and screen wires from the flyback aren't connected for some reason, look for more connectors that may have come loose.

Screen and focus will change the output, I mispoke.

What I meant to say was that nothing that I can change (knobs, switches, etc) can bring my video input to the screen.

Sorry.
