Hi All,
This machine is new to me. Swtd on and could smell what I thought was burning but no smoke before it powered off with the FA error.
Card cage appears to Not have been opened. I guess I could try re-seating the Wave/Power boards?

I have another 852 with not so good tubes I could exchange boards. This machine works fine with a not so great picture.

Gentlemen all, I defer to your greater wisdom Confused

The NEC error codes are here:

Bad astig board is what the error indicates. I have spares.

Thanks Curt.
Can a board from xg110 be used? How do I locate and identify this board?

Found the astig board,thanks again Curt. Can one be used from a 110?

I'm not sure, they might be different...

Sorry, that wasn't helpful.. Smile

The board numbers (PWC XXXX) will most likely be the same, but there might be a stamp on the boards, 2R4 or 3A5. Those HAVE to match, otherwise the board won't work. I can repair the board if you want.

Curt, as usual the info is invaluable. The board in the 110 is 2R4-1 same as the 852. I will try to swap boards today and see what happens.

Thanks,
Phili

Hi Curt,
I replaced the A-drive board from the 110 to the 852 and now it stays on! But, had to take off the Blue neck board for this operation and now no life from the Blue tube. Before exchange of these boards when I powered up, all three tubes were lit briefly till it powered off with the FA error. I was being careful Confused

Check to make sure you didn't bend a pin on the blue tube. Check all connections. THe A board has nothing to do with the blue tube being on or not, so it's not the A board.

I guess that 110 is an 1101 LC. The last digit is important...we aren't psychic!

If not, then the A drive should not work, as the powersupply rails are different voltages....THE SMOKE MAY COME OUT!!

I don't know about the blue neckboard. Need more info.

If the 110 is an 1101LC fit the neckboard from that.

Hell...if the 110 is an 1101LC why are you playing around with a 852 AC???

Hi Mark,
The 1101 is Not LC.

Are you saying the A drive from the 1101 should not work in the 852?

I checked my re-connections on the Blue neck board to find I could see pins, so I pushed in all the way but still did not come on.

Also, on the 1101(with toasted tubes,now using for spare parts) there is a wire coming off the clamp that holds the neck board to the cover for neck boards. is this a ground wire?

Will the neck boards from the 1101 work with the 852?

Thanks,
Phil

If it is not LC, is is NOT an 1101.

It is an 1100. Read the label on the back.

No parts (except deflection board) are interchangeable. The powersupply outputs different voltages.

So NO the neckboard will not work.

No the A drive should not work (due to the powersupply voltages), and I'll be surprised if the inkstamp number is the same. Check the boards very carefully - make sure they are identical 100%!
(Curt do you know what's going on here? Is it only the F and C drive that use the particular voltage rail that changed?)

The 1100 is almost useless as a parts pig for an 852. Sorry. You really need an xxx1 XG or ideally an xxx2 XG to swap with.

All XG A drives are 2R4 and have the same part number regardless of version. Marks correct as well as Curt for making sure the prefix ink stamp matches before swapping boards. The A drive part isn't a concern. Doug

Thanks Doug

I was wrong about the A-drive. It's different to the C and F drives, which will not swap (you can go backwards if you change a jumper).

Looks like it's your lucky day Phil....well, maybe not the neckboard, that won't swap.

Thank you Mark and Doug for the continuing vital information.

philm,
If the blue still wont come on I would suspect a pin is bent on the tube, a connection is left off the neck board or possibly the V drive but I would first have to look at what was done last in that order. Your overlooking something.

It does sound like the A drive was bad but now the blue not coming on may be unrelated to the FA error. Might make sure AKB is turned on but look real close at the connections and pins. Doug
