Tektronix 210 blank screen

Thank you for your reply. You got better quotes from them then I did on the main board. I think I have the problem traced to a(I think it's an A-D)chip on the mainboard. I have no schematic and they seem to use Techtronix part numbers etched on their chips whichs makes it hard for me to cross reference. It sucks because I can't afford the 600.00 (what they quoted me) for the main board.

Thanks again. Shane

If you have the *Tektronix* part number,order that number from TEK. If it's not orderable,they will tell you. (perhaps you could ask who the manufacturer is,and their part number.[cross-ref])

TEK part number format; xxx-xxxx-xx. Commercial-purchased ICs are 156-xxxx-xx. Custom TEK-programmed ICs are 160-xxxx-xx or 165-xxxx-xx.

TEK no longer has any IC manufacturing itself;No more TEK-made ICs.

Hi there,

well AFAIR Tektronix does only do repair on the basis of "module swapping". Which might be okay for a TDS210: here are not many parts to replace, most stuff is surface mount and the main A/D is part of a near postcardsize board.

So, if you look into ebay you are often lucky to get a comlete and working TDS210 for less than 600 USD/ 400 Euros. YMMV

hth, Andreas

Yes, but there are still TEK custom designed chips in the instruments.

Then the Q is "do they have real TEK part numbers etched on them?"

If so,they may be orderable from TEK.

They will be identifiable. I don't know what numbering scheme is used, as I don't have any newer instruments.

I checked with tek support and they will only sell the main board. I was wrong when I said the tek # was etched on the chip, it is silk screened on there along with the National Semi part number ADG322B and the other ADG321C which I have not been able to cross reference. Parts Miner and the Likes have a min. order of at least 250.00, but I don't believe they have the parts anyway. Anyone know of any other places that might have hard to find chips?

Thanks Shane

Just for grins,what was the TEK p/n silkscreened on the IC?
