TDS784D with faint display and blurry image
Good to hear from you as well! Still around and read Tekscopes regularly, but much of it doesn't interest me as it's mostly vintage stuff. Also still buying, repairing, and re-selling scopes. Looking

Hi Tam, To be fair, I only gave you that price as I was repairing your acquisition board for memory failures. There's no way I could do the repair for that price if that were all I was doing... Thanks

Weird. Yeah, if I go online I have to click on "view quoted text" to see what you wrote... For some reason, your emails to the list appear as quoted text.

Nothing. Is it just me, or everytime that "Ray astrodroid@..." posts something there's zero content?

eBay / PayPal Changes and our alternatives
I don't think that's true. You can still buy using a credit card.

TDS794D, alleged shorted power supply?
A likely candidate if the scope is cycling on and off is the CRT assy. Easy to test for - just disconnect the ribbon cable to it.

TEK 5054 CPU Fan
The TDS5054 scopes were socket 370, not socket 478. The B scopes were socket 478.

Hi Steve, Make sure that it passes SPC from the utility menu - at least 10 times with no failures. Also run the full self test from the same utility menu. Jay

TDS694C 50 Ohm Overload
Hi George, I believe that is the input preamp, not the ADC. There's a good possibility that someone overloaded and killed it. They are BGA devices so they're not very repairable without a donor board

Hi George, This is the problem you will need to repair before you can move on. Do all four channels seem to be more or less working (displaying a reasonable signal)? Using a DMM, do all four channels

The DS1486 contains the options, TOD, and the SPC constants. I would think that B012XXX firmware would be the same as in B011XXX or at least close enough where it should have worked/been compatible...

Hi George, If all the cal parameters other than SPC show as "initialized" then there's two possibilities: 1. The U1055/U1056 binaries you used (if you got them from me) are not compatible with your sc
