I don't think that's true. You can still buy using a credit card.

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.

The TDS5054 scopes were socket 370, not socket 478. The B scopes were socket 478.

Yes. https://www.eevblog.com/forum/repair/tds3014-adventures-(seeking-75-75mhz-oscillator)/msg2766224/#msg2766224

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

No, but I get the digest so perhaps that's why?

Say, didn't you just post about putting context in replies? ;^) Jay

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

Hi George, Check your email. Good luck. Jay

Hi George, While it obviously won't be a perfect solution, I have saved off the cal constants from U1055 and U1056 from serial # B011111. Let me know if you want them, and I'll email them to you. Reco

Hi Siggi, While the models I mention do have aluminum SMT electrolytics on the front panel, I have not seen any that were leaking. I suspect that the leaking caps on the older models were a quality pr

There's quite a bit of confusion around about the capacitor problems on the TDS500, TDS600, and TDS700 series of scopes. The scopes that had all those leaky caps on the acquisition board are: TDS500 (

Thanks Raymond. I finally got a chance to try this. It works, but not on version 3.41 of the firmware. I tested on 3.35 and it cleared the logs, but did not clear the power-up count (which would be ki

Hi Raymond, What command clears the logs? Thanks. Jay

Wrong! Final value fees DO get subtracted?? from the shipping costs that a seller charges. Even if you use Ebay to buy and print the label!

I've found that Goo Gone (and how appropriate that name is!) works great on dissolving that gel. Just scrape off the majority with a soft plastic scraper first. Jay
