Hello community,
after being a passive member of the forum for a while, mostly reading and looking for interesting and helpful stuff...the time has finally come...I need your help
I bought a defective Tektronix TDS210 on eBay. The seller said, the display wouldn't show anything. So i got it for 50€, hoping it would be an easy fix (like pluging back in the powersupply to the main board).
After unboxing and taking the unit apart, I saw that the previous owner has already changed an exploded electrolytic cap. He was even so kind to include the defective one into the package
Unfordunately the power connector was plugged in correctly, so there vanished my easy fix. So I powered the powersupply up, without connectin anything -> the voltages were within specs. After that I connected the other PCBs and testet it:
The backlight of the display works fine, but the display stays black. So I checked the oscillator and bingo, the output is continuously on 3.3V and no signs of life from the oscillator.
The oscillator is a 60.606 MHz type (see photo) but finding a replacement part seems difficult. I found a possible replacement (see attached datasheet) but these guys cost 15€ plus 18€ shipping on DigiKey.
Here comes my question:
Is it possible to replace the defective oscillator with a 60MHz type? At least for further testing.
Has anyone located in Europe one of these 60.606MHz oscillators at hand and could send me one (to Germany)? This may be cheaper than the DigiKey costs
Thanks,
Alex
