Fast reply as usual Geoff, thanks a lot dear.
Untill now, i have checked power circuits and they are ok, and the transmit/recieve circuit look ok, but, the op-amp of the recieve circuit are getting very hot, they are six ICs AD8332, they get really hot even without a probe connected.
I have removed three of them and nothing happened.
Could they broken all together?? the six in one shoot !!
No service manual anywhere, i have searched here and there but nothing.
The problem started oneday about five monthes ago, sometimes they get that white picture, and sometimes works fine, untill it decided not to go back ever
I can hear the relays ticking normally when the device boots, and it senses the probes normally, i mean when you remove the probe, you get "no probe" message, in both inlets.
BTW, this is the device
I don't know where to start !
Greetings
Ahmed
