Hi, I'm writing from Italy and my english is not so good.
I have a problem with a TEK 2465, last version (without assial fan). I premise that I repaired this scope because a C (180 uF 40V) in the power supply was in short circuit and I also replaced some other electrolitic.
Now when I turn on the scope, A SWP in the trigger section flashing and + e - are illuminated. If I push A/B TRIG switch, the scope start on but I have some problem with the horizontal sweep. I cannot see the B sweep (delayed sweep) and beetween 20 uSec and 0,5 mSec the A sweep is not calibrated (tollerance about 12 %). I see a lot of dot in the readout values and if I try to start the calibration procedure but I must stop because I cannot see the intensified trace for B sweep.
If I do the test, become TEST 04 FAIL 11
Do you know this problem, what can I do ?
Kind regards. Stefano
