I went to use my analyzer to finish tuning my loop antenna and it would not read swr anywhere.? I did a self test and it showed an error 35 for the first test and an error 103 for the second.? After reading some other messages with similar issue, i took the cover off and found some damaged resistors.? My question is, should I replace just the damaged ones or all of them ( i think there are 6 that looked to be part of the bridge).? Is there a schematic or board layout available?
I suggest you send it back for repair.? You have probably damaged one of the downstream IC's and they can be tricky to repair unless you have the proper desoldering eqpt.
There is no schematic available but there is a block diagram.
The AA55-Zoom is similar to the AA-30 Zero so you can get an idea from the published schematic for this product.?
