ICOM IC-R9000 DATA "0008ch ERROR or 0517ch Error ...ERROR ch Was CLEAR"
Hello to all
I checked and renewed some solders in CRT's PCB, cause I had the horizontal axis that sometimes turn off...there were of the welding cold, I also replace the memory battery and placing one socket with two wires in a way that can be stay near the clock battery to be more accesible....BUT...after had reassembling all The receiver does'n function.... The Logic Check says all Passed for all steps execpt the DATA steps return "0008ch ERROR or 0517ch Error ...ERROR ch Was CLEAR" I try to remove the memory battery and nothing change The radio does a logic check on its own when turned on, and everything passes except "DATA." It shows, "ERROR 0008 ch ERROR." Beneath that it says, "ERROR CH was CLEAR." If I command a logic check by holding down the "SPEECH" button while turning the power on, the DATA line shows "Passed," and it goes to 2.000 mHz, which it both displays and actually receives. As soon as I turn the tuning knob, the display blanks and the receiver mutes. Pressing any of the mode switches from the muted condition brings up a display of 10.000 mHz, and it actually does receive at that frequency also. Again, turning the tuning knob kills the frequency display and mutes the receiver. If I don't touch the tuning dial while it is on 2 or 10 mHz , I can use the up - down knob to select 2 mHz on ch 000, 5 mHz on ch 001, 10 mHz on ch 002, 145 mHz on ch 003, 430 mHz on ch 004, 2 mHz on ch 0P1, and 26 mHz on ch 0P2. I presume those are some test frequencies that reside in ROM. Turning the tuning knob at any of these frequencies blanks the display and mutes the receiver. When one of the before mentioned frequencies is displayed, pressing either the "MHZ UP" or "MHZ DOWN" buttons locks in that frequency until the power is turned off. The CPU seems to be OK. Various other functions it controls work correctly. I have tried the logic reset procedure of holding down the "clear" button while turning on the power, but that didn't help. Any Help ? Thanks a lot Andrea |
