Re: HP 34C repair Message #9 Posted by aurelio on 30 Nov 2009, 3:30 p.m., in response to message #8 by Vieira, Luiz C. (Brazil)
Thank you Luiz for your help! I have quite a good new: now the calculator at least wake up!
When I switch on on power up and shows me something in the display:
most of the segments don't light (Don't know if it is a problem of display) but it try tho show: "program error" , the message which usually appears after you replace the battery pacK, I tried to key each number of the keyboad to get something, but what the display shows is irregular and nosense, partial characcers, blanks...I don't know if this dipends on the display, ton he flat cable, on the other components, or on the blue oxidation on the pin of the ICs.
If Iwould like to replace the flex circuit, do you have a picture of the other side? I mean the other end of the flat
THANK YOU Luiz
