Yaesu FRG-7700 display ???
The freqency /time display doesn't blank any of the center segments on
either time or frequency function. Any suggestions on a fix appreciated. The serial number is 59,800 and I wonder if anyone can tell me if this is an early or late model? tnx -- 73 Hank WD5JFR |

All the center segments stay bright, no blinking.

It's a five digit display made of seven segment digits. The center or "G"
segment doesn't blank when zero is displayed so zero looks like an eight. It has leading zero suppression and instead of the zero being totally suppressed the center segment appears as a minus sign. -- 73 Hank WD5JFR "dxAce" wrote in message ...

I think his problem is a 0 looks the same as an 8 and a 7 looks like a backwards F - the middle horizontal bar is lit all the time. tnx -- 73 Hank WD5JFR "dxAce" wrote in message ...

I'm certain someone will be able to help you out. -- 73 Hank WD5JFR "dxAce" wrote in message ... Henry Kolesnik wrote: All the center segments stay bright, no blinking.

Did it get dropped? Or maybe a soda spill? B.H. |
"Henry Kolesnik" wrote in message m... All the center segments stay bright, no blinking. tnx If I understand you right, it sounds like you have a shorted transistor driving either the rows or columns of the multiplexed display. |
Check the segment transistors position Q1052-Q1056 (2sa733a-q)
One of them will probably be shorted. The signals for the transistors are coming from ic msm5524 controlling the frequency and time display. Greetings Peter "Henry Kolesnik" schreef in bericht m...
