You posted your concern as generic with no specific brand or model. Flashing displays can mean a variety of things to different makes. Some of which are:
1. Low battery. Low memory battery;
2. Error in programming;
3. Error in firmware;
4. Fatal error in self-test/diagnosis;
5. Major component defect detected; and/or
6. Out of range/band.

In the same token, corrective measures can likewise be anything:
a. Recharge/replace battery;
b. Reprogram/reload program;
c. Update firmware/clone;
d. Run diagnostics using an external device (often a PC);
e. Determine which is at fault (finals, VCO, PLL, voltage regulator, replace);
f. Tune back to standard freq.

Most often (but not always), it can be also be corrected by doing a reset of the radio which can be:
i. Pressing FUNC (or some other button) while powering up;
ii. Pressing a recessed/hidden reset button;
iii. Placing a temporary jumper/shorting two (2) points (internally on the logic board);
iv. Remove battery/power (including internal if any);
v. Pressing a sequence of buttons to enter MENU/SETUP mode.

Hope that this be of some help/idea. Pls post back how things turned up or should you need additional information. Would appreciate also if you can specify brand/model/region.

Good luck and kind regards.

How can I program the Kenwood TM-G707 A/E transceiver to our new repeater with a REC. of 151.1225 TX of 159.015 with DPL of 172 and 134?

I believe that your transceiver requires a simple mod which involves removing a surface mount diode or resistor usually found in the front display head.This allows the device to operate out of the intended frequency band.You may Google Transceiver TM-G707 A/E Modific ations for further info.

TXSR875 reciever display

Hi and welcome to FixYa,

Two possibilities:
  • the Pure Audio feature has been engaged. This turns off the receiver's front panel display;
  • heat related issue. A common fault that develops is component failure, specifically, R9304, a 10 ohms dropping resistor connected inline with the +44V display supply.
Should you be considering a DIY (do-it-yourself) repair, please postback for procedures. Otherwise you may have to seek the services of an authorized service center (specially if under warranty) or a qualified professional

Hope that this be of initial help/idea. Good luck and thank you for using FixYa.

Receiver lcd display doesnot work

Does the 605 have the "pure audio" setting (my 705 does)? If that is selected, it cuts out the lcd display on the front.
