I solved this problem once by opening the unit and adding a rubber spacer that exerts pressure on the ribbon cable. I cut the spacer myself from a neoprene-like spongy material. This fix worked for approximately 5 years. The problem is slowly re-emerging and I might have to do it again soon.
Happened to me too. It takes some disassembling!!!! Between the screen and the underlying circuit board is a rubber strip with conductive material throughout which provides ''ground' for the display. This rubber wears out over time, but the quick fix is to turn it a quarter after cleaning and treating the contact surface with 'contact spray'( sparsely!!).
You could have a defective screen or a defective LCD driver, either way you have to replace it. I 've replaced LCD screens before they typically are the entire front half of the radio inside wise. Probably going to cost a few to do it.
TH-79A Kenwood HT and with the power off, hold down the MR button and the PTT switch, and while holding both of these turn on the power. The HT will come up in the remote control mode with the display indication "RC" on one band and the normal display on the other band.
To get the HT out of the "RC" mode just repeat the MR+PTT+Poweron sequence
