In case it's useful to anyone out there, here is how this radio comes apart. Do this at own risk!!! First, the bottom cover is taken off by removing the one screw in the middle, and then prying the rear end away from the chassis (both of mine are pretty tight, but don't worry, there is nothing except for the screw that holds it, so just pull on it). Here is what it should look like with the bottom cover off.
The front bezel is tougher. Pull off all knobs (be careful not to lose the little felt washers/seals in the volume/squelch knobs). The VFO/memory knobs have ordinary hex nuts on them, use longnose pliers to gently loosen them up and then a jeweller's screwdriver or some such to unscrew them all the way. The small knobs have round collets with two slots. I didn't have access to a (spanner?) wrench that would fit the slots, so I took apart a small "binder clip" to make this contraption, which worked very well.
The front face is now pulled off after gently prying up a rectangular tab on the bottom side (it mates with a small protrusion in the chassis) and also pushing down a bit on the top side, where there are two similar tabs near the sides and under the top cover. Just wiggle the whole thing while doing it and it will slide out. This is how it looks.
The logic board holds the pushbuttons, two encoders and the LCD, and is just plugged into two sockets on the main unit. When you are remowing the bezel, the logic board might come out of the sockets along with it. If not, grab the PCB near the edges of the LCD and gently pull it away from the main unit, rocking it a bit. There are no screws or anything holding it except for the friction of the sockets and guide pins that stick out of the chassis. Here's the logic board detached from the main unit.
By the way, I noticed that the previous owner did a mod to open up the transmit by cutting a jumper marked W1 next to one of the sockets. I don't want that, so I soldered it back together. You may want to check yours.
A few more pictures. I decided to take the LCD module off of the logic board. Prying the metal clips that held it gently to the sides and squeezing the metal "barbs" in them let me carefully slide the sheet-metal frame and the white plastic enclosure out of the PCB, without the module coming apart. Here is the front of the logic board (normally hidden behind the LCD): right (UHF) side and the left (VHF) side. For good measure, closeups of the back of the board: right (VHF) side and left (UHF) side with some discoloration on front and back of the board near the transistor Q2 which supplies power to the backlight lamps. I guess it's normal, but the lamps must have been working overtime. I always crank my backlight down to medium level.
