I have one of these that looks like it's in mint condition except the screen has a oval black blob radiating about two-thirds from the center of the display. I have no idea how to fix this, but I think the LCD actually needs to be replaced on mine.
A black blob in the middle of the screen sounds like the liquid has come out of the containment area of the liquid crystal display and yes, the screen needs to be replaced. In every other case I’ve seen of a repairable display the screen looks perfectly blank and clean when the radio is off. When you turn the radio on it can be anything from blank to garbage characters to vertical lines or other things like that. But a black blob is a failed display.
Donor radio will be your best bet. Some parts are available at PacParts but looks like the LCD is discontinued. www.pacparts.com/model.cfm?mfg=kenwood&model_id=TH79A&action=list_part&mode=auto&back=0
@@rjmorgansd Yep, I checked there a while ago, unfortunately nothing available., That's OK - it's been sitting on the shelf for a few years already, so what's another few? Lol! :-)
Great video! Now all I need is a TH79A....
Well if you get one at least now you know what the insides look like!
I remember fixing mine for that 15 years ago. Sure they must all do it.
Great video Robert. What a smart & talented fellow you are!!

@@rjmorgansd Yup, so now I wait until I find a donor radio somewhere that I can salvage an LCD from. :-)
