Probably a job for a camera technician. Could be just a connection, but, OTOH, they might be part of a printed circuit board, in which case it may need a spare. Depends obviously on the availablity of parts, or if a defunct doner body is available.
I use Pentax MX and LX bodies and their great solid little cameras. If the body is very cheap and otherwise sound, and if you could use it without the LED's working properly, it might be worth a punt, but I'd probably budget for a CLA anyway if I were buying another body of that age.
