JVC VCR Remote Multi Brand Remote LP20303-008 READ (3 Buttons Not Working)

The "Tv", "Cable/DBS", & "MBR SET A/B" Buttons do NOT work (see last pic). These buttons worked 2 times while testing but then never worked again. Not sure if there is a short on those buttons or not. All other buttons tested & work. Really good condition remote. No corrosion in battery compartment.
