No guaranty, but ....
Using the RCA RCRP05B ($20 at Best Buy):
Over at hi-fi-remote.com, there are 2 files for Proscan TVs.
The 42LA45H (similar model number to yours) controlled with setup code 2183 (NEC1 device 4)
32LB30Q by 2256 (NEC1 device 160)
For Soyo, there are 4 files
MT-SYTPT3727ABMS and ACL32 // PRTPT3208NB by 1826 (NEC1 device 9)
DYLTO32A by 1546 or 1765 (NEC1 device 3.172)
MT-SYKIT32E1AB (no code, keymoves would be required) (NEC1 , device 128)
None of these are an exact match for your TVs, but I suppose that the odds are pretty good that the RCRP05B would work for both.
