Have TV Questions? Ask a TV Technician
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Can you check the model number for me? It is likely something like WS-65819
Please recheck those remote numbers as well, as that is not a valid part number. Where did you get that remote, did it belong to a different mitsu tv?
Thanks for the info,
the first issue here may be with your box. If your cable box only has a hdmi output, it isn't compatible with this tv.
If you're using the red/white/yellow cords from the cable box to tv, you need to set the tv source/input to the VIDEO mode.
If using coax from box to tv, then you need to get into the menu and run the auto scan (auto program) function, then after that you can set the tv to channel 3 or 4 to pick up the box signal.
I do have the manual, and have uploaded a copy for you here: https://dl.dropboxusercontent.com/u/29960072/L0306250.pdf
That actually is the proper remote, but it comes preset to operate this tv. It can't be programmed for other tvs, it either works or doesn't (if it doesn't the remote may be faulty or a problem with the tv).
Try making sure the slider switch at the top of the remote is in the TV position.
