Thanks. Can you please get me the model number off of the back of the Sanyo? Also, how long have you owned it for?

What exactly happens when you try to switch the Input over to HDMI 1 or 2? Does the TV let you select it, but simply doesn't show a signal?

Attached is photo , and it won't recognize hdmi 1 or 2
Customer: replied 1 year ago.
Meaning it doesn't even give me those options when I have a cable plugged into them

DP50710.

Age of the set and when the issue occurred please?

Customer: replied 1 year ago.
It just occurred I unplugged it for a few days to paint and when I plugged it back in
Expert:  Aric replied 1 year ago.

Thanks for the reply. This typically indicates the Mainboard has a fault on these ports- requiring replacement of the board, or the EEPROM (processor) has locked up.

Please shut the TV off, then disconnect it from power. Remove any HDMI cables from the set, then press and hold the power button on the TV itself (not the remote) for 15 seconds and release. Wait a full minute then connect an HDMI cable to HDMI 1 or 2. Plug the TV back in and turn it on. Let me know if you have the same problem.

This didn't work, I did have the hdmi cables still plugged into the Xbox and the direct tv box but not the tv. Followed directions and same result

Okay this is a fault in the Mainboard- and sorry there's not a quick fix or way around this. If you're looking to repair the set yourself, you will need to purchase part number: Sanyo J4FL (1LG4B10Y04600_B).

Ok thanks

You're welcome. There's also the workaround of using an HDMI switch, or repairing by sending the main to Coppeli for a swap below:
