Post HDMI / LG problem
Hi,

I have been using an LG LCD TV - 22LS4R which has an HDMI input successfully for 9 months or so with my fit-PC2, but last night the picture just disappeared.

I connect using a standard HDMI to HDMI cable.
I have 3 cables and have tried all of them.

I was connecting a LAN switch and wanted to get into the bios to activate the LAN card. When I rebooted the computer I forgot what key to press to get into the bios and the bios screen never had time to appear before the Windows screen came up. I rebooted three times and tried pressing ESC and F3 several times on startup. On the fourth try the TV just showed a "No signal" message and I have not been able to get it to work again.

The TV works when connected to another PC using VGA - VGA and the input set to RGB.

The TV does not work when connected to another PC using a HDMI to HDMI cable.

The TV works as a TV.

Could the repeated reboot (3 times) while pressing F3 and ESC possibly have destroyed the HDMI circuitry? sounds strange but strange things do happen.

I don't have a VGA converter.

I am based on a sailing boat (currently in the Red Sea) and don't have access to much computer equipment for testing or any repair facilities.

I would expect that sea air does shorten the life of contacts, so this is something you may want to lokk at more closely.

To get to BIOS screen press F2 at power-up. This should always work regardless of SW corruption, but note that some TVs do not support this video mode (640x480@60Hz). If you have ever seen this mode on the LG TV you should see it every time as long as HW and cabling are OK.

I have been viewing the bios on the LG TV screen before.

The HDMI port on the TV no longer works that is clear. I have tried to connect it to two other computers with the same result.

I explained about the bios because it was when trying to get into the bios the HDMI port died. It was perhaps just a pure coincident but I wanted to check.

Reading various TV threads it seems as if the HDMI ports often fail on modern TV's !!! A real pity for people that have forked out 70-80 Euro on an expensive super duper wonder HDMI cable, he he.
