If your television is experiencing HDMI troubles including no signal and distorted video, see the Insignia NS-24ER310NA17 No Signal With HDMI problem page for possible causes and solutions.

The XBR line is superb.

Bad, bad luck on the HDMI-1 port - that's an easy mistake to make. Troubleshooting the component level on the circuit board is not fun.

But given that these units are still available as refurbished for about $1,200 USD, it may be worth repairing.

If you are a tech or an advanced hobbyist with workspace, and proper test and repair gear, and access to parts, and repair manuals, you could take a whack at it.

Otherwise, it may still be worth paying the $100 USD diagnosis fee at an authorized SONY repair shop.

With time and materials, I would guess your total bill for out-of-warranty repair would be about $250 USD (including the $100 USD diagnosis fee) if the problem is isolated to the HDMI interface.

It would bug me not to have that port working, so I fully understand why you would like to fix it ! Best wishes and hope this beautiful set gets back on its feet soon.
