If you are connecting a computer using a HDMI cable, the audio does not go on the cable. You must use a stereo audio cable to connect the TV to the PC.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should troubles shoot. Contact any service technician. The circuit will differ with models and versions.

Change the batteries first. Then see if you can turn on the TV using the buttons on the TV. If the TV still works then best get a universal remote. I really like my Harmony brand.

Each manufacturer creates their own codes, so you will have to look at the manual for the Comcast remote, or on their website.

Check the fuses

If panel lock is being stetted to ON, the front panel buttons on the TV won't work. If you want to make it a system reset, you have to enter its service mode option.

This is likely a simple settings issue. A lot of people don't realize that backlight settings can affect the picture. Go to the menu (press menu on your remote) The menu will show picture options. Just toy with different settings until you find what you want. It may be on a preset setting that doesn't work. If you are in a bright room, you will need to increase brightness and contrast and perhaps backlight. Usually an unclear picture is due to the contrast, backlight, and brightness settings being too low. You can also increase sharpness. I suggest a contrast setting of 70, a brightness setting of 60-80, and a backlight setting of above 80. Good luck.,

These are all the codes. It is better to buy a remote specially made for that model. Read this https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote
