In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.
Why do "we" have no sound?
Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Make sure the signal cable for the input you are using is tight. Possibly try a different cable. Especially if you are using the Red Green Blue component cables. Make sure the issue is across all inputs. If so, try adjusting settings for tint. if that doesn't help you may need to replace the TV.

Have you tried to reset the remote? To do so, press all the buttons at once & hold for a few seconds. You can then re-program your remote to the TV. Also, you can try to power cycle the TV by unplugging it, leaving it unplugged for a few minutes, and plugging it back in & restoring settings back to factory defaults. This should resolve the issue.
TV won't display anything. Screen goes white.
I would recommend pursuing repair options with a licensed service technician, as most likely this is caused by a hardware malfunction. Bear in mind, repairs may not be cost effective, and therefore, may be cheaper to pursue replacement TV options.
Dx l-32 main problems
I see so many here with no sound/no picture issues: ISSUES: 1. IF sound main fuse/s are good. 2. If no power or standby check main fuse, standby power supply and any signs of damage you can see---burnt parts etc. 3. almost all these sets the troubleshooting involves checking
voltages on the main power board to narrow down the problem. 4. Be safe and if you do not know what you are doing don't open the set. Answers to issues: 1. RE:fuses---if a blown fuse is found get a good replacement(not the generic ones like Radio Shack). Many fuses are special even aside from amperage--Don't put a higher rated amperage fuse in the set for any reason. 2. RE: power supply in set: if total dead aside from main fuse the set uses a standby power supply that runs 7/24 and a main supply (some are combined and some not. Here aside from checking fuses you want to examine all the filter caps on the power/standby to see if any are puffed up or buldged up in some fashion--I attach a photo of a good one---top should be silver metal and PERFECTLY flat and have no brown material coming out on top or bottom. What happens in the standby area is they use caps with too low a voltage rating (saves money) which causes them to fail in a year or two---the standby runs 7/24 and the heat dries out the caps and they fail. 3. Trouble shooting consists of the above and then at some point you have to buy and try a board to see if it fixes it or not. 4. Safety first--no TV set is worth getting injured or even killed over. If set is opened at least look for puffed up and bad caps like in this photo.
