When new that unit sold for around $2000 and $3000. But that is an older unit and you'd be lucky to get $500 for it now. It was manufactured in 1996 making it 13 years old.

This company tears down a broad variety of TVs so enter your model number there to see if they have one on hand:
They do warranty their stuff to be operational.

might wish to unplug the TV for an hour or more. If this power reset
does not allow the TV to turn on component failure is indicated. These
sets are assembled using the wave soldering process they are known for
having cold solder connections.
The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad.
This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced.
The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.
Black Screen - Sometimes, the TV may display a black screen, now you need to check the cables whether they are properly plugged or not. Reconnecting all the cables can also work for this problem. Also, if the screen has a screen saver, check how it's set up. And, if nothing works for this issue, then there is a possibility that the lamp, rear projection, or the LCD panel may have been damaged. Now, you need to check your warranty card of your television and se your set comes under the manufacturer's warranty period. Call the customer service for technical problem and get replaced if a part demands it.
It can be overwhelmingly frustrating when an electronic device as expensive as an LCD television set starts having problems. Luckily many of these problems are easily troubleshot. While being able to hear sound coming from your LCD television but seeing no picture may seem serious on the surface, fixing the problem involves checking a few different settings to make sure everything is set properly
Check the video connection of any devices plugged into the LCD television. If you can hear sound but are seeing no picture while trying to use something like a DVD player or cable box, the problem is probably that a wire is loose somewhere. Check the yellow video cables running from the DVD player to the TV and make sure everything is plugged in firmly and where it should be. Also check the coaxial cable running from the cable box (or cable outlet) to the television and make sure that wire is also screwed in securely.
Check the image settings on your television and make sure everything is set properly. Certain settings like "Picture" or "Brightness," if set to one extreme, can make the picture appear completely black. This could cause you to simply hear television shows but not be able to see them. Reset all picture settings on the TV to their original factory default settings to see if that fixes the problem.
Try another channel. If you're watching TV and not getting a picture, the first thing you should do is check a variety of random channels to make sure it is a problem with your TV and not with your television signal. If it is a problem with the television signal it is the fault of the TV station or cable service provider and there isn't anything you can do yourself to fix it.
Try the DVD on another DVD player. If you're trying to play a DVD and can't see any images, make sure the disc isn't defective. Try it on another DVD player or a computer DVD drive and make sure the disc works in the first place.
Hope it helped ..
