old DLP TV

So my buddy gavw me a free tv in hopes that I could fix it and use it. So far after a new bulb, replacing some bulging caps and disableibg the lamp temp sensor it wont stay running. My question is what all is inside these tvs lens/mirror wise? Anything that would be fun to mess around with? Or just sell it as is and make a few bucks. I already plan on selling the new lamp to make that money back.
