Found this TV on craigslist, it is very cheap because there is an issue with it.. I haven't bought it but I'm wondering if anyone has some insight to the problem or if they know how much I should expect to pay to have it fixed.

The seller says when he turns the TV on everything works fine for about 30 minutes and then the screen just goes black, he mentions the bulb is almost brand new so that shouldn't be the issue..

The TV appears to be in great condition and I would like to take a chance on it but it's about an hour away from me and I don't really want to end up spending more to fix it than if I bought it new

Thanks ahead of time for any help

Since it is a 720p DLP the owner should be happy to give it to you get rid of it since it has a problem which could costs hundreds of $ to repair and after that it could fail again and cost you more money to fix since it has no warranty.
You can buy a brand new 50" full HD 1080p HDTV complete with warranty for about $1k.

Thanks, that's all I needed to hear.. Just figured for $75 it might be worth the risk but not going to drive 40 miles both ways if it's gonna cost me hundreds in the long run

Could be the Digital board which is like $250. But should be diagnosed by a tech.

Could be the ballast.

Could be the ballast. Ya, depends if the lamp stays lit while the picture goes "black". Also does Tv shutdown? or stop responding to remote commands? or happens on all inputs? or can/cannot see Tv menus? Lots of possibilities...

Can anyone help? I have a HLN5065w it is 4 1/2 yrs old. it now has a red tent to the screen what could be this issue? the color wheel?

Probably light engine! just fixed mine same problem but it is a $600 fix. Mine was still under extended warranty so I would just buy a new one
