The tv has sound but no picture when turned on, but after a couple of hours, the picture shows, and everything is fine. We were told it was the motherboard and it would cost 400$ to fix it. What is wrong?

It is either the motherboard or DM/convergance board that has bad capacitors. It is very common for the motherboard's capacitors to burn out in the newer televisions

Crack the screen on tv can it be replaced

The short answer is yes, but in reality, the replacement cost of the panel could exceed the cost of a new TV. Call HP to get the panel cost and make your determination. The actual replacing of the panel is relatively simple and any shop should be able to do this for you without a high cost.

Another Mintek Question...

To my knowledge this is not an issue that can be fixed completely without obtaining a new motherboard/DVD player and replacing them altogether. Another member, Ori, posted that it might be possible to trace the handshake signal the built in DVD player uses to communicate with the TV's motherboard. The correct signal would "unfreeze" the motherboard allowing for a fully functional TV. Unfortunately I haven't the time or skill to do that.

As far as the availability of replacements, I have seen the whole sets go on ebay quite frequently, but they are usually ones that have this same problem. Apparently Mintek went bankrupt some time ago per what little information I was able to find out about them, so that cuts any hope of a new replacement as well.
