I have two BD-UP5000 players.
Only one of them tends to freeze after 10-20 minutes of playing a Blu-ray or HD-DVD once I start it. The picture actually freezes on the screen and all controls but Power do nothing. Once it freezes, I have to power the unit off then back on in order to continue playing the movie.
Once I do this, it will NEVER freeze again...even if the rest of the movie is another 2 hours or I play a 2nd or 3rd movie afterward.
It always freezes after a short time of playing the first disc after powering on.
This was really bugging me (and the family!) so I decided to try and see if I could get to the root of the problem.
At first I didn't believe it was heat related due to it only freezing during the first 10-20 minutes and never after that. I figured that the more time elapses, the hotter the components will get, and the more likely lock-ups would reoccur.
Well today I took the cover off of the unit, powered it up, verified that the internal fan was working (it was) and started playing a Blu-ray with the cover off, and guess what, no freezes at all during the 3-hour movie!
Now I'm thinking that the issue may be heat related after all. There are two chips (processors) that get quite hot during operation in this player. One is covered with a black aluminum heatsink and the other is the ReonVX chip.
Since I don't want to leave the cover off permanently, I decided to look for another solution. I picked up two heatsink/fan combos to be installed on the chips i mentioned previously. They are only 1.5 inches square and 1 inch tall. Perfect size for this application. The fans use 12VDC which I can tap into off the power supply board in the unit.
When they come in, I'll install them and let you know if that permanently solves my problem.
I know that some of you out there have said you have the same issue with your player.
I've attached a picture of the Heatsink/fan below.
I hope this works!
