Well, it looks like I found the cause of my freezing issues.
If you recall from previous posts, my problem was that one of my two BD-UP5000 players would freeze anywhere from ~7 to ~35 minutes into a movie. The only recourse was for me to turn the player off, the back on again, and go through the agony of trying to pick back up where the freeze occurred.
This would only happen when I would first turn the player on after it had been off for at least a few hours...on the first disc I played. After the power off/on, it would play just fine for the duration.
I ran some experiments to see if it was heat related and I found out it was.
Both of the large processors on this unit run extremely hot. This would be the Main Processor and the Reon-VX chip.
My solution cost me about $10.
I purchased a 40mm x 40mm x 28mm "Chipset" fan and heatsink assembly.
This is a 12 Volt DC powered fan rated at 5 CFM.
I disassembled the fan from the heatsink and installed the fan on top of the existing heatsink on the 5000's main processor. This is a three wire fan but only 2 wires are needed (Red+ Black-) so I clipped the third wire. (Yellow)
The Red and the Black wires were tied into the 12 Volt DC supply on the 5000's power supply board.
I then attached the fan to the top of the existing black heatsink so that it would be blowing air down on the fins.
The gold-colored heatsink that came with the fan (that I disassembled) was installed on top of the Reon-VX chip to help cool it down as well,
The Reon never had a heatsink on it to begin with so I decided it could use some help too. I decided not to install a second fan on the Reon because I didn't want to load the 12 Volt power supply down too much.
I've run through several tests now that are identical to my previously stated testing with the player's cover on and have yet to have the player freeze on me.
By the way, the underside of the main circuitboard opposite where the main processor is mounted has a thick gray silicone heat transfer pad that makes contact with the board on one side and the inside bottom of the steel sheetmetal chassis on the other side. This is there to draw more heat away from the main processor. This heat get transferred to the sheetmetal case on the bottom of the unit.
Before installing the extra fan, this bottom area under the player would get extremely hot as well but after the fan installation, it is only warm to the touch.
I've included some before and after photos below.
I'm posting this because there may be others out there with a player that behaves like mine did (with the freezing) I hope this helps you too.
