try other types of media- it's possible there's a malfunction in the motor drive electronics.

Hi Dengle

The heat is caused by IC001 which is a regulator that is mounted on a completely inadequate heatsink on the power board. This component gets very hot during normal operation.

The regulator will usually last a couple of years, depending on how often the machine is used and then start playing up. The symptoms are intermittent operation, continuous self checking and rebooting, not being able to read discs and so on.

Eventually the component can short-circuit, burn out and take other components with it. The on-board fan is thermostatically controlled. It does not operate all the time, only when the unit gets hot enough. By using an external fan, you are keeping the unit cool enough for its own fan never to cut in. The additional cooling is probably squeezing a bit more life out of the regulator and is stopping its own fan from operating.

I have repaired lots of these and have never found a faulty fan, or fan switching fault. There's always a first time of course.

It is more likely that the regulator IC001 is faulty and if you are technically skilled, I would suggest you seriously consider replacing it. Use some heatsink compound and an extra heatsink, and it will probably do the trick. The regulator is an STRG6353. You can get these easily online from a number of outlets. Don't attempt a repair if you are unsure of what you are doing. Regards..

unfortunately, this unit is on system lock down due to massive main board failure. its kinda like a system protect mode. this can only be repaired by the manufacture or maybe an in house tech with knowledge of the board outline. i don't think this unit has an escape code for retrieving the dvd. hope that helps ya and thanks for using fixya:)

In an unit of this age the first thing that fails is the power source (more specifically the filtering capacitors - they start to dry out), especially in a unit like this, with very little space inside for air flow and big consumers that generate a lot of heat.
If when the source has failed nothing else was damaged the fix will be quite simple and easy to do and al the replacement part will cost less than $40. To that you must add the labor - that depends on who is going to do the job.

Same problem here and this is what fixed it. Plug the LAN cable from your modem to the back of the blue ray player. Press the setup button on the bottom left of the remote. Goto the "Others" option and select firmware update. It takes a few minutes, but will install the appropriate updates and you'll be g2g.
