RE: PHILIPS DVD 703 - BLOCKED
Something I forgot to write last night. I also removed the flexi circuit connecting to the laser assembley, so not only would the laser not function, but there would be no way whatsoever that data from the DVD/CD could be read.
It acted exactly as described in my first post. So my conclusion here is that there is something not quite right with the drive circuit/motor.... maybe there`s a current sense circuit somewhere to detect ho much current the spindle is taking. Maybe the motor is now just taking too much once it has a load (DVD/CD) on it??
I am open to other theories, but I still reckon it`s a HW not SW problem.
I will get in touch with Philips eventually. I used to work for Philips Semiconductors for quite a few years, so I still have a few contacts that may be able to help....

RE: PHILIPS DVD 703 - BLOCKED
The Fault can also be replicated by slowing down the spindle!!
I sumise that with the mass of the disc on the spindle, it is not spinning up to speed quick enough before it times out. If you look at how the disc spins (without the DVD cover on) it certainly takes its time. Either the motor is wearing out, or the drive electronics is not driving the motor with the correct drive. A more likely explanation than a spurious SW bug that cannot be cleared.

RE: Philips DVDr610 BLOCKED message
Hi All,
I`ve just got hold of a Philips DVD751 from my brother in law with exactly the same problem as being described here. This IS a hardware problem. I haven`t completely located the fix for it yet, but I have narrowed it down....
With the cover off It`s possible to see exactly whats happening. When you insert a disc, it spins up but is ejecting before it reaches full spin speed (before the laser comes on). However, if you reset the player by unplugging it, once turned back on, close the draw without a disc in. The motor spins up to full spin speed almost imediately and the laser springs into life looking for a disc. It does not eject!!. The problem can be replecated whilst there is no disc in the draw, by touching the top of the spindle and stopping it going round, the disc draw ejects!
This leads me to believe the fault is located to either the drive motor that spins the disc, the power supply supplying the power to the drive circuit, or the sensor which senses the speed of the drive motor (or disc spin speed).
I`ve yet to do more experimenting, but I will post the solution here once I`ve found it. Hopefully it won`t be too long, but with a new baby, and new house it may be longer than I hope..... If there are any other repair engineers out there who want to carry on with the fault finding, hopefully the above is helpful!
