problem with philips DVD612

[Mickael Lorgeoux]

Hi,
I have the DVD player philips DVD612 since 3 years, it worked well up to
few weeks ago.

Now, after around 30-45min of DVD disc reading, the image freezes and
the message "disc error" is displayed. After that it is not possible to
re-start the reading, even after an on/off.

I have clean up the lens of laser diode but it has no effect... It may
be a heating problem but what to do??

Any help is welcome.

It is possible that there are some parts becoming temperature sensitive. One
way to locate this is to get some freeze spray (liquid air), and a heat gun,
and try to provoke the problem by heating and cooling suspected parts. Care
must be taken doing this procedure.

Another approach is to purchase the service manual, factory test CD, the
proper scope and DVM, and trace through the various stages following the
service manual, and troubleshooting the unit when the defect condition is
happening.

If you are not trained, equipped, and experienced to do this type of
service, it would be best for you to give the unit out for an estimate, so
you can make an intelligent decision about having it serviced. If it is a
low cost player, it may be more worth for you to simply replace it.
