If the DVD was not doing this fault when new, then this is not an update
issue. It would be a new defect that developed over time. This can be
anything from corrupt firmware to a cold solder connection, or some
component that is failing.

You will need the service manual, and proper tools to troubleshoot your
player. Generally, when these are under warranty, the service rep changes
the complete board, and or defective assembly, and discards the old one,
when these types of problems occur. He then follows up on the alignment
procedure according to the service manual to complete the job.

The replacement costs of these players is not very expensive in relation to
the labour and parts when servicing these. This is why it is rare that
board level, or hard troubleshooting is not done. It is rare that on these
players there will be any service bulletins, unless it is a very high end
model that pays to work on. The cost of the service manual alone can
approach the cost of a new machine. To fix one machine this would not pay to
invest in. The required test equipment for servicing these is also very
expensive.

Hi,

If anyone on this news group have SONY DVP-S7700 service bulletins which can
e-mail to me. My DVD player locks up sometimes when watching VCD when doing
searching. It needs to press stop button and re-play again. I talked to
SONY and they have very poor services. I bought the service manual but they
won't provide service bulletins for update. It is kind of stupid to fool
customer if any design problem such as the famous TA-E9000ES. SONY try to
hide every design problems to their customer. From this experience, I will
get away all SONY products.

Thanks

Eric

What kinds of VCDs? Stuff that was press-replicated at a disc pressing
factory, or something that was burned on a computer?

The DVP-S7700 uses a dual discrete pickup, meaning that there are two lasers,
one with each objective lens, with one calibrated for DVD and the other
calibrated for CD.

Replacement of this part will be expensive if it is defective, but I'm willing
to bet that the VCD you are trying to play may have been recorded at high speed
using a computer writer. If you still have the CD image of this VCD on the
computer, burn a new copy at a slower speed. If not, try to copy the disc on
your computer, but, again, record the copy at a slower speed. Copy the
original as an image file, and then copy off the image. Burn no higher than
8x.

Problems with DVD players playing VCDs made on computers is not uncommon and
primarily due to the fact that the burn was done too fast. - Reinhart
