Eddie:

When I 'activated' my DVI cable last Nov.

on Time Warner Cable..... My HD channels were

a little slower to switch both mode & Channel...

SA3250HD Cable Box & Sony 34HS510 HD set used

a 2 or 3 second time delay to both figure out and

post on the TV screen 1080i or 720p or

a 'bad' guess like 480p.....

I has to program the SA3250HD Cable box for 6 of

6 options that my Sony accepts: Box default is 1080i...

1080i, 720p, 480p wide, 480p, 480i wide, & 480i....

I never had any Time Warner color changes except

during TV set Power up from a 'cold start'...

You wouldn't happen to be watching a Sony XBR or HS series HDTV would
you? If so you'll want to check out this link.

I would definitely leave adjustments in the service menu to a VERY
experienced Sony technician. If you happen to mess up the wrong adjustments
you can actually do damage to the set. Also, the problem that you describe
might require parts to be replaced. The procedure supplied by Sony needs to
be well understood for diagnosing and correcting the problem.

No problem as long as you pay attention to what you are doing and, like you
said, follow the steps exactly. We have seen people reset the EEPROM an
corrupt the data in ways that make it very difficult to get the set to start
up again. You have to change the EEPROM and reset everything.

The company I work for is a self servicing dealer and ASC for Sony. Whether
you voided the warranty or not depends on what you did and what problem you
report. If you change settings in the service mode that cause a problem,
then you may not get it fixed under warranty. If you ever have the set
serviced under warranty, I would put the settings back to the original
values.

Generally, as I said, it is best to stay out of the service menu unless you
are very comfortable with what you are doing and know the system well.
Tech's sharing stories frequently talk about how the business of
"decalibration" is brisk.

In your case, I wonder why you did not have the service performed under
warranty. Did you at least know what to look for to verify that the B board
was the updated version?

You might check your warranty. I thought it covered in-home (or pickup)
service for that size. Frankly, I never paid much attention, we just
automatically treat any set that size as such for warranty repairs.

I also learned a long time ago that manufacture dates and serial numbers
don't always tell the whole story. I have seen wrong info from
manufacturers more than a few times. I'd always check the board to be sure
it is the updated version.

I did the simplified "fix" changing the hdpt from 1 to 0. No scrolling
bar. If I recall correctly, the wrong B board after making the hdpt
change would have left you with no picture (blank blue screen?)So
Eddie and myself have, by info provided by the AVS thread the correct
B board.
