How can I tilt the picture of a JVC AV-29 BF11 ENS?

[Cef]

Hi, I need your help. I just purchased a JVC AV-29 BF11 ENS. Unfortunately, the picture is tilted slightly to the left. How can I rotate the picture? I found out that the service menu can be accessed by pressing "i" and "mute".

The service menu contains the following options/settings:

OSD 052
IF1 005
IF2 068
IF3 003
IF4 062
AGC 053
VLIN 007
RGBH 008
VSOF +03
VPOF -01
HSOF -02
HPOF -05
HTOF -02
WR 036

OP4 00001000
OP5 00000000
TX1 01010110
GEOM 00100000
OP8 00000100

Once in the service menu, pressing the green button brings up another menu, titled "Geometry", which has the following options:
VSIZ 057
VPOS 019
VSCO 003
VCCO 007
HSIZ 019
HPOS 032
HPIN 008
HCCO 011
HTRP 012
VZSZ 006


I could not find another menu. I have tried changing several of the settings, but none did rotate/tilt the lines.

It's not possible to rotate the picture on JVC sets unless it has the option in the normal user menu. This is usually restricted to the larger widescreen sets.

The only way to do it on sets that don't have it as a user option is to loosen and rotate the scan coils or use stick on magnets. These should only be attempted my someone who knows exactly what they are doing.

Thanks for your reply. Guess I'll have to carry it back to the store then (damn, it weighs more than 50kg!)

It's worth speaking to them first to find out if the amount of tilt you have is within specification - a few mmis allowed. It's also possible that the tilt you have is caused by the Earth's magnetic field. Try turning the set 90 degrees to face a different direction and see if that improves things.

It's approximately 4mms- not very much but noticable, especially when watching widescreen movies and looking at the black borders. Turning the set doesn't help.

In case anyone cares, I called JVC about the problem and they recommended I return the set and get a new one, which I did. The new set has no tilt and is working great! Brilliant, crisp picture, good sound. Highly recommeded.

One interesting note: The new set has slightly different settings in its service menu; seems each tv set is calibrated individually.

They are indeed. each set is loaded with standard values and then these are tweaked during final adjustment at the end of production. These are all the usual stuff - Height, Width, Position, etc.

By the way, which country are you in? The AV-29BF11 is not a UK model so I assume you're elsewhere.

I bought it in Germany. I chose it because it can play NTSC (real NTSC 3.58/4.43 and not just PAL 60) and has a flat screen. It was pretty affordable, too; only €300 (=GBP 200). Not too long ago, a set such as this would have cost twice as much (in the UK it would probably sell for more than GBP 200 since prices are higher there in general.)
