HDMI problem on RP JVC
jordo
year ago. It works fine except for the HDMI input. When I plug it into my
cable box and switch to the digital input, it can't detect anything (and
says it's gonna turn off in 9 minutes if nothing is connected before then
:)). However, if I plug in my computer via a dvi/hdmi cable, the tv still
doesn't detect a connection, but the computer recognizes the tv for the
model number that it is. There is no setting in the tv that can affect the
input, from what I can find (and I went over all the menus multiple times).
Any ideas on what might be causing this? If it's an electrical problem, is
it worth my time to get an electronic technician to fix it?

Dunno if it's any help, but my Sagem DLP detects any of the many inputs
coming alive and switches out of standby - except the digital one which in
this case is a DVI type.

doesn't show up anywhere. I was reading on some forums that the HDMI
can be disabled by various things and that it can be re-enabled by doing
a "system" check in the service menu (and it gives the steps to do
that). However, I cannot find the steps to get INTO the service menu!

Wonder if it's tied in to a component input which could be either
component or RGB? My sat receiver is like that. Select RGB and you loose
the upscaling, etc.

Has the TV ever been serviced? I've heard that some Pioneer TVs are
booby trapped so that if the set it plugged in with the back cover
removed, it disables the HDMI input. They are worried that you might
be trying to steal Hollywood movies.

it's been serviced before since I got it second-hand. I'm thinking that
might be the case and can reset it, but only if I can get into the
"service menu", which I can't get into because I have no idea how to. :)
I've looked online to try to find out how, but no luck so far. :S

No stupid. If that was the case then the T.V. would say "Incompatible Input
Signal" or some shit like that.

make sure that its resolution setting is within the range of the set. If it
is out of range, the set will act as if there was no response.
I have also seen a failed HDMI port on some equipment react in a similar way
that you are describing. But, first investigate properly before coming to
any conclusions.

To recognise the TV, the computer only needs to be able to read the
TV's EDID EEPROM via the DDC pins in the cable (pins 6,7,14,15):
http://pinouts.ru/VideoCables/hdmi_dvi_cable_pinout.shtml
I have managed to read a powered-down monitor's EDID EEPROM using my
device programmer. I made a VGA DB15-to-DIP8 adapter cable and told
the programmer that it was connected to an Atmel AT24C21 serial EEPROM
which has a "DDC1/ DDC2 Interface Compliant for Monitor
Identification".
You can find the EDID in the registry at the following key:
HKEY_LOCAL_MACHINE\Enum\MONITOR
If you export that key to a .reg file, you will see the EDID EEPROM
data. Analysing the EDID will tell you what scan rates the TV
supports. FWIW, if you post your EDID here, I may be able to analyse
the data for you.
BTW, if you want someone to help you, it would help them if you would
indicate the TV's model number.

to get the registry info for you. The TV is a JVC AV8P575.

Page 68 of the user manual ...
http://resources.jvc.com/Resources/00/00/95/YA091ien.pdf
... states that ...
"The Digital-In [HDMI] terminal is not compatible with picture signals
of a personal computer."
I'd try a HDMI equipped DVD player.
In any case it still might be interesting to see what the EDID EEPROM
contains.
BTW, I believe your model is AV48P575, not AV8P575.
jordo
Yes, my model is the 48" version. My keyboard is on the way out and
sometimes keys don't work..:)
I knew that it wasnt supposed to hook up via PC, but it was the only
other option I had. I have also tried to hook up my cable box, but no
success.

By way of example, here are the EDIDs for my LG 32LC7D TV:
http://www.users.on.net/~fzabkar/EDID/
The phoenix.exe utility analyses the EDID .dat files. Switch off
read-only mode for a better view of the data.
Phoenix.exe sometimes hangs on my Win98SE box. I don't know if this
problem occurs in other Windows versions.

It's possible that the cable company has HDMI disabled for some
reason. It's also possible there is a HDCP compatibility problem
between the cable box and the TV. Even in my own home, I've had
several situations where a particular HDMI source just wouldn't work
with a certain display. HDCP is well known for having bugs.

it up via HDMI and called back to the main place to make sure HDMI was
enabled on the box. When it wouldn't work, we just went with component
which worked right away...

I don't have a registry key called Enum under HKLM...I'm using Vista,
btw...that probably would've helped, eh? :)

I hope you are aware that JVC booby-traped the DVI modue in this set to avoid
tampering. If you remove the back without taking precautions say bye to your digital
input. See: http://www.iwaynet.net/~nesda/Jan04/Jan0413.html

second-hand, so it could have been serviced in the past. However, there
is a way to reset the HDMI module from within the service menu (you do a
self-check, then turn off the tv from within the menu and unplug for 30
seconds, according to a few forums I've read). However, I don't know
how to get into this service menu.
Steve
Thats not what I was told by JVC, but if you think it will fix it give it a try;
SERVICE MENU setting
a) Press [SLEEP TIMER] key and, while the indication of
SLEEP TIMER 0 MIN is being displayed, press
[DISPLAY] key and [VIDEO STATUS] key on the
remote control unit (Fig.2) simultaneously.
b) The SERVICE MENU screen of Fig.1 is displayed.
c) Verify what to set in the SERVICE MENU, and set
whatever is necessary
Be very careful NOT to change any settings if you don't want to create a
boat ancor.

A great idea just popped in my brain:
How's about you tell him what settings NOT to change if he doesn't want to
create a boat anchor.

Tell me what cable box outputs a 1080p signal, dim bulb? Nobody broadcasts
in 1080p, you can only get it from a Blu-Ray disc, stupid.

I'd just search the registry for "EDID" or "monitor". The data have to
be there somewhere, unless Vista decodes the EDID, stores the
supported scan rates and resolutions, and then discards the raw data.
Franc Zabkar
Have you tried setting your PC's resolution to 640 x 480 and
experimenting with different refresh rates, eg 60Hz ???
Can you at least get into the "digital-in" option of your Initial
Setup menu? If so, then according to page 47 of your user manual, this
would confirm that your TV is receiving a HDMI 480p picture signal at
the Digital-In terminal.

Do you have a circuit diagram of the HDCP/HDMI module?

What the fuck are you smoking? Show me where I bragged about my "gigantic
32" TV", or where I own a pool stick. I wouldn't spend 10 dollars on a
bottle of beer and I haven't bragged about Windows Vista, as a matter of
fact, I think it sucks.
