Radeon 9600SE DVI Problem after MDP-130 Installation

[TheMile]

My HTPC had been working properly for a few months (literally, I didn't turn it off in about three months). I've got a Radeon 9600 hooked up via a DVI->HDMI cable to a Sony KV-30HS420, and with Powerstrip's custom timings, everything was going fine.

I purchased a MIT MDP-130 with DVI daughter card and installed it recently. The MDP-130 card seems to work perfectly when I switch it to HD mode, but for whatever reason, the DVI port on my Radeon isn't detecting my TV at all now.

I tested each part independently, that is, I verified that both the Radeon's ports work with my extra monitor, and that the HDMI cable and TV work when I use my MDP-130 in HD mode.

Baffled, I pulled out every card but the Radeon and reinstalled Windows XP SP2 with Catalyst 5.4 drivers, but now the video card won't output anything at all to my TV. It used to display the POSTing and bootup process on my TV, but now it won't even do that at all.

If anyone has any help they can give me, I'd appreciate it. Thanks for your time.

Sony KV-30FS420

Just a single bump for the evening crowd.

So your TV has 2 HDMI inputs or 1?
If one then is what you are saying is that after using the DVi /HDMI cable with the MDP130 card that when you move it back to the Radeon card even if you shutdown the TV and the PC and start both back up again?
Make sure you don't make any DVI cable changes with the units turned on because some people have reported that that has blown the DVI transmitter or receiver chip in one of their units.

My TV has only 1 HDMI input. And your description is more or less correct. I've shutdown the computer entirely, removed the MDP-130, and hooked the TV up directly to the video card, but that doesn't work any more. It used to.

I don't think I've blown out any of the DVI ports, because I've confirmed that both the TV HDMI port and the video card DVI ports work independently from each other. Well, I've attached a DVI-VGA adapter to the back of my card's DVI port and verified that my spare monitor still works with it via that arrangement.

Is it possible I've blown part of the DVI port, even though the DVI->VGA->monitor arrangement works?

Thanks for the help.

Absolutly since the DVI-I connector contains both the DVI signals and the analog VGA signals and your adapter is just picking off the VGA signals.

I see. I'll go find another DVI monitor and see if that works. If not, it looks like I blew my card's DVI port, I guess. Thank you for the help.
