Pavilion dv6880se - Weird HDMI problem!

Hi All!

I have a dv6880se for about a year, excellent notebook, but Im experiencing the following problem:

First the specs:

O.S.: Windows 7 Ultimate
Nvidia drivers: 185.20 WHQL (already tried a lot of versions)
TV model: LCD Samsung 32 pol - ln32a550
GeForce 8400M GS
Working HDMI cable
HDMI ports tried: All of them, even renaming the AV port on TV settings to PC

- dv6880se detect TV correctly, but my TV keeps showing "No Signal", greying out the correct AV input (tried all the AV inputs), no matter what I do, pressing fn+f4, booting notebook with HDMI cable plugued, etc..

- If I plug my wifes Dell notebook with the same cable and TV everything works fine, AV input turn white and a very sharp image is displayed, as it should;

The weird thing:

- Since Ive "booted" the TV with the Dell notebook and it got signal, if I switch the cable to dv6880se the HDMI works fine, but if TV is turned off and on again, channel or current AV is changed the "No Signal" TV message is back...

Well, it dont seems to be a hardware fault in any component (dv6880se, TV, HDMI cable).

Anyone has seen this problem? Any dv6880se with this issue? Any tips on working driver version?

Any help is appreciated!

P.S.: Sorry about the poor english!

Many thanks!

I think the notebook isn't sending the right power on signal to the TV, so the TV gets confused. Try Dox's drivers here: http://forums.laptopvideo2go.com/to...-85/page__s__1057e3eb89f8f2c5e99e9da57beab56f (remember to UNINSTALL yours first). They are the best drivers i could find for the 8400M, and have quite a number of tweaks applied so they run games with great performance, maybe they'll fix your HDMI problem as well.
