Philips 40PFK4100/12 CI key fail error

Hello everyone.

I am facing a red message above the screen permanently, also the image is greyed and the TV is unusable as is in any sources.

Of course I tried everything basic or a bit advanced, so I updated the firmware to version 2.550 which did not resolve the problem.

Accessing the secret menu by

Home+1999+Return

I have access to 3 interesting parameters regarding this issue
-DRM Warning
-CIPlus Query
-CIPlus update

Obviously I tried to set DRM warning to OFF but this don't sustain, when closing the service menu it always set it back to ON
CIplus update leads to an update error .... I did not expect anything other, though I found a key on some forum ...
CIPlus Query this one is interesting, it shows :

Valid: no
Customer code:
Serial Number:

Then customer code and serial number are blank, how comes !? For me it shows clearly a corruption in the NVram. Perhaps the previous owner bricked the TV set with some junk or modified update or possibly a simple corruption.

Then the next step was to enter in the hotel menu doing

Home+062596 + OK

there is nothing capital, except to erase fault codes, that does not resolve anything obviously.

what do you suggest next, I guess it is now time to burn the chips onboard with a good dump ?

Thanks for your tips.

find CI+ or CI Module and insert it at socket.. then do again what you did before

I don't have any, it is not in use in Belgium, it should not need it anyway. what would it change ?

Have you updated with the three-file firmware EmptyBurn_package 2in1_V2.550?

To save, you don’t need to exit the menu, but pull the plug out of the socket, then the changes will be saved.

Try again in the 13th point Virgin Mode press OK, the TV will think for a bit and reboot with the initial factory settings as from the store

Hello

Thank you both for your replies.

Every updates I could find was in a zip comprising the three files which I copied to the root of the USB stick and installed by the update option of the normal menu.

Yes I forgot to mention I already used "Virgin Mode" in combination with "DRM Warning off" , no success doing that.

Do you have such an update, we tried it "EmptyBurn_package_with_2.330.zip", which contains 11 files?

[yoritomo]

No I did not find yet a such full update.

[lotas]

Sent it to me in a private message.

[yoritomo]

I installed the new update, no change except it has no more option in the secret menu to disable DRM Warning ...
I had an Idea, if the CI key is calculated on the serial number, it might be interesting to grab the Serial number of the donor TV to associate to the dump containing the key, despite to find the calculation algorithm

this is register.. doesn't have to do with Firmware... if the register lost we need to have it back at function Module , this why you have always No Signal

try change region to germany

Diah : the only place the country can be changed is in the channel search, it did not solve anything, anyway the problem is general to every sources. The signal by HDMI or USB file is there, I can see the Image but darkly greyed.
