Problems with Pioneer 5090H after ISF calibration

post #1 of 7
Thread Starter 
I finally had my Pioneer LX5090H ISF calibrated yesterday but now I am experiencing some weird flashing. I have always been running drive mode 1 for some reason but after calibration I am running drive mode 2. According to most experts and the guy who calibrated my TV drive mode 2 is way to go.
The problem is that with mode 2 I experience randomly flashing in the background of the picture when watching SD or HD through my DVB-C settop box. It's especially visible on "one" colored backgrounds, like when I watch a soccer match(in the grass). As soon as I switch to drive mode 1 it completely disappears. Also when I switch AV mode by pressing the "Tools" button and then right or left to choose I notice that the TV flashes a little bit just once. This also only occurs with drive mode 2. I don't notice anything when watching bluray or gaming on my ps3. And as far as I understood the drive mode settings only works for 50Hz broadcasts.
Any suggestions about what could be causing this? I can se that I am running with a very old firmware. Maybe I should try upgrading this. Can somebody please confirm that I won't loose my ISF settings by doing this.

I assume you paid a fair amount of money to your calibrator and would go back to him with the questions and see what he can do for you.

Yes already spoke to the calibrator. He said that my TV could be broken but first he suggests that I upgrade the firmware. Oherwise he might drop by again next week to check the settings and so on. I just wanted a seccond opinion from all the experts in this forum ;-) And yes I paid a large amount of money for this calibration(450$)

Try www.avforums.com -- they will be know more about European sets. This is a pretty North American-centric forum, so the whole "drive mode" thing won't be familiar to us.

Hi MortenN, if you're able to read german language, than you can inform here.
The Flashing is a known problem with drive mode 2 on some PDP-LX5090H.
The problem is known by pioneer and described as "Intermittant flicker in the picture when in 100Hz mode combined with either STANDARD,USER or ISF AV modes."

You can only fix it, with a firmware update, which must be imported of a Pioneer technician via the RS-232-interface.

The flashing only occurs when Drive Mode 2 is combined with either STANDARD,USER or ISF AV modes.
So the reason why it has not occurred before calibration, is because you used Drive Mode 1.

In germany the update is named 04Y.

Hi M5ster. This is indeed very good information. I do read german pretty well. I will contact Pioneer about this. Thank you very much ;-)
