Adapting a samsung panel to Vestel 17MB211

[saronno]

Hi, I have a telefunken tv with a broken panel (VES315WNDA-2d-n12). The tv has a 17mb211 board.
Since I had a samsung with a good panel (df320agh-r1) I try to adapt this to the telefunken.

Pinout was almost the same (the only thing I have to move the connect on the 17mb211 according to the image below ... from double lvds to wxga fcc).



Panel is working bad badly. Color is wrong ... image was flip (I was able to correct this playing with ptf.ptf file ... b8HFlip = 1 b8VFlip = 1 to be precise ).

Does any of you have any experience with vestel board and ptf.ptf file parameters?

I attach also the ptf.ptf file ..

I didn't spot any difference but flip parameters. Am I right?

to me, looking at the image, it seems as if there aer not the full range of colors, like when you setting pc video card to 8 bit or 16.

T-CON intgertated at Panel ?? if yes can you show here the T-CON chip so i can see it to check yours parameter

actually this problem looks like a lvds socket problem. I tried the panel software on the Samsung panel and it worked without any problems.

VES315WNDA-2d-n12 = CN16
Samsung HD = CN15

CN14 should not be used this chassis

Tomorrow I will open it again to make some photos.

Probably you are right. I move the connector a couple of week ago so I am not sure ... anyway right now it's at cn15

You mean I should recheck cable and connectors?

If so, I guess it could be some problem with the tx pins

clock is improbable since I have a picture .... but one of the tx line could impair some specific bit in the frame if it's not working or malfunctioning.

I didn't find the datasheet for the samsung panel I am trying to adapt to the vestel, but I find this one below I suspect have the same pinout


https://datasheetspdf.com/pdf-file/9...g/LTA320AN01/1

This is a picture of the connector of my panel


So, as I said, it has the same pinout of the board (CN15) but it was mirrored.

We need picture of chassis.

Ok, I solved. It was the connector.
First thing I asked to myselft "why everything is reddish" ... so in the samsung pdf
i posted above I checked "what if red is stuck" ... and so tx0 has to be 1 all the time .... and so I checked with my multimeter and the two line were shorted together (a little bridge under the connector not visible from above). Anyway I changed the connector completely (the old one was in bad condition after a couple of soldering/desoldering) and now everything if fine.

Anyway, Thanks for the help.

Just to sum it up if everybody else want to try to adapt a samsung panel to this
vestel board: yes, it's possibile but be careful with the pinout since it's mirrored.
