LVDS Output Of Peaks LD4 IC-8000 (2ws0250)

[Chaks]

Can someone provide (help) me with the information on the format of LVDS I/F output from Peaks LD4 IC-8000 (IC 2ws0250). This IC is used in the Panasonic Plasma TV as the main Audio/Video Processor.
There are 24 pins coming out from this IC designated as LVDS Out.

Panasonic plasma TH-P42XT50 LVDS Output Of Peaks LD4 IC-8000 (2ws0250)

Can somebody help me with a link to IC-8000 data sheet. Panasonic part number Mn2ws0250.

Can someone help me with a link to IC-9300 (P/N T6VU4xBG-0001) datasheet.
I could not find it on the internet.

That chip will be custom Panasonic ASIC I expect, so you'll have little chance of getting datasheet for it.

Best you'll get is Service-manual for the set itself.

IF its supposed to be outputting LVDS you can scope it while changing menu functions to see effects on digital waveforms....

---BTW--You dont say--whats actually Wrong with the set.....

Thanks a lot for your replies.
Here is the link to the lvds pcb traces on the A-Board.

I am looking at the possibility of feeding the lvds output of IC-8000 to an external LED panel of same resolution and specs. The working A-Board (+ powersupply) is removed from a broken TV (my own tv, the sn board and the display are dead but the powersupply and a-board are confirmed/showed working by panasonic service guy).
I am looking for the lvds specs because if I can find a LVDS panel that is compatible with the LVDS output of this tv then I would be at some comfort that I could reuse some of the parts ... which otherwise is a $900 reduced to JUNK/SCRAP.

if I build/buy a LVDS receiver with a TIA/EIA-644 circuit ... can i further extend that to support a more standard format ... like a RBG or a DVI standard?
Something like this:

I would be surprised if you could find a panel compatible with the format. Panasonic does a lot of image processing on their A boards, one of the things they no doubt do is use a custom colour and frame format to make image processing easier on the D board. (A plasma panel controller has to separate the 60Hz image into 10 subfields, each subfield representing a weighted intensity.) This requires a lot of processing to do.

Re: LVDS Output Of Peaks LD4 IC-8000 (2ws0250)

During the last week when I was trying to find information on the ic-8000 used in the a-board ... I have come across a panasonic article that said the new a/v processor does all the processing and outputs a standard lvds interface supporting a 1024 x 768 resolution. This is fed to a plasma ai or a led processor that finally displays it on the screen. Initially this was a 10bit lvds signal output but i am not sure what signal type they are using in this th-p42xt50 tv.

I have an old lcd panel with the same resolution of 1024 x 768 with a lvds input. I want to do some testing with it first. I have the driver ( power circuit) for it so I am trying some way to feed the lvds signal to it.

Thanks a lot for the replies ... It keeps me going to find all the possibilities if any.

Still searching .... anybody out there who can throw some light?

Re: LVDS Output Of Peaks LD4 IC-8000 (2ws0250)

On the TH-P42XT50, is the LVDS not contained within the main board and the only signals are those for the panel drivers and SS(P) / SN board?

Re: LVDS Output Of Peaks LD4 IC-8000 (2ws0250)

Yes tom66, the main board (A board) contains the LVDS pcb traces that go from Media Processor (IC8000) to Plasma AI processor (see image in the link below). There are pin points along the 24 LVDS lines/traces on the PCB ... I can solder individual wires to these pin points and connect the other end to a LVDS connector and use this to feed an LCD panel. The possibility that this would work depends on the LVDS signal the IC8000 sends to AI processor. I have tried to find this information but nowhere it is mentioned or found.
