For a LVDS panel, you'll have to get a VGA->LVDS converter.. which will cost more than a brand new 15" LCD monitor.

my 5 year old laptop has died and I was considering putting the beautiful LCD to use, but I have no idea where to start. I have much experience with electronics but I can't seem to find the pinout for my model. I've emailed sony about it, but am doubtful at the moment. the model number is as follows; A8045754A thanks for any information anyone can provide. p.s. it's a samsung display, their site is less than helpful, and I've not recieved a reply from them for quite some months. |

Sony VAIO PCG-F20 and PCG-XG9 LCD .... A8045754A 13.3 A-8045-754-A .... Samsung part number: LT133X7-124 As far as I can make out, it's a 3.3 volt, LVDS panel. I have a good collection of LCD pinouts and datasheets, but I don't have this one. Maybe the above info will help you find it. Unfortunately, LCD manufacturers who sell to other manufacturers rarely like to give out specs - they are generally considered confidential. Try looking at these two - they are not for your model, but often they use the same pinouts. If they look similar, try tracing the power and ground connections on the LCD or laptop board to see if they match. If so, its a fair bet... http://www.axiomtek.com.tw/Download/Manual/PK898B.pdf http://www.axiomtek.com.tw/Download/Manual/PK898G.pdf Maybe try to identify the video controller on the laptop board, get its datasheet (probably easier than the LCD one) and trace out the connections? There aren't that many for an LVDS panel. That's what I would do, anyway. I've done it on a few panels with ultimate success. If you do work it out, please post the info so we can share it. Best of luck, FoxyRick. |

Not if you connect it to a suitable LVDS-enabled board, like many of the small form factor boards out now. Makes a *very* nice embedded system. FoxyRick. |

The items you requested are listed below. You may place your order using the link below or call 1-800-488-7669. Shipping charges and local taxes will be added to your order at checkout. Sony Direct Accessories & Parts Center web site - http://www.sony.com/accessories Detailed specs on LCD are not available.

No, you need a controller which will output the "correct" signals with correct timing to the panel. |

I don't know the pinout nor the type of controller I need for the panel. my trial-and-error approach was going to be a blind attempt at determining this. |

I think I found the controller. THine TI000704 THC63LVDM63A ... alas I can't seem to find a pinout for it as of yet. Also, upon further inspection, there are 18 wires [ on a 20-pin header ]; Black Grey White Orange Yellow Red - [ no/use ] BW--GOYGOYGOYGOYBRBR [ printed on a piece of tape with, what looks like, Japanese lettering, that holds the wires together ] 1-906-645-21 and there's a chip under a flaxable PCB that's taped pretty firmly to the back of the LCD - I've not succeeded in pulling it back to read what's on the chip, but what I do know is that it's square with hookups on all sides. ... And now for some more numbers printed on the back of the panel; F8575E-X(47L7106) HY6802-01 FDK24786(04) //edit "Library for National Semiconductor DS90CF363 LVDS encoder for flat panel display. Also suitable for pin-compatible THiNE THC63LVDM63A. " quote from http://www.cadsoft.de/cgi-bin/download. ... /libraries |
