    AS15-G Chip

    I am replacing another AS15 gamma chip and one of the pads (pin #9) came off on removal of the old chip. The best I can tell scraping the board around where the pad was, there is no traces connected to it. The 2 pads adjacent do have traces. The pin is labeled as "Go" on the datasheet. Does anyone know if I'll be OK? Thanks!

      Re: AS15-G Chip

      "Go" is probably channel G output, if there is nothing connected to "Gi" (channel G input) you should be OK.

          Great it doesn't look like anything comes to "Gi" either, thanks Tom.

              That fixed it. TV had bad color/contrast symptom.

                  Interesting, did not know 40" panels were affected too.

                      I've had this problem mostly in 40" models, and some 37". I love when I find them.

                              I think almost all I have done have been AUO panels.

                                  Oh I had the same model sony with the same brightness contrast problem. Turned out to be the AS15 chip, but for some reason it was much harder to remove than the other tcons ive done. Ended up ripping off 10 traces and had to do a crazy wiring job for it...

                                      Just got one of these panels with T-con 55.40T02.C06 however I can not find the chip for sale. Does anyone know where I could find it. Shopjimmy is out, even though there amazon listing says they have some.
                                      Not really sure where to look.
                                      Any help would be appreciated.
                                      Thanks

                                              I've got mine from AliExpress, and to echo what Alastair says they are sensitive to heat.

This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

                                                          - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
                                                          - gave the computer to his son a couple years later
                                                          - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
                                                          - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)

                                                          I need to add w25q256jveq chip but I do not know what data should I type.

                                                          I'm using the ezp chip dabase editor posted from here https://www.badcaps.net/forum/troubl...ro-programmers

                                                          Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.
