Hi, I recently purchased a defect HM8118 on eBay. This unit has several issues, one of which is that only half of the display is working,as you can see from the attached pictures. I managed to update the firmware from V1.47 to V1.57, but of course this did not fix the LCD problem. The LCD is a COG-LCM138-06 with serial number: 110111408422, and I presume that the one of the controllers on the LCD is faulty, and thus does not drive part of the LCD anymore. Does anybody have a spare working display for sale, or else can me provide a datasheet, because I searched the internet, and cannot find any information about the LCD; not even who manufactured it. I also could not find a service manual for the HM8118. If somebody has this a copy would be greatly appreciated. Here is all the info what is written on the LCD, and also on the separate backlight unit. (see also the pictures) FPC-LCM138-01, 2004.05.11 3810 SHON58 VL COG-LCM138-06 WU621A-01 LBL-LCM138-01A 210/11/06 Thanks |

have a look into the comments of Maybe Michel.Waleczek (at) gmail.com can help you out with a manual... |

Good luck, sourcing this kind of display is a nightmare. Of course you could kindly ask Rhode & Schwartz for some information or spares. If you're on your own in the end, it can help searching to know the display resolution, number of pins on FPC and bus data format. |
| Hamelec:
cant believe that it is a failure of the display themselfes, more of the flexboard/connector or driver unit |
| coromonadalix:
as for the problem, could be hw failure of the lcd matrix glass or on the flex lcd assembly or even the lcd controller ??? yes ask the company under an non disclosure agrrement if you can order the SV Manual ??? or get that part ? Unless it's a customized one ??? because of the 2x pcb traces groups on each side, i never see theses in lcd's ?? |
