Laptop monitor problem.
Hi,

I am currently in Sweden and on the trip from the airport the bag carrying my laptop was dropped. Ever since the screen has not worked properly. When the screen is held in a certain position it works fine and normal, but I can't very well hold it in place forever. It works fine on an external monitor as well. When not working there are horizontal bars of the image that don't show up, sometimes the whole screen gets blurred. I've tried reconnecting several wires including the inverter ones. No changes. Wondering if anybody else had some insight to the problem. As I said I am visiting Sweden for a couple of months and don't have access to my normal resources. I don't even know if I can locate a local repair shop. Thanks in advance for any help.

If you are pretty sure that all of the ends of the interface cable(s) are firmly inserted into their mating sockets, the drop may have broken some of the interconnections between PC boards inside the LCD panel or between the PC boards and the panel's display glass. If that is the case, replacing the LCD panel may be your most cost effective repair choice.

Thanks, would the screen occasionally work at certain locations if that were the cause though? It seems like the lcd panel is working perfectly when I give the top of it a slight "twist". It seems to me like there is a definite connection issue, but I don't know where the issue is...

Neither the LCD panel or laptop lid is going to be 100% rigid. Any twisting or bending of the laptop lid would be transferred to the LCD panel and any twisting or bending of the panel would be transferred to its internal electronic assemblies. Some of the interconnections between the internal boards and the glass are fragile. A shock from dropping the laptop could break the solid mechanical interconnections that would become intermittent with temperature and/or flexing of the panel.

Thanks for the help. I verified that it was a problem with the LCD panel by rechecking all of the connections and ordered a replacement panel. You saved me from wasting time on a new inverter as everyone else I've talked to had recommended.
