COMPAQ w185q LCD Monitor Blank Screen Repaired
Received one LCD Monitor to my workshop, Compaq Model: w185q described fault symptom is monitor shows “Blank white Screen” when power “ON.”
After taking this monitor to put on my workbench for testing, after turning the Power ON of the Monitor there is a blank white screen and no “OSD” on the screen.
This type of Blank white screen without “OSD” indicates problem with Logic Board LVDS section. Hence opened the monitor for further testing and started visual inspection.
I have removed the Whole Cable and found whole cable in horrible condition.
Further I have checked LVDS Socket and found Bad solder on some of the pins on socket.
Now this is to time for order a new LVDS Cable. Till the Cable is arranged I have to refresh the solder on the LVDS Socket.
Till the time I have checked the Logic PCB everything seems to be ok as no physical damage found.
Now received New LVDS Cable
So attached new cable and powered the monitor for result. Yes Monitor is back to the life but here I found one vertical Pink line on left side of the screen corner.
So I called up the customer and described the work progress to him. And also I discussed about suspect the panel itself bad for the vertical line that time he told me that he is using the monitor in this condition since last 2 Years & He was on hurry to take back the monitor.
So I have returned the Monitor to him in this condition.
