My Dell P2310H monitor has a vertical Blue line and a white horizontal line displaying on the monitor.

Fixing this old of a TV would be a waste of money as unless you have the testing gear and expertise you would be guessing. Just buy new and be happy. You could also join a book club and give up watching TV altogether. LOL

Please check your RAM

This the problem related with LCD. Horizontal and vertical line occur, the cause of LCD data strip disconnected. If you are able to open the LCD bezel and back cover then look display data strip that is connect with LCD. if you need more then hit me mail,I'll be online on fixya.

Tryconnecting an external monitor to the laptop. You may have to select the videooutput to display on the external monitor by holding down the blue key and pressing the blue CRT/LCD (located on one of the keys, likeF8,F9, etc..). If the problem occurs on the external monitor with the batteryor AC power, then you have a problem with either the video card or motherboardin the laptop. If the problem does not happen using the external monitor thenyou laptop's LCD display is going bad.

Hello, It sounds like you have a bad display screen. Here is the replacement.

Dell had a problem with horizontal lines in some of their monitors a little while back. I would try contacting Dell Tech Support to see if your monitor is one of the one effected. I think they were replacing the monitors that had the problem, but I'm not completely sure.

problem in vertical section.

1. Solder the vertical ic

2. vertical ic supply capacitor problen.

Remove dry solder at Vertical IC if problem not solves replace VERTICAL IC and pf104
