You most likely have a problem with the voltage protection circuitry, the screen starts up, the crowbar is somehow activated, and it shuts it down, You need a service manual. Below, below that is a user manual, they have invaluable information, The service manual has troubleshooting and repair info found nowhere else.

Compaq presario 700. The screen, after running for about 5-10 min, gets white lines horiz. and vert. and then goes all white. I have to turn it off for a while and it goes away. (for 5-10 min)


The monitor heat sheild is probably damaged. If you don't have a warranty then you will probably have to replace the lcd panel on the computer.

Hook an external monitor up to it and verify that that screen doesn't scramble. if it does not and the lcd does then the lcd panel is damaged. if both do then you have a motherboard problem with the graphics card. either overheating or damaged. There is also a possibility of memory issues but the first 2 things i mentioned usually over this problem

Horizontal Line through middle of TV screen


This is usually a bad elect capasitor or a bad solder connection on the vertical IC, The capasitors will be close to the vert chip..Sometimes you can clear problem with a light tap on the TV, if so then suspect bad solder.

Vert deflection problem


You are correct about having a dry or leaky capacitor that is causing those lines to show on the top of the screen.
Check the caps with low capacitance like 1uf, 10uf, 47uf, etc.
No quicker fix for this one until you change the capacitors.
Hope this helps.
