HP Pavillion dv800 screen jumps but has clear picture

you may have a bad ground, or the ignition switch needs to be replaced.

Check to be sure the ribbon connections are tight. If they are and the previous screen worked perfectly before it was damaged (assuming it was replaced because it was cracked etc) then you may need to return the screen and try another one.

Flickering is a back light issue, jumping around would be caused by the screens reaction to a bad inverter and so would the backlight as well. So flickering backlight and jumping would be a inverter issue causing both problems so I would replace them both.

I faced the same problem with my laptop and the fault was with the power adapter. I noticed that the cursor moved randomally only when the power adapter was plugged in. I got the adapter replaced and it is working fine since then.

check yo RAM,Or VGA

Greetings!

When the battery terminals were replaced, be sure to check that all the wiring was correctly installed. (Pos+ to Pos+ and Neg- to Neg-, etc.)

Sounds like something got missed and the ignition system is not working... be sure to check the main fuses and replace any that are blown.

check the solder around the area of the vertical IC. solder is either cracked or else cold. Cold solder appears as dull. Resolder anything that isnt shiny.

Probably a 'cold or detatched' solder joint on a component on that perticular circuit board you are 'wedging' with a plastic rod.

the best thing 2 do is buy a new one and get guarnteed with it again
if u try 2 fix it it not 50% working


if u got guarnteed then take it back (or phone them to come)

you have lookse connection on the video convergance amp ic
