majithia23 Posted November 15, 2010 Share Posted November 15, 2010 howdy guys ....:hi:well ,,been away from nsane for some time now ,when this strange and rather irritating thing started troubling me and so, thought of asking the people here ...for the last few days the laptops screen is behaving weird ....it starts to flicker , just suddenly ,,,sometimes slowly ( when its still readable from the screen )but some times like crazily . the whole screen is messed up with horizontal criss cross lines , all mixing into each other ..... and thus no readability ...during flickering ,,now two things happen ....sometimes it gets back to its normal state , as if nothing happened , by its own ...and some times it just gets stuck , that is keeps flickering and flickering , and then i have to force shut down by holding the power button ...two things i have noticed ...when the screen background is white in color , it flickers less .and also , while flickering , if i switch over to a window with a white background ( like google home page ),, the on going flickering reduces and some times even stops ..now i have updated the drivers , BIOS , and any other things , but to no avail ..on connecting the laptop to an external monitor , two things happen ...--- when the laptop screen is fine , the external display is also displayed ok ..-- but as soon as the flickering starts , the external display goes all blank ... , no display ....this is the case ...now wat to do ...???p.s. / edit ---- please check the last post for the solution ....

bwop Posted November 15, 2010 Share Posted November 15, 2010 Do you clean out the fan(s) regularly? Do you ever use the laptop on your lap, in the bed, etc?Sounds like your MB might have overheated, especially if it's an HP. Link to comment Share on other sites More sharing options...

Do you ever use the laptop on your lap, in the bed, etc?Sounds like your MB might have overheated, especially if it's an HP.damn .... !thats right ....it is an HP ....:mellow: .......2 members making an absolutely correct guess ...,, phewww..so is HP so notorious for bad quality ...??mine is HP dv5 1201 with AMD Turion ..and by these symptoms it means the MB has been baked / f@@@d up ??is it so ?from what i had read and knew i had an opinion that HP were the best , so went for it , ignoring others ..but this just sounds , i made a mistake ,as this one is around just 1.5 years old ...???:huh:i havent contacted the customer help line as of yet ..coz i know very well from my past experience , they r just a bunch of morons ....so , what to do ????

majithia23 Posted November 15, 2010 Author Share Posted November 15, 2010 http://www.ehow.com/...d-inverter.htmlhttp://en.wikipedia.org/wiki/Backlight thanks for the links man ...hmmmm... interesting to know about the LCD inverter thing ...so if the inverter is dying out , the laptops screen would flicker ...what happens to the screen during the malfunction is , that there is flickering , at a very fast rate .. multiple colored horizontal lines , moving up n down into each other at a very fast rate ..would this also be categorized as flickering ?or is it smething else ? ( like attributable to some other LCD component or the MB ?? )and also , wen connected to the external display , on flickering , the external display just goes blank ...this relation ??

majithia23 Posted November 15, 2010 Author Share Posted November 15, 2010 in this case on board graphics chip/card "kaput!" :pope:ur reply just ascertains my fears ......:doh:was thinking the same ....as mine has an on board ATI chip ....Check your 'Screen refresh rate' and ensure your display driver is updated. BTW, external appliances like wireless transmitters, cellphones, mixers and even fans are known to cause flicker.yes i did check for all the driver updates and stuff ..but nothing ...so if the on board graphic chip is busted ,what is the solution ?a new mobo or the chip could be replaced as a stand alone component ?

bwop Posted November 15, 2010 Share Posted November 15, 2010 We repair this problem on HP laptops all the time. You would need to reflow the board, remove any and all thermal pads, use the correct thermal paste and put in a shim where needed.This usually works, unless the GPU itself is fried.If you are handy, you can probably find guides or videos on how to do this yourself. Otherwise, you'll need someone to do it for you, or have the entire motherboard replaced. We typically charge $75 for the fix, while a new motherboard would be 2-3 times the price.

irefay Posted November 16, 2010 Share Posted November 16, 2010 I would reccomend [careful] disassembly. Get rid of all dirt and dust, and make sure the connections are good. Link to comment Share on other sites More sharing options...
LeetPirate Posted November 16, 2010 Share Posted November 16, 2010 Clean out the heatsinks and fans and replace the thermal paste with NON electrically conductive thermal paste. My personal bests are Arctic Cooling MX-2 or MX-3. Reason is that most of those chips on laptops are without the metal casing and thermal paste can easily leak onto electrical components creating short circuits.Also HP are well known for manufacturing laptops that can also work as furnaces or space heaters in winter. You can fry your legs or burn your house down using an hp laptop.I can only confirm what others have said about your problem, it does sound to me like a video card problem. If it is the inverter you can listen closely to either the top or bottom of the screen for buzzing noises, that is usually the main indicator that the inverter is dying.

( ... though it would be hard to find one ... )i mean what are the chances i would mess up some thing else if i do it on my own ... chances of failure ?@Leet yes u r probably right ...there s no humming i can hear .has to b the graphic chip , on mobo .@bwopu say ..-- try pinching with light force various areas of the case (not the screen!) to see if that helps. if it does, its a safe bet that you do need to reflow the board.meaning u say , to pinch the borders of the screen or some thing else ??

( coz, as i mentioned it earlier also , that the flicker is variable in its occurrence . some times it keeps flickering and sometimes reverts back to its normal state .... )how i wish i could get it checked from u ..!( couldnt find any one good enough and experienced who can check for this error.. )well lets see ...

HX1 Posted November 17, 2010 Share Posted November 17, 2010 Does the screen go crazy when you swivel it.. possibly even go completely black or frozen? Can you tap it and cause a problem? I have seen one HP that had this problem.. I sneezed.. and the screen went nuts.. Nobody could figure out what exactly was wrong.. I was able to finish the maintenance.. but the guy had it fixed twice.. before it went sailing at 70+ MPH out the window of a Big Rig..( Would have hated to have been standing on the side of the road that day.. )EDIT: IF it were me I would start and go front to back, concerning video.. and if it did not fix.. it would be in the recycle bin..
