Question about HP Pavilion M70 17" CRT Monitor

1 Answer

White Sharp Horizontal Streak on Center Screen

Started noticing the problem in Subject. Opened the Monitor Cover & found, if I lift up and hold the Circuit Board corner near the Screen Focus / Brightness Adj. control, the display is back to normal. I suspect a Dry solder / Broken Solder contact. Do not exactly know which point to re-solder. If anyone know which point(s) to re-solder it would be great. Otherwise I need to re-solder all the contacts in that corner/area of the Circuit board.

    I fixed this Problem. The following question
    "QUESTION NO. P61203-10: HP
    D5259A monitor Chassis C-711 has a horizontal line across the
    screen. Resoldered cracked solder joints at I602 (vertical IC),
    still horizontal line. R618 is fried, what is its?"
    This question perfectly matched my problem & located the IC602 on the board and found a crack in the solder on pin2 !! :-)

Hello RepairKid,

Although it's difficult to pinpoint which solder point(s) are the cause of a problem of this nature, the use of a magnifying glass will help you determine which solder point(s) look "irregular" compared to the other ones. Look for cracks or pits across the solder point and re-solder once found. Sometimes a hairline of solder is shorting out two points and again is might not be possible possible to see without magnification. If you don't notice any irregular solder points, a component could be causing the problem (like a very dirty/oxidized potentiometer or a cracked discrete / SMD). Let me know if this helps.

Vertical strip of flashing horizontal lines on Acer Aspire 7551G screen


More than likely it's the lcd screen and will have to be replaced. I could be the video card, but most likely the lcd screen especially when you can put pressure on the screen and cause changes. To isolate the problem try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok, then the problem is with your lcd screen and the video card is ok. If the Borrowed monitor displays the same as your lcd screen then the problem is with your video card inside the computer.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Once you narrow it down to the lcd screen as being the problem you might try taking the lcd screen apart to reseat the lcd cable on the back at the top of the lcd. Just unplug it and plug it back into the connector. You can also try doing the same where the lcd cable plugs into the motherboard. Just pull it out and put it back.

Then Pull Toward You the Bottom Maybe Anchored So Lift Up. 4.Once Speaker Cover Removed, May Have Screws Just Below Center Plastic Cover Remove Them, Now Remove Center Cover Between Speakers -NOTE" Do Not Touch, Move Any Color Convergence KNOBS" - Lift Front Screen UP - Towards Roof - It Has 3 Flex Grab Anchors On Top And 2 Pins One On Each Side Of TV Frame. - NOTE" Lay Screen On Floor It Is Plexi Glass So It Will Brake If Bent Or Drop Hammer On. NOTE"- May Have To Remove plastic Cover Frame positioned Around Front Screen And Then Remove Screws. 5. I Use Windex Glass Cleaner And Either Cotton Balls Or White Tube Sock On Color Gun Lens Covers And Clean Mirror Like The One In Bath Room. 6. Take White Sheet Or Bead Spread And Anchor On top Of TV With Weights, Stretch Around Each Side Of TV Use Chairs To Anchor On Each Side Of TV. Place Dust Cover Or Heavy Card Board Where Plexi Glass Was Positioned. 7. Turn On TV - go To Rear and Now You Can Adjust Colors Brightness And Low Light - High Light - Horizontal - Ect....While Looking at Picture. 8.

If your LCD monitor has damage it could be in three forrmats:

1) Damage LCD ribbon. The screen will power up bright white and you will see random strings of color in diaganol or horizontal streaking slowly across your screen.

2) Damaged Liquid Crystal Container. The thin glass/plastic may have ruptured due to an impact on the screen. You will see sharp jagged lines and maybe a partial post screen, but where the sharp "jaggies" are, are now permantly broken

3) Nothing on screen. This indicates that your internal CCFL (oh I love LED technology) tubes have now lived their life and will not ignite. To test this method, hold a very bright light to the screen and see if you can see any logos (Compaq/HP/Win Xp loading screen...etc)

If you can see something, your screen is fine, but there is no light behind it for you to see.

Hope this helps.

White intermittant horizontal lines


Sure it can be fixed, I think some components on the main board needs resolder on their soldered joints. Try this first before thinkig of getting a new one.

Proview PL926Wbi LCD Monitor White Screen


I found in the refuse, a Gateway FPD 1520, 15" LCD monitor that started off losing the screen half-way, losing sync, etc. The "mechanical agitation" method was applied and remedied the problem. Awhile ago, it went to a white screen (or, as it was back in the day- a clean raster). I opened it up and found that the ribbon cable on the left was loose. I applied a series of layers of adhesive-backed foam (the kind you stop drafts in your home with) until it was greater than the height of the metal enclosure to put pressure on the unbehaving connector. It does seem a bit loose and this will keep it snug. Maybe hot glue or other adhesive if it wiggles loose again. Seems to have solved the problem at the moment.
