Question about HP ScanJet 5300C Flatbed Scanner

1 Answer

Hi there, anybody now where I can obtain a service manual for my

CCFL Lamp needs replacing as it is broken. I have tried HP technical, West coast parts. Chiltern ip, and others but they all say that it is not replaceable even though it plugs into the driver board. They advise buying a new scanner. The scanner itself is about 6yrs old but hardly been used. The manual would help me with the specifications of the lamp so I can replace from a third party source. Any help would be appreciated.

Need replacement LCD Display Screen for my HP Pavilion dv9730us 17" Notebook PC Laptop. Where can I get one for a low price?


If the LCD screen is not physically broken ie a cracked screen then it could have a faulty inverter or a faulty CCFL lamp which will give you a black screen. The inverter and CCFL lamp is a lot cheaper to replace than a complete new LCD screen.

My moniter is so dark I can't see anything


You may have a faulty inverter or defective CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Screen fliks change calor to pink if i move the screen or shake it it came back


Sounds like the cables between the display and the mainboard inside the laptop are broken and would need to be replaced. Those cables can be hard to locate, you may want to take the laptop to a repairer who can obtain the parts for it, or contact asus if you are still in warranty.

if this is a desktop computer then just replace the cable between the display and the computer.
