No Sound!! Hp w2207 Pls Help!! Por favor ayuda!

Where is the IC U11 located? is it on the power supply or the buffer PCBs?
You have to have skills to remove and solder the IC and if it's a surface mount then, you need to have the right soldering equipment and you must be an expert.

In my opinion, I would try to replace the whole board instead.

Best of luck

Dear Fixya Team, I have a problem in my LG flatron F700B 17 inch CRT monitor. My monitor was connected to an external TV card. The adapter of the TV card was defective and my brother plugged in the direct...

The "IC" (Integrated Circuit but often called a "chip") you have been told to be the problem, is a generic diagnosis. There are dozens (or more) of IC's in modern electronic appliances - including your monitor. ICs are what has allowed electronics to become miniaturized as they combine the functions of one or more circuits that may have needed large, bulky, heat producing vacuum tubes to something before that now is the size of a pin head. They look like these:


Drawing of the inside of an I.C. Actual I.C.

ICs come in all sorts of sizes and perform all sorts of different functions. Some are very common and cost significantly less than a dollar, while others are very specialized and cost hundreds or of dollars or more.

Since the power indicator of the monitor is lit, some or all of the power supply circuits are OK. Unfortunately, there are a great deal more circuits inside the monitor - one or more of which have failed.

Your repairer may have not even bothered to diagnose which IC had failed as the prices of monitors have been falling for so long, many people simply replace them with new, thin screen devices instead. If you wish to attempt the repair yourself, you should ask the repairer *which* IC has failed and then obtain it yourself to for replacement. Without the required knowledge and test equipment, knowing which IC to replace will be impossible to determine.

This is only an overview of the problem your monitor has. You will probably find that repairing the monitor is too time consuming and / or parts and other information about it are too costly or difficult to locate - or both. Good luck to you.

Seems like FixYa don't like me posting images in the solution box.
I'll send you a link instead. The image is quite small, but as I don't have the shecmatics myself, I had to look it up...I guess you can download it as a .pdf file though.

There you go!

Hope it helps. Good luck!

I have a model Q7C4 when turned on it immediately turns off again even if not connected to the computer (ie power only)

Most modern monitors will not run if the signal from the computer is not present. If you can borrow another monitor, see if it will work. If ok, the problem is within your monitor. If the new one doesn't work either, then the problem is likely the video circuit in the computer--a bad video card if it's a desktop, but a bad circuit IC if it is a laptop.
