p { margin-bottom: 0.21cm; }a:link { } Sounds like some bad electrolytic capacitors, if it is then it's easily fixed, but it could be an inverter or backlight problem. I highly recommend reading the links at the bottom, it'll give a you a better insight into the problem and solution, even if it isn't bad caps the link will help.

You have 2 or 3 options:

1. If it's under warranty then you could send it back to be fixed, problem is they will likely use the same rubbish brand of capacitors again, but anything else will void the warranty.

2. Pay a tv repairman or similar to fix it for you. They may still use substandard capacitors, so specify what brand you want them to use, this will probably mean waiting longer and possibly paying a little more. This way you know the job should be done right.

3. You could replace them yourself if you're comfortable with a soldering iron, or know someone who is. The capacitors themselves are quite cheap and easy to replace.

Go for the best ones you can get for the job and try to buy from reputable companies, the links below will help you chose but you can't go wrong with Rubycons. Every capacitor manufacturer has several ranges, each having different properties which make some more suitable than others

Always match the values on the original capacitors. You can actually use slightly different values for the capacitance and voltage (uf and v) but never use ones below what the originals are rated at.

The links below will explain this further.

They should look something like this:

As you should be able to see, the one on the left is bulging. The blue stripe with the arrow tells you that the lead on that side is the negative, the positive lead should also be longer than the negative one(only on a new cap, old ones will have been trimmed).

Tools needed
-----------------
1. Soldering iron. - preferably with a stand with a sponge in.
2. Solder - there's different types so make sure it's suitable for electronics
3. Phillips screwdriver
4. Flat head screwdriver
5. Wirecutters
6. De-soldering wick, or pump. - definitely recommended but not really essential.

If you haven't already got the tools then it's a good investment, as bad caps cause a lot of faults in all kinds of electronics.

Instructions
--------------
1. Unplug monitor and open case.

2. Identify power board, it should have a lot of electrolytic caps on there and obviously should be connected to where the power lead is attached.

3. Identify the bad caps, they should be bulging and/or leaking, although not always. Note down the three values for each cap (eg 220uf, 16v, 105c) and their approximate dimensions, and get new ones, preferably Rubicon or Panasonic, the link below will help you chose some good ones. If in doubt you could remove them and take them to the shop, but you'll have to remember where each one goes and which way round it was (take pics).

4. Very carefully heat up the contact on one side with the soldering iron, and rock the cap the other way, then do the other side, keep doing this until the cap comes out, if you have a de-soldering wick/pump use it to remove the solder and it should just pop out easily.

4. Replace with new cap, making sure that you observe the polarity and make sure it's securely seated and soldered in. Make sure the solder is neat, tidy and doesn't contact anything else. If there's any solder left in the holes then you'll have to heat it up or remove it before you can get the new cap's leads through. Once done properly trim the leads off so they won't cause any problems.

5. Replace casing and test. If it doesn't work then you'll have been a bit messy with the solder, tidy it up and try it again.

Here's a few links to help you:

Hints on soldering.

http://www.kpsec.freeuk.com/solder.htm

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ? hope this helps

That can be bad lamps, or bad caps also, but I suspect the lamps.
When lamp gets old it usualy turn on pink and turn white after warm up, but if it is really bad, it will cause the inverter circuits to go into shut down to protect the circuits since bad lamp can draw excessive current. You can see bad lamp album.

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Ports on the monitor are for receiving the signals from the sources, not for sending signals out to another devices.
Your TV HDMI should be connected directly to the video source output, not through the monitor.

did you try safe mode? restart > press f8 in and after bios > safe mode.

try to make it stop going to sleep there...also make sure its sleep and not shut down...if the computer restarts after u press the power button its not sleep.

Make sure the audio cable supplied with the monitor is connected correctly. Make sure it is connected to the green (speaker out) jack at the back of tower and the same green (audio in) jack on the monitor. Also make sure the volume on both your PC and monitor is turned up and not muted

ladywoman197, 2 things for you to do. 1. disconnect-reconnect vga cable a few times from the DB15 vga port on the pc. If problem (pink hue) persists then try here: http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-blackout-solution/ Your unit may need some new capacitors installed on the power supply printed circuit board. Read fixya profiles of "budmrtn" "12fixlouie" and also visit youtube for video clips of lcd monitor repair. Do the vga cable thing first!!! Could also be vga graphics card inside pc not making good contact with monitor cable. 12fixlouie

I just moved and when I connected everything with my computer speakers do not work. Says that they are not connected and I have no more USB cables dont remember having any connected before from the monitor to the computer.

Check that the cable is fully seated on both the computer and the monitor. Try a new audio cable (3.5 mm male on both sides). If these do not help, check if the computer audio works with other speakers.

I've found that the speakers in a monitor will fail before the monitor does. The price to fix them is such that you're better off getting new speakers.

I hope some of this helps.

Above is your manual.
All things are fixable it simply depends on if you wish to spend the $$ to repair.
In my opinion, after that long, the monitor should be replaced, as even if repaired it would still have old components in it, and we find, that once a unit faults, it will usually fail again inside of a year, according to stats too.
So you would be better putting any money for a repair into a new monitor with a warranty...

Pls check whether your cpu is properly booting because your monitor sleeps out because there is no signal detected coming in from the cpu try to connect your monitor to another cpu so that you can determine the proper operation of the monitor...

Vertical lines are sign of failing T-CON board which is part of the LCD panel, not much you can do. It will get more lines, try it on another PC.

matt5883, Since there are thousands of units that need work done on them, I'll just bet that you will find a video clip at YOUTUBE that will be worth a thousand words!!! Once you get to YOUTUBE do search (query) for "lcd monitor disassembly" and also "lcd monitor repair" You will truly be amazed at what you can find on the web these days!!! 12fixlouie

Hello

Something you can try is to have a look at the frequency of the monitor. Right click on the desktop, propperties and have a look at the settings.

It is usually the wrong frequency which result in a noise.

Hope this can be helpful.

Kind regards
Andrea
