20 Most Recent Dell UltraSharp E153FPb 15" LCD Flat Panel Monitor Questions & Answers


It sounds as if the backlights are failing. It is probably cheaper to replace the monitor than anything.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

It may have blown fuse in the inverter circuits, so check the fuse and the transistors, solder joints, etc.

It will not be really worth it to have it repaired by a shop.

Yes you can, it's easily fixed, and if you do it yourself it could cost less than £5. Thats if you don't need to buy the tools as well, but if you do then it's a good investment because blown caps are the cause for quite a lot of faults in electronic equipment.

I highly recommend reading the links at the bottom, it'll give a you a better insight into the problem and solution. Make sure you go for a good make of capacitor, or you'll be doing it again at some point.

p { margin-bottom: 0.21cm; } p { margin-bottom: 0.21cm; }

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 remove/replace them yourself if you're handy with electronics, or know someone who is. All you need is a soldering iron and a screwdriver. 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:
drunknmonkey_4.jpg
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.

Tools needed
----------------- p { margin-bottom: 0.21cm; }

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. - will be helpful but not really essential.






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.

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.

Try the following steps:
  1. On the monitor, press Menu, and select Factory Reset.
  2. If the monitor has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.
  3. Connect the monitor to another computer. If the line appears when the monitor is connected to the second computer, the monitor might be damaged or defective.Otherwise, the video card and driver is causing the problem from the computer.let me know if this resolves ur issue.. if not then we need some other steps.. regards,guru

It can be a sign of the LCD Controller (T-CON) board (part of the LCDpanel) is going bad or just loose or dirty connections. You will need to open it up and inspect the inside.
Look at some pictures here to see how involve it is to repair the monitors.

I ahve to assume that your new monitor has a DVI connection that looks like this...
ddcfd5a.jpg Your Optiplex probably has a VGA connection that look like this...

You'll need a VGA to DVI adapter (available at electronics stores or online everywhere.

Or, to take advantage of the higher quality resolution of your new monitor, you might consider buying and installing a new graphics card with a VGA & DVI adapter so you can plug it in directly and get higher res.

Sounds asif the Xenon tubes that backlight the LCD are losing power. Probable cause, a power invertor or PSU fault.
It can be repaired by a hardware specialist, but best written off.
The cost of repair will be better spent on a new monitor.

Dell UltraSharp... | Answered on Mar 19, 2009


Those models are made by BenQ. Their notariety is bad solder connections that cause the drive transistors to overheat. Sometimes it just blows fuse pf751(2 amp); other times it will damage a transistor or two (2sc5707 or 5706 x 4).
Be sure to resolder the output transformer leads.

Hi,
Disconnect the monitor , from the computer, switch the monitor on , if you have some kind of Dell self test box running on the screen. The monitor is OK . The problem can be with the video card or resolution settings.

Also, try connectin the old monitor you had hooked up with the system to check ,if you see anything

Thanks

try another monitor, that way you know what is the porblem, the pc or the monitor.the monitor is not repairable.

The orange light means that the moitor is not seeing any signal. Make sure that the cable is in the correct position on the PC. If that is correct, try it on another PC to determine whether or not the monitor was damaged internally during moving or the PC is not sending out a video signal.
