Tip

LCD Monitor Repair (Capacitors)


This tip is a generalized repair based on the inverter board itself and can be considered to be about %75 effective.
Power board repair is pretty much the same as inverter board repair since, unlike LCD Televisions, these 2 components share the same board.

Here is what a typical power/Inverter board looks like.

You will notice, at the top of this power board inverter combo, several cylinder shaped objects. These are called capacitors, and we will be dealing with only these components for this repair procedure, since this is the leading cause of LCD Monitor failures.

You will notice that each capacitor has an X or Y shape grooved into the top.

Ruptured Capacitors

This X or Y is designed to buckle outwards in the event that the capacitor fails, as shown in this photo.
Your capacitor can also swell out of the bottom and separate it from the board. This will most often show as a black rubber like stopper protruding from under the capacitor. If either condition exists, then this repair is for you.

Ok, so now you have the cause, so lets see if this repair applies to you.
Disassembly of your LCD monitor is actually harder than the repair itself.
The easiest method I know of is to first remove all screws from the LCD, remove the stand then use fingers alone, and slide them under the plastic frame at the front of the monitor.

WARNING!

Prying in this area with ANY tool will most likely crack your screen!
So don't use tools here! You can also use a thin flat piece of steel, such as a butter knife along the outer joint of the plastic frame itself, rocking gently between the joints to separate the locking connectors between the frame and the back plate. Remember that each LCD model is different, so proceed with caution.

If you were successful, you should now be seeing a panel with a silver colored metal RF (Radio Frequency) shield covering both your power board and your VGA connection board. You will need to peel the chrome looking tape, (Copper on some models) back and remove this cover.

You will see some wires going from your LCD screen to your power board/inverter. These are usually colored pink/white and black/aqua.
You will need to remove all of these and mark the power board so you will know how to put them back the way they came off.

Next, you will need to remove the data/video cable leading to your LCD screen. Refer to the image below.

92e23e9.jpg
Now you should be able to extract your power board from the Monitor case and replace any swollen capacitors you find. These capacitors will have 3 identifiers that you will need when purchasing replacements.

1. Pico or Microfarad, usually marked like this (330u)
2. Voltage marked like this (25v)
3. Heat range/Tolerance 105c etc.

These are usually listed like this.
CAP ELECT 10000UF 63V SU BI-POLAR

EXAMPLE PHOTO


Some may be purchased at radio shack, or an electronics warehouse, I use digikey and other suppliers.
Replace and resolder all Capacitors, also checking for loose components before reassembly and resoldering as necessary.

Remember that these components are very inexpensive (around $1.75 to $3.00), which makes this repair well worth the time and effort, even if you fail to make it work. So before you decide to trash that old flat screen LCD monitor, try this cheap and often effective repair and save a little cash.

Good Luck to ya!

Upon startup lcd screen goes linear with different colors then goes plaid w other colors


Probably the screen.

Try connecting an different monitor first, if thats OK your screen has had it.

If the second screen shows the same, it could well be your graphics card at fault, but before replacing, try re-seating it. With luck its just worked loose.

If still no go, then try changing your graphics card, you're now down to the least expensive options.

My monitor turns yellowish i can still work what is the problem. the monitor is a Acer V233H


The red "gun" of your CRT monitor is going bad. You will need to get a new monitor, and you should seriously consider an LCD flat screen. It will save you allot in electricity.

A CRT monitor is a very cool piece of technology inside... even though they are going obsolete with the advent of modern LCD displays.

In every CRT (Cathode Ray Tube) monitor, there is a trio of "Electron Guns"- they fire electrons at the front of the screen, hitting it with billions upon billions of electrons... the "bullets". Each gun is aimed at a set of colored targets, called "pixels"... one gun hits red ones, one for green, and one for blue. Combinations of these colors make up everything we can see.

When the red "gun" cannot fire enough electron "bullets" at the screen, the blue and green together make the picture appear yellowish.

If you want to learn more, look up "cathode ray tube" on wikipedia for starters!

A word of warning- the technology is very cool (I used to teach how CRT screens worked as part of my job teaching Missile fire control radar for the Navy), BUT:

THERE ARE VERY HIGH VOLTAGES INSIDE A CRT MONITOR THAT CAN KILL!!! DO NOT OPEN
THE CASE!!!!

Remember- the electron "guns" inside are shooting billions and billions of electrons at the front of the screen. They are being collected from the screen by a high voltage "supply". Most CRT's operate with anywhere from 15 to 45 THOUSAND VOLTS!

Powerspec 30 lcd tv comes on for a split second, then nothing? Any suggestions on what's wrong?


I would recommend running this free 5 min test from reimage to search for any missing/ damaged files that are causing the installation problem: http://bit.ly/4HWvKz

I am a happy customer after trying the free repair key that reimage gave me to trial on my PC and the result as a brand new PC with a much cleaner hardrive.

My emachines lcd flatscreen monitor is flashing


No. You have a bad capacitor/s on the monitor's power board suggest replacing with new ones. Here is what a blown capacitor looks like. If you are comfortable fixing this yourself, good, you will save money this way. If it isn't a bad cap then it is probably a bad IC.

Water problem


If you want to get the water out you take a chance of destroying the screen. You can take the screen apart but if its in the lcd portion of the screen and not the plastic surrounding it, I would have to say that damage is almost certain. You could look at it this way, if you damage it you probably would have had to get another anyways so heres how to do it. Each model and brand has a different way of getting certain parts off of the laptop so I am going to give you the basics and if you pay attention to what your doing you should be able to get the laptop apart without damage. Unplug your laptop and remove the battery. You should remove the strip of plastic between the keyboard and the LCD lid. Sometimes theres screws that hold this to the computer and sometimes they dont. Once you have the plastic trim removed you shoulld be able to see the Video cable going from the mainboard to the LCD lid. Unplug the cable from the mainboard. If you have WIFI in your laptop there will be 2 wires that go to the wifi card. You should be able to get the LCD out without unplugging these wires and having to rerout the cables when you put it back together. You will need some small Philips screwdrivers. Take the stick on tabs off of the plastic bezel in the screen side of the LCD lid to reveal the bezel screws. Take the screws out and carefully pull the bezel off. There are normally tabs that keep the bezel on as well as the screws. Once the bezel is off then you can get to the screws that hold the LCD in the back cover. You will need to carefully remove the wires from the inverter (normally at the bottom of the LCD) since you dont need to take the inverter off of the LCD back cover most of the time. Once you have the LCD out you can take the tiny screws out of the edges of the LCD. You also should unplug the Video cable from the back of the LCD. Now the only thing holding the layers of the LCD together is some tape. Sometimes its an aluminum tape. and sometimes not but remove the tape from 3 sides leaving the side where the wires are taped. Split the frame apart and you will find that you can get to the different layers of display material. DO NOT PULL THEM OUT! Just lift the layers you have to and wipe clean then blow with compressed air to remove dust. Any dust may show when its put back together. Note: Be carefull because the LCD bulb is located in this area. This is the light that lights up the LCD. If it breaks you will have to buy another LCD. Reverse the process to get the LCD back together and see how it works. I have done what you are asking about to change bad bulbs before. At least the LCD should look better and the worst that could happen is you make the LCD not work and you have to go to ebay and get another. Good luck.

My acer travelmate 2301LMi wont startup properly. effectivly it is bricked.


hi,

presume something wrong with your acer travelmate 2301LMi in two situations

1a.if the case is that you see picture flashing on and off on the screen and shut down and it might be moisture. in traveling in one place to another ( specially cross country) your pc can have that due to climate change / different area temperature.

Tip: in traveling please don't drain power in your battery pack for constant electricity inside your pc and it can help to avoid moisture.

please dont operate in that condition of your pc it might damage your computer (moistured parts). refer to service provider in your area.

if you can dismantle it, then scatter by pcs. and blower (hot) it by pc, but not too close to the computer parts. or dry it in direct sunlight. and assemble it and screw firmly all parts. by doing this please dont touch all electronic parts of your pc coz, its very sentitive to static electricity and might be damage and dont put all parts in anywhere else, make it secure.put ontop of clothes or paper not wet.and not in any metal tables.

1b. if the case is that you see picture flashing on and off on the screen and in the long run shut down. and might be theres some loose screw in the assemble of your pc with contacts. screw it firmly all parts.

2.if the case is that you see colorful brick of codes, letters, numbers flashing on and off and shut down. your video cards is all ready damage. replace it. as stated in the manual.

I have developed yellow dots in screen of new LCD tv what causes this and can it be repaired


I can only assume you're talking about a PC LCD Monitor.
How many yellow dots will tell you whether or not the manufacturer will replace. If it's 20 pixels in the same square inch then you might have a case. Inexpensive unknown brand name LCD's are known to have issues with random pixels. For that matter so have brand name LCD's, but less frequently. Having 1 or 2 bum pixels is not that uncommon. Call the manufacturer, though, You never know!
