Remove all the mounting screws, stand first, then using thin flat blade screw driver to separate the front from the back starting at the bottom edge and work your way around, be careful on the cable attached to the front bezel. Also look at YOUTUBE on how to open most LCD monitor cases.
Here are the service manuals: http://elektrotanya.com/?q=showresult&megnev=samsung&megnev2=740n&kategoria=&kat2=all

If you are going to DIY 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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My emergency lights keeps coming on their own and the fuel caps opens itself. What could be the problem?


If the fuel cap opens, some autos have a sensor that will see there's no pressure on the fuel system and you'll get a service engine or other light. You probably need to replace the gas cap.

Computer code 455


Possible causes - Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking The P0455 it's a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.

When is the code detected? EVAP control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors P0455 Buick Description This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition. The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.
if tightening the cap or replacing the cap does not help take your car to a shop to have it diagnosed as it requires special tools/equipment to test this and get an accurate results to find what needs replacing.

High pitched whine not from a fan or hard drive


It is possible that you have a bad component on the motherboard.
Sometimes you can hear a noise like this when a Capacitor (CAP) is malfunctioning.

If you are able to open your computers case; you can look inside at the motherboard, you can see if a CAP is malfunctioning by looking at the top of the CAP (there are many). If the top of the CAP is not flat or has brown marks (not silver/original in colour) then it could be bulging or leaking and needs to be replaced.

There are CAP's in the Power Supply as well but these are not user serviceable... just replace the power supply. If you are handy and feel like you can fix it anyways, just remember that CAP's store a lot of juice and you could be seriously injured!

1. Verify fluid level in brake master cylinder. Top off with DOT 3 brake fluid as necessary. Leave cap off.

2. Raise vehicle on hoist.

3. Remove bleed port protective cap and install suitable size and length of clear hose (4) to monitor and divert fluid into suitable container.

4. Open up the bleed circuit by turning the thumb screw (3) counter clockwise this will start the air purge and fluid fill process.

5. Lower vehicle, but only enough to gain access to and fill the brake master cylinder. NOTE: Do not allow clutch master cylinder to run dry while fluid exits bleed port.

6. Top off brake master cylinder fluid level while air is purged and fluid drains from bleed port. Continue this until no air bubbles are seen and a solid column of fluid exists.

7. Close hydraulic bleed circuit, remove drain hose and replace dust cap on bleed port.

8. From driver's seat, actuate clutch pedal 60-100 times.

9. Apply parking brake. Start engine and verify clutch operation and pedal feel. If pedal feels fine and clutch operates as designed, stop here. If pedal still feels spongy or clutch does not fully disengage, excessive air is still trapped within the system, most likely at the master cylinder.

NOTE: Use Bleeder Container To capture hydraulic fluid and Transparent Bleeder Hose To route fluid to container.

6. Turn on the service filling machine.

7. Crack open the bleeder valve (3).

8. Allow fluid to flow out of bleed port until no more air bubbles can be seen in the transparent bleeder hose.

9. Once fluid is free of air bubbles; make 15 quick actuations between clutch pedal stop positions.

10. Close the bleeder valve and disconnect the service filling machine.

11. To remove remaining air, actuate pedal 10 times slowly between pedal stop positions.

12. Check clutch pedal to see if vehicle is properly bled.

13. If vehicle is not properly bled, repeat procedure.

14. Remove bleeder cap from reservoir and replace reservoir cap.

15. Disconnect transparent bleeder hose from bleeder valve and replace dust cap.

How do I remove small cap on steamer valve, to replace washer?


Simply use a small flathead screwdriver to press one side of the dial insert to remove the dial cap. Under it you have a flathead screw. Remove this to remove the cap. Then use a 20mm socket or open ended wrench to remove the nut. Unscrew the union valve then you will see a seat gasket in the front, and an o-ring on the valve on the back - this is what you are looking to replace. You can contact me if you have any further questions.

1994 Chevy Silverado Gas Cap Unavailable?


Autozone or oreily just any gas cap just about will do. To force open use a flat head screw driver, hammer and pliers. Drive the FLAT tip screw driver into the gas cap and use the pliers to turn. These vehicles did not come factory with locking gas cap so some one has replaced it once before. Don't worry the worst you can do is ruin the gas cap which is no good to you any way.
