Samsung 153V LCD Monitor Power Supply Repair Tips

Troubleshooting Samsung 153V LCD power supply is such as troubleshooting the CRT type. This monitor came with no power symptom. When you first got the repair of this type of power supply, I recommend that you first remove the switching power supply transformer. Then test each component in the primary area before you perform on the secondary area further. You have to be good in testing basic electronic components to detect the disorder.

Youcan always browse through my website only in the event that you try not to know how the basic electronic components. If you do not check the right way, do not know, you can miss a faulty component and you will not be able to solve the problem. After careful consideration of all components in the electricity sector, I found the filter capacitor do not have a reading with digital capacitance meter (open), the two round fuse also idle, 1N4744 15 Volt Zener diode circuit andFinally, the power ic TOP247F blown! Testing the primary switching power supply with a Dick Smith flyback tester shown in green bars indicate good management.

What we were left here, the secondary diode and filter capacitor. Upon checking it with analog meter and ESR meter, they found all in a good condition. Other areas like logic board and inverter board sees it) in order (power failure rarely contribute to these two circle. Now we have confirmed that find only five componentsbe incorrect. Replaced one after the other components were (with the exception of a backup) and just before turning on the power supply, make sure you connect a 100-watt bulb over the live-ac-line, see the photo on my website. Once it is done you can then on the LCD display switches to the brightness of the lamp to look for.

If it is very bright, it means that there is still somewhere short circuit in the power section. If it all goes off or dim, you can now placeCheck your red probe to the secondary side, if all present to their respective dc line. If there are DC voltages at the output, you can switch off the power, discharge the filter capacitor (for security reasons), remove the bulb and connect the new backup to its original location.

You are now a hundred percent sure that the LCD will not bring power to collapse as soon as you turn it on you. Due to the nature of the filter capacitor rated at 105 Celsius, and you can not replace him with the 85 Type C or it will open again after using for a few weeks or months. The ventilation in the LCD monitor is not as good as the cathode ray tube monitor, because the power supply is covered fully by a large aluminum sheet, and it can become hot very quickly. Conclusion as to whether Samsung 153V LCD power supply or other brands of LCD Monitor repair, the procedure is the same. Who knows the power problem in this> Monitor is a common mistake, and in the future, you can deal with this brand of power supply in the shortest possible time. To measure electronic components is not so difficult, but on the original parts like the power ic will get you consume a lot of time.

Customer Review: Excellent Widescreen Monitor (glad I bought it!!!)
UPDATED: June 20, 2009 I have to admit, I was a bit concerned about purchasing this online, virtually sight unseen. I went to Best Buy and saw the 20" version of this display and wasn't overly pleased, but then realized that the demo Best Buy had running on the monitor was not in the model's native resolution. So I came home and after a couple of days of deliberation with myself I took the plunge and bought this from Amazon. The display is a cinch to assemble. I've read some reviews where people have had great difficulty putting the stand together then attaching the stand to the monitor itself. This simply is not the case. Everything is keyed (all you have to do is pay attention to the carved out notches) and slid together very easily, no difficulty at all. "Professional" reviews have indicated that the monitor is very wobbly. This is the case to an extent, but it takes a fair jolt to get this monitor to tip. In all practicality who is going to be hitting the monitor with their hand anyway trying to get it to tip over. Perhaps a good earthquake, a running child or clumsy oaf is needed. Buyers will definitely want to take some time to calibrate the monitor. I am currently running Windows 7 RC1 so some calibration tools are included that don't come in previous versions of Windows (including Vista, that I have found anyway). A Google search for "monitor calibration" will help aid in this process. "Professional" reviews have indicated that gray colors are not represented correctly, taking on a "yellowish hue." Out of the box using default settings this seemed to be the case (you'll see what I mean if you open a picture using Windows Photo Viewer, maximize the window and notice the color of the border surrounding the image), and using the monitor color profile that ships with the LCD (which Adobe Photoshop CS3 reports as being corrupted), but after customizing the monitor settings and getting a new color profile generated by Windows 7, this color turned from the "yellowish" hue to a light blue color as was displayed by my previous LCD (this of course is based on my current color scheme found in Windows 7). Games play flawlessly, with good color, picture quality and vibrancy. No bleeding or blur with this 2ms response time display. The monitor includes presets for gaming, but if you calibrate the monitor properly this seems to be unneeded. Your mileage may vary depending on personal preference, but using in-game settings with brightness, contrast etc. can help get the job done. Games I tested in 1920x1080 were Crysis, the Half-Life 2 series, Far Cry 2, Unreal Tournament III, Stalker: Clear Sky, Street Fighter IV Benchmark (now available for download) and Bejeweled Twist. All played perfectly, again no blur or bleeding. I tested out a HD copy of "The Dark Knight" with no issues, perfect clarity in all respects. Some complaints (again from "professional" reviews) state that there is some white light bleed-through at the top edge of the screen on dark pictures. I found this to be very minor and not distracting at all. My desktop wallpaper images are native to 1920x1080 which is crisp and clear, so you'll probably want to find some HD or widescreen wallpapers for your viewing pleasure. Settings for the monitor I have found to be optimal (at least for myself) are as follows: Picture, Brightness: 50 Picture, Contrast: 76 Picture, Sharpness: 68 MagicBright: Custom Response Time: Normal Color, MagiColor: Off Red: 50 Green: 50 Blue: 50: Color Tone: Custom Color Effect: Off Gamma: Mode1 It may also be advantageous to use the ClearType technology built into Windows (MacOS probably has something similar), again personal preference so your mileage may vary. Windows 7 is a bit more extensive in customizing ClearType than prevoius versions of Windows. I am very pleased with this monitor and would recommend it to anyone looking for a quality display at a reasonable price.

Samsung SyncMaster 910MP 19" LCD Monitor

The Samsung SyncMaster 910MP is not just a stylish display, it is a complete entertainment center all on its own. SyncMaster 910MP helps people enjoy a true multimedia life style and offers a pleasure to look at. It combines simplicity in style with an exceptional picture and sound quality. Enjoy the multifunctional difference in various areas such as office, kitchen, living room, hotel or clinic.
Customer Review: happy at 1st but not later
I bought my 910MP at Office Depot for premium price ($500+) nearly three years ago, and I was satisfied at first, even though the tv pic quality was not great. My chief interest was in computer-monitor use, which was acceptable, and I've almost always used the PIP to watch tv as I do computer work. The PIP tv image quality is much better than full-screen tv on this monitor. Audio quality was mediocre from the get-go, even though I didn't expect much from on-board monitor speakers. Later, the audio began to distort or to disappear occasionally, requiring me to re-power the monitor or to turn the audio volume WAY UP until audio came back ... then back down to listening level. I had a couple of very distracting stuck pixels (RED) dead-center after about a year ... but recently I found a suggestion online to MASSAGE the stuck pixels lightly with my finger, and by golly IT WORKED ... no more stuck pixels YAY! After 2+ years of fairly hard use (at least 8 hours each day and sometimes on for several continuous days), the monitor developed some other video artifacts (horizontal striping or banding) that only appear in tv-viewing mode or with certain full-color computer images. These troubles don't seem to be helped by the MASSAGE. I got what I expected (an acceptable computer monitor with tv tuner), but I felt I had paid too much at $500+, considering mainly the less-than-optimal tv viewing quality and the audio/video problems that have appeared over time. If you get a good price, and if you don't expect too much, this monitor may be a nice deal for you.
Customer Review: Does everything that was expected
We purchased two of these monitors to replace older LCD monitors that stopped working. The monitor does everything we expected. Set up in not intuitive but is OK if you read the instructions. Resolution is good for normal viewing but there is some banding if you are viewing a screen with mostly light colors. This is acceptable as I have observed it on other monitors. It leaves a bit to be desired when used as a TV but the PIP is very good. Again this was the same with our older monitors. I would recommend this monitor if you are looking for a dual function monitor at a reasonable price.
