Fixing power problems with your LG Flatron Monitor (LG1753S)

lopau — Mon, 19 Jul 2010 07:44:36 +0000

A couple of days ago during the weekend, I booted up my trusted pc lo and behold I heard the Windows startup sound but my LG monitor (LG1753S) screen is blank. I had this monitor for about 3 or 4 years now without any glitch. Used to leave it open for 72 hours sometimes. And this time it had failed to start up. So after checking the power is properly plugged, I shut down my pc again. Turned off the EPS and turn back on, the monitor power lit up(hooray?) but after a few seconds its gone again.

So its final my LG screen is dead. After a couple of googling on my alternate internet device(HTC Hero) I found out it’s easy to fix. Thanks to this website for the amazing archive of fixing LCDs. http://www.ccl-la.com/blog/index.php/lg-l226wtq-bf-monitor-repair/. Just several capacitors failing me, being the jack of all trade that I am I decided I’ll fix it myselft. I went to my trusted electronics shop and purchased some capacitors according to the article, but found I it was the right one. LOL. I opened up the monitor and upon inspection the capacitor ratings are 4 1000uf 25v, 1 470uf 25v and 1 680uf 25v high temp. So back to the electronics shop. So after removing the old capacitors and soldering the new ones. The Monitor is good and alive again. Took only atleast $3 for the whole thing.

Took some snaps while I was at it.

So a little bit of guts and the need to save on service fee, just DIY(Do-It-Yourself), make sure you have the right tools, a philips, screwdriver, soldering iron, soldering lead and check the ratings of the capacitors before purchasing.

Capturing from a miniDV to a PC

lopau — Thu, 19 Nov 2009 13:27:25 +0000

Well this is sort of a short review and a tutorial on how to capture from a minDV Sony handycam to your PC.

But before that here are some background. I still have this Sony DCR-HC48 camcorder that I bought couple of years ago back when HD camcorder were still pretty expensive about $800-$1500. With the Sony DCR HC series you can transfer video only with a i.LINK cable to firewire. The USB cable is only used to transfer still images. Firewire offers the best quality video transfer unlike USB methods for capturing from still tapes.

To get started on a PC you need to an i.LINK cable, a good capture card and a good capture software, I suggest you go for the PCI-Express capture cards and not the PCI version as it would soon be obsolete, plus PCI-E is more faster.

The one I bought is a Belkin 3-Port firewire PCI-E. So just open up your pc and install it on the PCI-E slot. It’s plug and play so no required drivers when you start your PC.

Belkin 3 Port Firewire PCI-E Card

Installation

i.LINK Cable

For the capture software I used the software that came with the Sony DCR, I found that it offers better depth than Windows Movie Maker. I didn’t try it yet on commercially sold video editors which has built in capture features.

Below is a sample video captured then I re-saved the file using Windows Media Player to reduce filesize but with a bit of quality loss. (btw the one with fairy costume is my daughter)

Overall that is how to get started. The firewire PCI-E is amazingly fast and produced no drop frames. Windows Media Player capture quality is kinda poor so go look into other capture software.

On a different note I used to use an MacBook Pro before for capturing videos. Another reason why I love a Mac which by review comes with almost the complete ports which includes the i.LINK firewire port plus comes with a free powerful software iMovie for capturing and editing movies.

How big is a petabyte

I heard about terabytes which is 1000 gigabytes, but not petabyte. With all people storing music, taking pictures, storing videos, HD movies, games etc, documents, database backups etc on to their computer. It’s amazing how storage needs to get bigger and bigger to accomodate these files. Mozy one of the leading online backup services I use posted on their blog an interesting stats and chart on how big is a Petabyte and how much you can store.

Read it here

One petabyte is roughly one thousand terabytes, one million gigabytes, or one billion megabytes. That’s the space of 10,000 laptops, each with a 100 GB hard drive, on which you could store approximately one of the following:

# 13.3 years of HD-TV video
# 10 million yards of books on a shelf
# 20 million four-drawer filing cabinets filled with text
# 250 million mp3 songs

Jaw dropping..

HP Mini 2140 unboxing review

lopau — Tue, 21 Jul 2009 16:30:13 +0000

In the spirit of unboxing new gadgets, I’m posting some unboxing photos and my review for the HP Mini 2140 I got for my wife. After researching the best bang for the buck for what UMPC (Ultra Mobile PC) to get. Commonly known as netbook as a more general term but other PC makers don’t want to call their products as such. Narrowed down my choices to the HP Mini 2140 10.1 inch and the Gateway LT3102i Ultra Slim Laptop 11.6″. But after much comparison I went with the HP Mini 2140 considering the sleek aluminum design and the keyboard size plus I prefer HP products.

Here are the some box photos and side by side with my antique reliable Compaq Presario 2100us for size comparison.

Technical Specs:

Model Name	HP B2140 Mini Note
Display	10.1″ WXGA LCD
Processor	Intel Atom N270 processor (1.60 GHz, 512 KB L2 cache, 533 MHz FSB)
Chipset	Intel
Graphics	Intel Chipset GMA 950
Operating System	Windows XP Home
Ethernet Communication	Broadcom 10/100/1000 gigabit Ethernet
WLAN	Broadcom 4311 A/E/G/N Wifi, Bluetooth 2.0
Memory	1024 MB (DDR2)
Storage (Hard Disk)	160GB Mobile 1.8in.
Camera	Built-in
Audio	Hi-Definition audio Stereo speaker Built-in Microphone
Battery	3 Cells: 5200 mAh, 2hrs* * Actual battery life will depend on actual operations and other settings.
Ports / Weight	1.19 kg / 2 USB 2.0 / 1 microphone in / 1 headphone/line-out / 1 external VGA monitor / 1 RJ-45 / 1 AC power / 1 Express Card/54 / 1 secure digital

The Pros:

Sleek all aluminum lid, solid magnesium alloy chassis makes it durable plus the brush finish gives it an appealing look.
Nice keyboard implementation, almost 92% as big as the normal sized laptop keyboards. Keys popups nicely on each tap.
Weighing in at just 1.19 kg so pretty light.
Fast charging.

The Cons:

Because of the almost fullsize keyboard squeezed in. The mousepad room was designed in pretty a awkward left and right buttons. Requires practice to use with one hand.
The screen resolution is a couple of pixels short 1024×567 from the standard 1024×600
3 Cell Battery life would last only 2.5 hours. Option to get 6 cell but that cost about 4K more.
When charging the undersides gets warm.

At P23,995, it’s worth it from the almost identical specs of netbooks in the market. I shelled out P1,300 more for upgrading to 2G of RAM plus P500 more for the ultra cool HP pouch bag which I think should have just been a freebie.

Just got a new SATA drive, if you have your primary drive as an IDE and install a new SATA drive, it won’t show up instantly when you go to My Computer. That is because the drive is not formatted yet. To fix this you need to format the drive and assign a label. Here are the simple steps.

After the device has been detected and reported ready for use.
Go to Start > Control Panel > Administrative Tools > Computer Management

Next select Disk Management under Storage. Your new sata drive should be detected. Right click on the drive and choose Format, follow the wizard steps and give the drive a label.

That’s it. Once done your new drive should show in the My Computer and ready to use.
