Need Help finding replacement parts viewsonic VG150 inverter

[welchs101]

Hi,

I am trying to find replacement parts that are on a Viewsonic VG150 inverter board. The parts i am trying to replace have markings on them but i cant find out any information on them this prevents me from getting replacement parts.

I am trying to find out info on two parts:

Part-1) I think its a transistor: Has the following marking:

"ALG and E1." (see the enclosed pic)

Part-2) I think this is also a transisitor: Has the following marking:

"Y B 124" (see enclosed pic)

If any of you know what these parts i would greatly appreciate it.

If it helps at all i think the inverter board is a Lien Chang LI-2060 inverter board.

Dave

Finally good news

Well, i kept at it and i think i found the soln. Turns out the info i needed was in this forum all along. Someone in a previous forum asked a question about a device with "ALG" markings on the package. This person found the company taht made this device.......it was Korean Electronics company (KEC). So i checked there web site and sure enough BOTH the devices i was looking for were there.

For example:

THe YB device is very similar to the part KTB1124

The ALG device is similar to KTC3875.
