Fujitsu Scaleoview L22W-3 inverter fail

[dondrusco]

Hi, everybody.

I smoothly moved from level one - bad caps to level 2 - not working inverter.
There is FSP055-2PI02A power board with inverter. I recapped it, but it still won't work. It starts only for 4-5 seconds and then turns CCFL off. During light on it hazzles silently. Inverter logic chip is MP1038EY.

I want to replace those two N-MOSFETs, but I can't read type of them.

Have you any suggestion, what type of MOSFET to use?

Thank you

Re: Fujitsu Scaleoview L22W-3 inverter fail

Hi,

I measured backlight transformer once again, and there is the problem.

One secondary circuit has resistance 1kOhm - it is OK. But the second one has more than 10kOhm.

The type is SPI 8TC00332. I found it only in the United States. Is there any option to buy it in Europe?

Thank you in advance

Re: Fujitsu Scaleoview L22W-3 inverter fail

Fine, repaired.

I ordered new transformer from lcdparts.net
Now it works fine.

hello dondrusco

J break down same that you

I have were on the site my steps of SPI 8TC00332

you can informed me about the American site

thank.......... "french"excuse me

Hi,

No problem with lcdparts.net site. I ordered new transformer and paid by PayPal.

http://lcdparts.net/TransformerDetai...ProductID=2796

It arrived within one week. No customs - amount was within free customs range (25 EUR)

Re: -3 inverter fail

Can any one help please, I have a Fujitsu Scaleoview L22W monitor with a power problem, The board number is FSP055-2PI02A. The power FET has blown and I am can not see any part number.

Apparently, this board is also used in the Acer X221W and X222W. Maybe someone who has this model monitor can chime in.

Re: Fujitsu Scaleoview L22W-3 inverter fail

Not a FET.

TOPSwitch.

Report mains cap brand and series please.

Re: Fujitsu Scaleoview L22W-3 inverter fail

I'm holding an X221W power supply in my hand right now. The IC in question is this:

First line:
F 1 H06

Second line:
CM0565R

Re: Fujitsu Scaleoview L22W-3 inverter fail

Fairchild - CM0565R - Power Switch

aka: TOPSwitch for all intents and purposes.

PDF attached

MOSFET Switcher, PWM combo

Not finding anyone with stock. Most are storehouses that want to sell you $300 - $1000 or better. Not one piece.

Re: Fujitsu Scaleoview L22W-3 inverter fail

You can probably replace it with an actual TopSwitch or maybe ST Viper series, just requires some careful reading of datasheets.

Hello, i have same board to Acer, the component is:

first line:
F1 G47
second line:
CM0565R

Thanks for all the help finding the part number, I can not find any one with them in stock.

Re: Fujitsu Scaleoview L22W-3 inverter fail

Hi, This is my first message here and I have the same problem than dondrusco had with a L22W-2 monitor, the lights shouts down after few seconds.

I saw how to solve it and I only need to order the transformer. I just wanted to ask if that tranformer is ok for every L22W monitor or maybe it's different for the L22W-1 and the L22W-2 and if it's like that how can I see which transformer I need?

And maybe that's not even the problem in my monitor.. I saw a guide here with all the problems that can cause the screen to shot down. There is an easy way to understand if the the transformer is the problem or not?

Thanks!

Re: Fujitsu Scaleoview L22W-3 inverter fail

You are correct - it could be many reasons- Does you transformer have any numbers on it.

Re: Fujitsu Scaleoview L22W-3 inverter fail

Really thanks for the good welcome! Here the images:















I hope this helps. Because I guess it's not so easy to understand what's wrong in that from some images. It seams that the component are not burned or broken (from the outside).
