D201 Diode For Gateway FPD1975W/900W?

[lcdman]

Hello Fellas,

I have a Gateway FPD1975W or 900W inverter board that has a burnt D201 diode, I haven't had any luck finding a schematic for this monitor. Has anyone worked on one of these before? I need the value for this diode. Its black with a grey line on it,and has a ferite (SP?)bead on each side of it. That is all I know about it.

Thanks As Always
Lcdman

Hint 1: Many manufactures use more than 1 power supply / inverter board in a given model of monitor. A picture will tell us much more than only a model number.

Hint 2: The application notes for the inverter controller and the power FET may show recommended components like diodes.

Hint 3: Most diodes are either black plastic or glass, and have a band at one end.

MIRAGE 190DTLB?
dam cheap here from this guy... shipping a bit high...but unlessn you are sure its that... I'd honestly say I'd buy that one:

Are you sure it is not ZD201? That is what is fried on mine and I am still trying to identify.

Either way, can you look at your board and see any markings on ZD201?

Please!!!

seems like I might have a board laying around for that...along with a vid card... screen was flash to white then went out... I used the screen for another monitor. parts avail cheap to anyone that wants! let me know, I'll double check.

If you have a board, please look at ZD201 just above the header pins and see if you can see any markings.

Mine is burned beyond recognition.
Here is a pic.

Hello All,

First off sorry for no photo! Second, my board doesn't have a ZD201. Sorry.
Also its D204 not D201 as I posted before. My bad. I'm including pictures this time for all to inspect and comment on. Be kind!!! Thanks to all the fellas for the replies so quickly.

Take Care

Hello AWD Guy,

I went through my other boards and found one like the one you had a picture of. ZD201 has the numbers: LT52l0 & P6KEl2A under the LT52l0 Hope this helps in your search!

I see you have D204 removed. In that case, check the numbers on it and post them here. Otherwise, post a picture of the back side of the power board - this will help determine what the function of D204 is.
Also, was Q201 blown as well?

Thank you so much! P6KE12A is Motorola 12V 5W Zener! Off to update my thread in case somebody else ever searches for the info.

Hello Again,

Sorry for the delay in posting. Yard work, oil change on my car. Yes Q201,D204 were shot. D204 doesn't have any numbering on account it was fried! Maybe these two additional photos of the bottom of this board will help to identify D204?

D204 should be the same according to that schematic above linked

Yes, thanks.
Looks like D204 is the snubber diode, so you need a fast recovery rectifier rated for at least 1000v and 1A forward current (I would recommend 1.5A just to be safe). FR157 is rated for 1.5A and would probably work fine. PR1507G and UF1510 have the same ratings as well. A slight upgrade would be PR2007G, FR207, UF2007, and UF2010, which are rated for 2A, 1000V.
There's probably other choices as well, depending on where you buy from. If you have any junk power supplies, have a look in there first - they often have similar diodes on the primary side near the switching transistors.

Forgot to mention... Check C202, D203, and ZD204 for short circuit. Also check the SMD resistors to see if any are open.
