HP LA2306x having shorted diode. Compatible replacement for Diode MBR5200.

[newbie1]

Hi guys.

Need your advice. I am repairing a HP LA2306x having a shorted diode. Diode marked MBR5200.
Link http://www.alldatasheet.com/datashee...R/MBR5200.html

May i know what is a suitable replacement that can be found at either Element14 or RS components?
Thanks in advance.

Perhaps others can help I have looked and can find no 2 legged (single) schottky diodes
perhaps you can get away with using one half of a dual?? - perhaps someone will know?

You could contact manufacturer - all their outlets seem to be in your part of the world

Possibly ISL9R1560P2 or ISL9R1560PF2 (isolated) might fit, but I don't know about their availability at stores mentioned. However forward voltage VF value is bigger, which might be an issue.

I ended up buying the same model. Replaced it and it fired up nicely.

Sorry to bring up a old post but i was wondering what the problem was as i have just been given one to play with. The picture is fine on the left hand quarter and the rest of the screen has vertical lines down it, there is no visible damage and i tried the usual pressing round the edge of the screen etc...

OP had a bad rectifier diode. I presume it was for the power supply.

Try cleaning up the LVDS cable between the logic board and the t-con board. If not, it could be the LCD going bad.
