The transistors are in a package equivalent to a Sanyo PCP
http://datasheet.digchip.com/413/413...-0-2SD2099.pdf The
transistors have identification that looks somethng like this:

DK

QH


Sanyo PCP1201:

Frank,

Thanks, I'd already found that information. There are reasons to
believe that is not the proper part.

1. The power supply / inverter circuit board has a 12/01/2003 date on
it; the monitor was built in May, 2005. Sanyo indicates the PCP1201
has a status of 'New'.

2. AFTER posting this appeal I found pictures of two inverters from
Compaq TFT5010 monitors. These use the identical circuit (but a
different layout). One of the inverters has 4 transistors labeled DK
QH. The other has 4 transistors labeled DK QG. My initial conclusion
was the QG / QH is a date code. The QG is used on the same package
for the 2SC6096

Wahoo!!! The package is SOT89. Mouser Electronics' search engine
shows tiny pictures of the components that match your parameters. I
found a PBSS4480X is available in the proper package and appears to
have (superficially) the proper specs. Now to see if the package
markings match.

Thanks,

PlainBill
