Default Samsung DVD-511 burned resistors

Hi PRR15 and PRR17 1/8 watt resistors in power supply primary burned
beyond recognition. Anyone with a similar model can tell me their
values? Exact model no. is DVD-511/XAA though I presume any DVD-511 or
DVD-711 or maybe other models may have the same power supply
components.

Thanks in advance.

Ouch!

Checked out the secondary to make sure it's okay?

Also, you may want to consider the player as a lost cause. The DVD-511, as
well as many other Samsung players, were horrible when it came to the quality
of their optical pickups. This player may have a worn pickup on top of the
power supply problem. - Reinhart

Not to mention the shorted spindle motor, the likely cause of the burned
resistors.

OOPS. The resistors are in the primary. Sorry, probably the switcher is
fried.

sorry, I failed to mention the cause of the frying. the unit is a
brand-new US-made 120V model accidentally plugged in to a 220V outlet
standard in our country. The owner forgot to use the stepdown
transformer. You're right switcher is fried but I've got a
replacement; just need what those resistor's values are.

Well, I used to have a busted DVD-511 which had a functioning power supply.

I can try to locate it and give the values of the resistors themselves.

In the case of an overvoltage condition, you may also want to check the
condition of other power supply parts, especially any electrolytics and
varistors in the primary. - Reinhart

Oh, wow! So I'm not the only one who saw this problem up close and personal.

There was another DVD player that came in for a problem and it was a DVD-511
with a shorted spindle motor. - Reinhart
