How come the transformer winding resistance readings are showing in V (Volt)?

I've just changed a TM-10160 in a Samsung T260 today.
You need to measure the resistance between pins 2 and 4 and also between 6 and 8.

The resistances should be very close, which they are not. Suggests the transformer is faulty.

+1, you have bad transformer. The reason for bad winding can also be due to bad lamp drawing too much current, so when you install the new one you should check the temperature.

+1
thanx

you're right. today i measure old Philips 170S 's transformer and see same number.

i think this is suitable..

I hope the shipping will be a lot less shipping to your country.
EBAY has them too.

no.
shipping is only 1,89 $ .

it's weird that 2-4 are 5800 ohm after the 2 caps desoldering and resoldering,

at new one

2-4 1134ohm
6-8 1140 ohm

Problem solved. Thank you very much indeed.
