Re: Samsung 943N
I'm from Romania, voltage 230. On S1 = 932ohm, S2 -> 1Mohm. I can't tell if both S are down, but i think there are, because the spec says that S1/2 = 983ohm.

Samsung 943N
Hi,
can someone help me with the inverter transformer for this model? I can't find it to buy, or equivalent to TM-1017.
Thanks. -
Re: Samsung 2493 HM issue
Analogy with common power supply failure like 245BW. (when you don't figure it out, excalate the problem, search document findings, etc....Leave a comment:

Re: Samsung LN26B460B2D
Check Zenner diodes and the resistor. Picture quality isn't that good. Tell me please the the color band of the resistor placed next the ZD.Leave a comment:

Re: Samsung 2493 HM issue
Please confirm that the big cap is 82micro. If it is, measure the voltage across the legs of the cap (10 sec) and post reading.Leave a comment:

Re: Samsung 2493 HM issue
Please measure the 3 resistors placed around the big cap (i think is 82micro 400-450V?). The resistors are supose to be noted on PCB something like RM801, bla bla. Post readings.Leave a comment:

Re: Asus A6000 wont post
nVidia vs Intel chipset problem. Well, there is a BIG difference: nVidia's problem wasn't solved even in one year and lots of customers suffer from this. Intel solved the P67 chipset issue in couple of months.Leave a comment:

Re: Asus A6000 wont post
The problem of nVidia chips (GPU+chipset) can be fixed by reballing. It's the only solution. Of course nVidia is aware of this.Leave a comment:

Re: Samsung 2232GW
Replace bulging/leaking caps 330/25 with 330/35 or with 470/35 and 820/25 with 820/35 or 1000/35.Leave a comment:

Re: Dell E172fpb
After you replaced those 4 C5707, you have to replace and those 4 caps between c5707.Leave a comment:

Re: Samsung 23" LCD P2350 Inverter Repair
Check the inverter transformer secondaries. I must have around 1.21Koms each.Leave a comment:

Re: Samsung 931BF
Yes, the question was for bad design power supply (sorry for miss understanding). In "pro" series of TV's or monitors i hardly see bad caps, but other component like transformers, mosfets, etc fail. In "budget" series capacitors are on top of failing components....Leave a comment:

Re: Samsung 931BF
Ok PlainBill, i get the point (anyway that was a very good explanation). So, to get a real measure i have to get the ring test. There are many lcd monitor with this problem and i wonder: the transformer is poor quality or the power supply is bad?Leave a comment:

Re: Samsung 931BF
I agree, but the new transformer measure: 1.264 and 1.269 kohm....Leave a comment:

Re: Samsung 931BF
Thanks PlainBill, it seems that measure the resistence on transformer can be tricky....Leave a comment:

Samsung 931BF
I have one monitor Samsung 931BF with the next problem: power on 2 sec then the image is black, but monitor is still power on. I think this is a common problem with the inverter. I measure the inverter transformer TMS91429CT and the results are : secondaries 1.258 kohm and 1.254 kohm; primary 0.2 ohm. These values are ok, everythink else is ok. I replace that transformer with a new one and it's working. I am a little confused, maybe someone can help me to undestand why it doesn't work with the first one.
Thank you.
