Re: Samsung LE37M86BD wont turn the screen!
1) ..can you see the DVD playing without the backlight on? [B]nothing[/B]
Try shining a flashlight on it. [B]didn't help..[/B] Is there sound? [B]Yes[/B]
2) Circled in red are some ICs. What is the part number?
[B]P2804ND5G, N- & P-Channel Trans.[/B]
3) circled in [B]yellow[/B] are SMD fuses. [B]3A/32V, all are OK[/B]
[B]Is it a good idea if I disconnect all inverter channels by disoldering those 3A fuses, and test only one ch. at a time?[/B]

Re: Samsung LE37M86BD wont turn the screen!
Hello people. My Samsung LE37M86BD TV has got black screen. The power supply provides all the voltages needed to, but it will not turn on, even though the "Power Button" you can see that it is on! There comes a glimpse of the backlight for a few milliseconds and then disappears.
Is there anyone who knows about this?
Thank you in advance.

Re: Samsung Syncmaster 245B Black screen and blue Power LED
Thank you mr. PlainBill.!
U're a genius...It was right. I changed CM802 (18n 630V with a 22n ) and it's working now!

Re: Samsung Syncmaster 245B Black screen and blue Power LED
The model number of the power supply is BN44-00173A. The Prim. DC-supply is ok, otherwise there 'll not be any 5V st.by- supply! I can also measure pulses around L801 & TB801S and the prim.side of TM801S (not at pin connected to RM814), and no pulses at sec.-side of this trans, that deliver the +5.3V & +24V DC! I need a schematic on this board if anybody could help me with that!!??Leave a comment:
