So, my LG OLED wallpaper TV was on in the background, and at one moment it just died - picture turned dark, no sound, nothing. Its speakers, that normally slide down when TV is off, were just stuck in the drawn out position. Pressing the remote control on/off button yielded red LED blinking a couple of times (I think it's couple of times, this was actually some time ago) and that's the only sign of life.

Unfortunately TV is out of warranty period, but I took it to the official LG service shop, to diagnose the problem. They needed to wait for some extra part to be able to do it (whole...

Re: samsung 32 ln32b360c5d no power no indicator

Thanks guys on all the help. I'll go out tomorrow and get the caps for it.

Two questions though:
1) What is the cold and what is the hot part of the power supply? I mean in general? in this board I presume that would mean exchanging those seven caps in the lower left in my picture?
2) Can I put higher voltage caps in place of the lower ones? E.g. I have a 1200uF 35V one available, and CM852 is 1200uF 10V while CM876 is 1200uF 25V?

Edit: Success! I replaced that single cap, and now it turns on....

Here is also a picture of the board. Area around those fishy diodes is suspiciously darker than the rest of the board, as well as the area to the top of the leftmost cooler in the picture. Bottom of the board has no visible damage anywhere. Top of the CM852 (1200uF, 10V) capacitor looks slightly convex (other capacitor tops are concave), but it doesn't look blown to me....

Re: samsung 32 ln32b360c5d no power no indicator

Hi all. I'm a complete n00b when it comes to this, so bear with me.

My father has a Samsung LE32B350 TV with a BN44-00289B power supply inverter. It started going crazy - turning on and off by itself, and then after a week or two it went completely dead.

I took the board out connected it to mains, and got the following DC voltage readings from the CN802 pins with black probe on pin 16:
1 - 0,77
2 - 5,20
3 - 0,00
4 - 13,19
5 - 0,00
6 - 0,00
7 - 5,20
