Re: LG 50PX950 Clicks, Turns off instantly



Today in another shop i found a Diode 1N5819 and they assure me is the same of the SR/SB 140... is it so?

Really much thanks for your patience

I have taken, for eventual replacement at the weekend, the diode and the transistor

The Diode was to be SB140/SR140 and the Transistor 3BR 1565JF

The Transistor has the correct code, even if the vertical code is different from the one they give in the kit on ebay.. I do not know if it is important.

They gave me a 5A 100V diode... I noticed it and I went back to it.... and the girl told me that this is better and that if the technician says that it is not good to call her, she will explain it to him......

Hi,

i can do this test only in Weekend, now here with me i have only the Amp board.
I give you some more information.
When I turn on the TV, the red light comes on. Then for several seconds the remote control is as if inhibited. I notice this because the red LED turns blue when it receives command from the remote control.

In the center of the TV is a large blue LED that lights up at the beginning, and then goes off....

I look at this video where it says to check the diode D304.
I...

Hi dear, i just tried and from all 3 resistance, i get beep



The control board, is the one on the right?



I hope u can drive me to repair it.... :'(

Hi dear,
Idisassembled the motherboard and checked the 3 resistors. Initially the values, with two different multimeters, changed continuously up and down.... starting from 100 and after a few seconds it progressively reached 200...
After a while I tried again, and this time they seem, unfortunately, all 3 ok.Between 11.5 and 11.6 ohm 😢
What do we invent now?




Thanks much

Re: LG 50PX950 Clicks, Turns off instantly

Hi guys, I also a 50px95n. Yesterday morning it worked, now it does not turn on anymore. I hear the click of the relay, but it remains black. It is a 3d plasma.

For some time it had a strange defect, when it was turned on the image would flash fast, then after a few seconds it was fine until I turned it off. Sometimes I had to turn it on and off several times to make it start well, but once it started it was perfect.
Sometimes, more often when I turned it off, the relay was slow to click... maybe 4-5 seconds after...
