Re: LG 42PT350R clicking on/off
Hi guys,
Currently facing same problem with my LG. Does the VA and VS should always show the voltage? When I connect anything (like Z-SUS, Y-SUS, main board) the VS and VA drops off under 1 volt. I have checked ALL capacitors and all of them are fine. the fuses are good. What that could be?
Thanks in advance and sorry for opening the thread all over again.Attached FilesComment

Hi,
First post...
I have this TV, which was working, then suddenly would not turn on. It would get the clicking relay then flash up the screen for less than a second, off for a second then on again. Removing the plug the relay continues to click on and off for a few cycles, which I don't think it did before.
Left it a few months, then finally got round to taking the back off, and it worked as it should. So I tested various bits and all was well. Then turned it on again, and back to the clicking relay.
I disconnected the main board from the power... -
Did some of the usual troubleshooting.
Unplug main board connector and back lights come on and stay on and PSU supplies all correct voltages on the legend.
When you just plug in the TV the PSU relay clicks on and off immediately and then continues to click on and off every 20 seconds or so. The red light on the front flashes once and then 5 to 8 seconds later flashes once again and continues the cycle with the relay.
I've disconnected each you ribbon cable one at a time and every single T-Con cable one at a time to see if there's any change. No change as long... -
Hi,
I have this OLED in standby. With remote or local button it tries to start, relay clicks but switches off again immediately. I have noticed 24V dc out missing . But this was due to a missing signal from the mainboard at DRV-ON signal. If I apply 3.5 volts 24v is on but same result. Have disconnected TCON cables one by one but still same issue.
Is there any mainboard reset procedure or testing please as am new to this model.
Tks!... -
Hello, I bought this Mac from a friend, he said that it simply stop working. The MacBook looks very clean but does not power on, stuck on 5v 0.42A, and sometimes display 5V and 0A (then 0.071A and again 0A).
I opened it looking for some problem, it was not touched before for sure and the board is very clena, no spot of corrosion at all from what I can see. Voltage on multimeter of the board off the case it's the same, 5V 0.42A. But then I noticed this "clicking sound" come from the board ( I attached here the audio file).
Looking on google I found this:... -
Hi i have an issue with LG 42lw4500 wich after pressing the power button flashes red then goes solid white light 2 clicks and nothing , the weird thing is SOMETIMES if i leave the tv plugged in it would come on and fuction normally (i should mention that vertical rectangle going from the bottom to the top of the screen have some red dot artafacts it only appear in somthing like the tv input menu and any input i give like vga , but not in the system menu , i thought i should mention this , i cannot confirme if the tv had this issue when it was up and running in its previous owner . ) when checking...
