    LG 60PN6500-UA Won't Turn On Standby Only

    Hello. On this set when I press the power button the TV does not come on. The standby light remains red. I think mainboard (eeprom) but I'm no expert so I'd really appreciate some help to troubleshoot this TV so it can be repaired. Thanks in advance.

      Run the test patterns. Unplug the cable going from the mainboard to the logic control board and put a piece of wire in the holes circled in red. Plug the tv back in and the patterns should come on. If they do, your mainboard is bad.

          Genius. Saw test patterns on my 60PN. I did see another post where someone used a 50PN6500 mainboard and it worked no issues.

                  by PNI E.
                  Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal. On...

                  Harman Kardon AVR 171S - standby led lights up, does not turn on
                  by madsox
                  Greetings!

                  Thank you in advance for your understanding, I am writing to you through a translator.

                  A Harman Kardon AVR171S amplifier was given.

                  The history of the machine is as follows:
                  It was faulty when I bought it, I want to fix it.
                  I replaced the HDMI switch and one of the DAC ICs in it.
                  After that it worked without a problem.

                  I watched a movie using the amplifier, and at the end the amplifier got really hot.
                  The cooling was faulty, I will fix this later.
                  I switched it to standby mode, waited for...

                  un60j620dafxza - Samsung No Display Problem
                  by stylishconsultant
                  Hi All,

                  Need help.

                  I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

                  So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
                  problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
                  might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....

                  No Standby Light on Samsung UN65MU6300FXZA with Mainboard BN94-12440E
                  by Michael Long
                  I had a Dead Samsung UN65MU6300FXZA with Mainboard BN94-12440E
                  Dead / No Power / No Standby Light results after power company had three
                  consecutive power outages on/off/on/off/on/off after which TV was rendered unresponsive.

                  After exploring the issue found Mainboard was the fault. Then with research on this site determined IC1604 was the suspect. The IC1604 is a surface mounted device (SMD) EEPROM, Winbond Model 25Q40CLSIP. A read on this EEPROM came back with all FF FF FF FF FF in all registers blank and empty of data. I had a spare mainboard with intact IC1604 and utilized...

                  Xbox Series X Console Won't Turn On - Broken Nexus Connector on Mainboard
                  by gabri2211
                  Hello everyone,
                  Inside the console there is a small circuit board (see photo) that contains the main power switch, the one on the front.
                  This circuit board connects to a 10-pin flat cable called NEXUS that terminates on the motherboard.
                  This NEXUS connector broke.

                  Can anyone tell me, while waiting for a replacement, if it's possible to turn on the Xbox by disconnecting this circuit board and making some modifications (like adding a small power button) on the motherboard?

                  The Xbox has a power supply that provides 12 volts on all outputs, so the power...
