    LG 60PN6500 Plasma, does not power on, red light stays on.

    Hello! New here, hope I can bring my TV back to life!

    My LG 60PN6500 TV suddenly died. The front small red LED stays on. The POWER button either on remote or on TV doesn't to anything.

    I've tried troubleshooting it, but I'm a bit new to TV repairs. My main board, the one with the different outputs is getting it's 5.2 volts on the pins they should and also it's 17volt.

    There is M_ON and other pins that I don't know how to test.

    When I disconnect the main board from the power supply, I can hear a relay clicking and a kind of hissing sound comming from the the 2 other big modules on the side that looks like other power supplies. I think those modules are called YSUS board but I have NO IDEA what they are for hehe, sorry.

    Where should I be looking for? I'm pretty handy with a multimeter but new to TV, so some help might help!

    thanks!

    G.b.

      We need to seem clear, focused close up photos of the PSU and the connectors and the other boards as well.

          Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
          by Alicat
          Hello,

          Stopped by this site trying to fix my parents Panasonic Plasma TV.

          Model number is TH-50PZ85U

          Power comes on and the red power light stays on solid.

          Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

          I also hear a few clicks.

          I also think my parents said there was a thunderstorm and the TV failed after that.

          Section 6 in the service manual talks about power and no screen,...

          LG 60PN6500 Plasma with standby, but won't power up.
          by XCon
          Symptom is TV has standby, I get relay click, voltage rails come up, but no screen and TV shuts down after 5 seconds. If I disconnect the Z from the y sus, the unit stays powered up and I can read voltages.

          So I've read the two other threads on this TV and I can confirm the Y-Sus #EAX64789501 does not have diode or resister failure. Did not see any fractured solder joints on the transformer or anywhere else. All power boards have slight discoloration on the hot spots.

          The board in question is EAX64789601, Z board. I have 208 going to Y Sus, 5v standby. Pin 5 on P174 connector...

          Lithonia Lighting versus Light of America Compact Fluorescent product quality
          by sam_sam_sam
          I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent

          I also have back when Light of America had these light bulbs available for yard lights

          The issue with Light of America was the blast boards had all most certain board failure while bulbs hardly ever fail

          While the Lithonia lighting fixture has all most certain bulb failure

          So I have modified the Lithonia lighting fixture to accept the Light of America light bulb and see how long this will last

          I have only had this light fixture for not more than a year if it...
