My PV1000 does power up when plugged in. Can you send the wiring schematic and troubleshooting guide.

Ok you are going to need these items before we begin. digital multimeter, and the schematic of your set. These items are the bare necessities for troubleshooting this problem. If you are uncomfortable around electricity, don't even attempt troubleshooting the set. Ok the thing you need to do first is: 1) get the schematic of the TV set (Call the manufacture to get this) 2) get a digital multimeter (your local radio shack will have this) 3) take picture of the circuit board so as I can have a visual guide by which to help you locate components. 4) send me a copy of the scematic so as I can guide you through the troubleshooting procedure. Ok get these items and we can begin.

the key when on sends power to the ecm electrical control module this in turn sends it to the coils and then to the spark plugs get a wiring schematic for your quad and rehook them up to the key

Just fixed my PV1000 that would not power on. Verified 185vdc on bulk capacitors. Measured 11vdc on U5 (UC3842) from pin 5 (gnd) to pin 7 (vcc). Then measured 0vdc from pin 5 (gnd) to pin 8 (ref). This should be 5vdc. This means that U5 is shut down for undervoltage. Turned out to be two open resistors. R94 100k 2w and R77 33k 2w. Never would have guessed that as there was no sign of heat discoloration. They are next to each other between U5 the UC3842 PWM IC and Q3. This prevented the proper startup voltage for U5. Replaced them and I'm off and running once again. Hope this helps someone.

I do not have the schematic, but have a testing / troubleshooting guide for the 60PC1D 1st and 2nd generation, which gives some good insight in organization and functionality of the power boards.

This is what we ourselves step on when repairing - LG often does not publish schematics for power boards and sustain boards.

contact us if interested

I have the same problem. La Mars covers the factory repair for these. Their number is 712-546-1644. Have you fixed your problem yet ?

Just a hint to troubleshoot: Connect a 100 Watt light bulb in series with the hot side of the power line into the amp. Make a cord with a light socket and a receptacle to plug the amp into. This acts as a resetable fuse and will send enough current through the amp to not fry stuff, but enough to do troubleshooting.

Not sure about schematics but here are a couple links to disassembly guides:
