So, where is this edit button that is suppose to be here? Why can't I just add a file without having to post a reply?
This is the service manual for the following units with schematic and board layout
42” 42PFL5704D/F7

Edit button goes away after a pre-determined time.
Main board schematics are as scarce as hen's teeth!Comment

Re: Phillips 52PFL5704D/F7
If your power supply is clicking on and off, first test your power supply by itself using the PON and Ground. This unit is nice because it will list the current draw on the board for each voltage for load testing. If power supply is good, you main board is most likely bad. There are a few surface mount diodes that need to be checked, if your problem is more then just the diode being bad I would recommend just finding a good used main board, time required to repair is much more then the cost of the board.
After getting the main board, leave all other boards disconnected and just connect the main board, power supply should click on and stay on, then one by one connect the other boards leaving the tcon till last.Last edited by jotto; 10-21-2016, 11:24 AM.Comment
