Many times we have TVs that the Power Supply is bad but the rest of the boards status are unknown.(lighting strike) Generally you repair/replace the Power Supply then you can test the Main Board etc..You tell the customer the P.S. is bad and you tell them a certain Price but after you buy the SMPS you find out that the Main Board is bad. To avoid this a universal PS is needed to test the remaining boards.
Making a Univeral Power with 24 vdc for invertors, 12vdc for audio, 5vdc for standby. A high wattage Computer P.S. can be made to fullfil most needs.
Wire jumpers from the Molex to the Main Board etc can be set as needed when needed. Sure its a Pain but at least mostboards can be tested. A bright
LED flashlight can be used to view image on screen if your unable to fire up the inverters.
What wattages / amperage would you guys recomend for each of the desired voltages? Pointers Anyone? Bad Idea?
