Question about Televison & Video
If Va and Vs are missing even when the Y-sus board is disconnected from power board then the new board is defective - return it. On the original one the board is shut down (the relays are disconnected) because there is still a short on one of its output lines - replace all the final filtering capacitors, when one has failed the others can't be far behind.
BTW the LG PDP42X3U400 is the brand and model of the plasma screen .

Jason, OK FIRST you MUST get a service manual, (Link supplied below) or you are simply going to waste your time and money. Link below, and then as I tell ALL my students the place to start, the ONLY place to start, is the Power Supply, and here it is simple "Are Your Voltages Correct?" You must examine these voltages and work back along the faulty rail(s) .
You see in any fault we usually have THREE aspects, the fault, the cause, the damage done. ALL these must be solved, or the fault will simply return, at best and still not work at worst.
Use the service manual to guide you especially along the TS flow charts...
Whenever a Cap blows usually there is considerable co-lateral damage, as the enormous current instantaneously draw can damage other parts on the circuit, especially any series components, and stress others, so they may fail soon after & when "put back into service" as it were after the prospective repair.
So you have to find the "Cause" of "Why" the Cap blew? This Cap must be replaced, and any "Other" damage done, this too, must also be found and fixed.
It is always beneficial to understand exactly how the TV, one is servicing, "Boots Up" as it were. Then one can work along the "Path" of powering ON, and find out, either Why, the set itself, is prohibiting the set itself, from powering ON, or, whatever else, is "Stopping" it from doing so.
Above is where to get a service manual, they are worth their weight in gold. Below is a user manual, and below them are Forums to get info from.
