Something is wrong with this board!!!!

[kgavionics]

Hi guys
i'm trying to repair a panasonic Plasma tv model TC-P50G20 which doesn't turn on the power light flashes 4 times.Downloaded the tv manual and they said that's a protection mode due to something wrong with the power board.i removed the back cover, plugged my the tv to take some voltage measurement and when i plugged the AC cable i saw something burning in the SD board.I took the SD board apart and it turned out that a resistor is missing, probably the resistor melted ( see pic1).all seems normal,till i went to the components replacement list: the missing resistor is R423 (22OHM resistor), but i found that the other two resistors R422 and R421 are labled 7R5 like you can see in pic2.
7R5 is 7.5 ohm resistor as far as know, but in the part list the value of R422 is 24.9 kohm and R421 is 13.3 Kohm
this tv i got from someone who said that it has never been opened before.
i want to know why there's mismatch between the actual board and the part list?
Can some one explain to me what's going on?
thanks in advance

Do you know why those R burned up? Without investigating the purpose of them you can not know if the manual mismatch is reasonable or not. Moreover if you just bilnd replace them there is the risk they will die again.

you're right zucca, after test i found some shorted out mosfet.By the way,  i found the picture of an original board on internet ( see picture attached), and it looks that the R423 is not present in the board, so in my case the burn out resistor was  R422.
The only problem i have now, that between the actual board and manual there's a big mismatch.for instance the burned out resistor is referenced 16402 in the manual, but referenced R422 in the actual board.
by the way,i have the right manual and i'm 100% sure about it.
