Replacing STK Modules in a Panasonic Rear Projection HDTV
If you look up the datasheets for the 392 series, you'd find more differences than power and voltage ratings... Using a similar IC (even if it is the same series) may make it difficult, if not impossible, to converge. It's recommended to change the 2 ICs as a matched pair. Since one already is failing or failed, the other probably isn't too far away.
The resistors mentioned are to bias each output stage for proper deflection and must be within tolerance. They're precision blue flameproofs, so if anything really heated up from a bad IC you'd easily catch any browning / burning. Red is IC7001, blue IC7002, and green is split between the two ICs.
Tha advantage getting a factory supplied or authorized distributor part is you know the LOT NUMBER has been approved by the manufacturer. Generics or unusually cheap originals are often rejects from the manufacturer as being out of tolerance.
The originals are only $29 each directly from Panasonic. Why go through all the effort tearing the thing apart twice to save $30?
Good luck, Mark
