R431 1ohm fusable 2 W, , Check D431, C432,, and probably the vert IC. Charlie

R431

D431 is shorted. I take it this a FR104 or NTE552 replacement. Is there any other replacements? Would you also please tell me the vert IC number or something like IC801 so I can find it on the board. Thanks, Jim

Vert chip is IC301, Its probably shorted to, Charlie

any

One last question I hope about this. I pulled the IC301. Is there a way to check any of the 7 pins for shorts with an ohm meter? I tried a few of them & didn't find any shorts. It is very hard to read the IC, but it looks like it is a TA8427K (NTE7158).

Is D431 an FR104? I have a lot of diodes. Is this a special diode or is there a common replacement?

Thanks, Jim (When one lives in the woods of Maine one has to rely on the internet for answers.)

My schematic shows vert IC TDA8427K and the diode a FR105, Dont have a data sheet on the chip, Looks like pin 6 is Vcc, and pin 1 gnd, Its probably not expensive, just replace it, Some caps to check, C303,306,309,311. Good luck, hope this helps Charlie

Charlie, Thanks loads for your help. I have tried to find the NAP site. I must be missing something here. Would you please send me a link or tell me more about NAP.

Thanks, Jim
