Magnavox 27MS343S
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 "Jim" wrote in message news:4hc8h.2627$mM1.2305@trndny08... One last question I hope about this. I pulled the IC301.
