After the reclassification, I kind of gave up. Kept scrapping, and putting things where I believe they should go. However, have a few things I need double checked. Well, actually, a bunch of things.

4260 High Peripheral
4262 High Peripheral - Do I remove the two metal tuner boxes? There are 4 ICs on the back, same size as the two on the front beside the Broadcom gold tab BGA.
4264 Gold Finger? High Peripheral? Nothing on back except dozen small MLCCs.
4266 Low Peripheral? - Nothing on back, no gold pins in connectors.
4270 High Peripheral? Nothing on back except the gold pads for the LCD display.
4272 High Peripheral? Very little of mention on back of BD.
4274 & 4275 High Peripheral? Back of board has a bunch of gold pin headers/connectors.
4280 High Peripheral?
4282 High Peripheral? Low or High Telco???

Thanks again,

RFIII

Thank you for taking the time to clear this up.

I’ll be posting more that I think deserve a bump down or up.

Many of the boards I have, I feel, are on the edge and it’s hard for me to tell not knowing some of the tech things about ICs and function.

I’ve tried to play grade master in my head on this board with other people posts, most circuit boards I get right, others, not so much.

Anyway, thanks again ccussins!
