GENERAL RF module malfunctioning after R-JTAG installation

[PeteZR1]

Hi guys,

This is 1st time I've suffered an issue like this. I hope someone can help me out, I'm sure it can be fixed very easily but I can't find out how.

Anyway, here's the story: JTAG ALT V2, aud_clamp wire, POST QSB V2 were already installed. I checked the console (Falcon V2 w/dash version 16537) was still booting fine, no issues on that. So I soldered D point to standard C7R112, placed back the motherboard to the metal case for the final testing before writing XeLL into NAND and... RF module green led lights stopped working and so did syncro button embedded in the motherboard.

The thing is console boots if you press the power button in the RF module but no led will shine. And no controllers can be synchronized so there's nothing you can do with the console. Where did I slipped up?

I also tried replacing the RF module with a different one and the issue persists. The RF module doesn't seem to be damaged.

Thanks.

Upload pictures of the install If I remember correctly this has something to do with the little resister/cap ne'er the jtag alt v3 qsb

Check the value of R2P12 - it's a 10K resistor I think.

It's really not that hard..

I see... that's where you solder the top right corner tip of the JTAG ALT V2 QSB.

Resistor checked: 9,51 KOhm.

Done! OP updated

Update: fixed. If I press down the upper tip of JTAG ALT V2 QSB, RF links shine bright. It seems that resistor got loose somehow. Will work it tomorrow with the proper tools (magnifying glass + soldering micro-tips, etc).
