Hi guys, has anyone got the resistor values? Or can read them with a multimeter for me? R19 & R20.

included pics of how it was when I received it, second pic pads Disintegrated Think they used a shovel to solder it but I’ve cleaned up as best as I can and temporarily wired eeprom on pigtails but tv no sign of life then noticed id lost a resistor and the other I can’t get a reading

I happen to be starting the process to replace my EEPROM so made the measurements. Haven't replaced the EEPROM yet. I measure R19 = 3.76 kOhm and R20 = 4.70 kOhm

To close the loop, I messed up. Long story short, I lost an IC pad and got solder onto where it should be so I think I'm hosed.

Tips for beginners like me (I learned soldering only because of this EEPROM problem) so you don't make the same mistake:

• Watch this vid, go to 3:00, notice how there's solder behind the leg (the heel as the video calls it). Remember to get this spot when trying to de-solder the original chip. Also just watch the entire video; it's good info for how to solder on the new chip
  • https://www.youtube.com/watch?v=Nq5ngauITsw
• Don't crank up your solder past the average setting (mine defaults to 350C)
• Don't apply too much heat or for too long on the IC pads to the point they loosen and you lose one of them like me

Long story: Started poking at the legs of the EEPROM with the soldering iron and trying to pull out the chip with tweezers. I was like, I don't see anything moving, so bumped up my iron to its max (500C), still nothing. I was poking all around the leg until I finally saw a leg pop off and realized that spot behind the leg (like in the video which I watched beforehand but didn't put two and two together) what I was missing. I proceeded to get the iron behind each leg, easily popped off the chip, then started cleaning up with an air duster. But I didn't realize somewhere along the way I lost one of the IC pads. When I tried tinning the remaining pads to prep for the new chip, I tried tinning the missing spot and saw a lot of smoke, but no flux. Then I realized that pad was probably important. Whoops.

Edit: I was afraid of accidentally touching other components after reading PCS' post so I was using a super thin tip head for the iron which probably didn't help with heat transfer. So maybe use a bigger tip for removal so it can maybe heat everything up enough that you don't need to worry about the heel, then switch to the thin tip when soldering on the new chip
