Those four resistors all checked out good. The only thing off the board now is the TPS chip and a cap PC5302. With the battery plugged in testing to ground those two solder pads you highlighted in the picture, the meter just kept flashing from 1.5 to 2.5 volts, back and forth.... -
Dammit, I measured S TO G AGAIN ON 6204 and got 1.7 meg. (I tripled checked this time). My bad. Thanks for the hot air setting too btw....Leave a comment:

Here are the resistance values you requested. The voltage values to follow After your directions from post Odd power issue related to bad caps? above.
PQ6204 - S-D .7 MEG S-G 6 OHMS D-G .5MEG PQ6201 - S-D OL S-G 4MEG D-G OL
D1-SID2 - 2.2 MEG S1D2 - G1 3.2 MEG S2-SID2 8MEG S2-G2 1.6MEG S1D2 -G2 3MEG
PR6209,6211,6210 &6215, ALL WITH IN SPECS!

Will do. Clarification: When you want me to measure resistance, this is with no power connected to the board right?
When you want me to measure voltages, is this with just the charger plugged in, with the charger and the battery plugged in or just the battery?
I want the info I give you to be as accurate as I canLast edited by bogart219; Yesterday, 05:56 AM.Leave a comment:

Hello. Removed TPS chip. from schematic checked all pads (that had to do with voltage), to ground and found NONE shorted. With battery plugged in only, measuring to ground, J4 and J5 still 0 volts.
PJ6201 & PJ6206 LEFT SIDE STILL FLASHING RIGHT SIDE 0 VOLTS.
Still a problem with downloading attachments I believe.Leave a comment:

I replaced that TPS chip but its very possible I shorted it out with my half ass soldering I Thought I had soldered but bump it a few days later and move it moved around. I will put the old one back in as there was probably nothing wrong with it( you or mon2 didn't tell me to replace it), I did that on my own....Leave a comment:

WITH JUST THE CHARGER PLUGGED IN: PJ6201 NO VOLTAGE TO GROUND. PJ6206 , LEFT SIDE 2.5 VOLTS RIGHT SIDE HALF A VOLT. J4 AND J5 NO VOLTAGE AND NOT FLASHING.
WITH JUST THE BATTERY PLUGGED IN : PJ6201 & PJ6206 BOTH RIGHT SIDE FLASHING, LEFT SIDE 0 VOLTS. J4 & J5 0 VOLTS AND NOT FLASHING.
If I check a capacitor and get a reading to ground on both sides, doesn't that mean the cap is shorted? Thank YouLeave a comment:

Still no power there on either one. On both One side flashes overload and the other side has .5 & .1 volts going down like a cap is discharging or something. What kind of pads are those?
I see the picture posting is still not working

Hi. when I check the voltages to ground on PJ6201 and PJ6206 with just the battery, the meter just flashes back and forth between 1 and 3 volts approx. No steady reading....Leave a comment:

Pics still not working for me. Will try again in the morning, thanks....Leave a comment:

Reflowed the TPS chip and reattached the cap, still getting flashing meter like before.
With batt & charger plugged in. On the BG chip, ( PU5301) was getting 11.7, 3.2 and 1.4 volts on a number of pins. RE4501 & RE4505 , NOT ON THE BOARD....Leave a comment:

PC6230 = 3.28 VOLTS
PC6231 = CAN'T FIND (MISSING) ?...Leave a comment:

I got to have something touching somewhere , where its not supposed to touch by getting that flashing OL reading on my meter where I should be reading 3 and 5 volts. I started looking for solder blobs again. I was checking the components that I put down and found that TPS chip I replaced , I was actually able to push it around with my tweezers1, wtf, It wasn't soldered down properly.a cap right next to it came off too! Let me get this straighten out (hopefully). Also hoping this was the cause of the flashing readings! I will let you know! Thanks!Leave a comment:

Good morning. with just the charger plugged in, 0 volts on both. with the charger and the battery plugged in, I get that rapid flashing OL symbol on the meter on both. Its seems like something is getting two sources of power at once or something....

+3VL at PC6205, near PU6219 0 VOLTS
+3VALW at PJ6201 0 VOLTS
+5VL at PC6204 (one side is GND, the other is +5VL) 0 VOLTS THESE ARE WITH THE CHARGER ONLY PLUGGED IN.
+5VALW at PJ6206 0 VOLTS
+3VALW_PCH at J2 CAN'T FIND!
+1.8VALW at PJ7912 0 VOLTS
+3VS at J5 0 VOLTS
+5VS at J4 0 VOLTS
+3VL at PC6205, near PU6219 3.28 VOLTS
+3VALW at PJ6201 THE METER JUST RAPIDLY FLASHES!
+5VL at PC6204 (one side is GND, the other is +5VL) ...Leave a comment:

Mich, once more thank you for your help. i just hope that i didn't fruck something upI will do those test and post

I'm not reading any voltage anywhere on or near the power button.

When I started out trouble shooting this board here, with the battery plugged in I was getting 20 volts on my usb-c tester. Now I only get 5.2 volts with or without the battery plugged in. Do you think it would be a good time for some voltage injection and scan with the thermal camera?Leave a comment:

Thank Mods for getting this post back up. I got the parts in and installed I'm ready to continue my quest. Now where was I?Leave a comment:
