Re: Logik LOG32lw782

pin 12 +5v

pin 10,11 +3.3v

pin 1,2,3 +5v
are you seeing any voltage on those?

pin 12 +5v yes 5.2v

pin 10,11 +3.3v yes 3.3v

pin 1,2,3 +5v nothing this is on pl805 the one marked in blue

Re: Logik LOG32lw782

check all your +v pins to cold ground,you want to be seeing hundreds of kohm,a few ohms will indicate a short on that rail.

ive had those 2 diodes just to the right on that big yellow transformer(the ones with the metal support upstands) fail a couple of times,maybee worth a check,just pull one leg and diode test them

Re: Logik LOG32lw782

You have pressed the little side on/off button right? Without that, standby light is OFF.

will diodes now and report back

a toshiba regza caught me out on that one!,large switch to the left,but standby button on the other side of the tv!!,it worked when i pressed it

it most likely wouldnt have when they filled them with crappy oem boards further on..

Re: Logik LOG32lw782

ok just checked diodes on ohm the readings danced around the on the one just said 1

did you pull one leg of each diode and test and read both ways??part number of the diodes?

had a couple like that with rocker switches lol, i cannot see any separate switches anywhere

yes disconnected from circuit board. diode stps sl60 chn729. changes leads around and got 1.97ohms

Re: Logik LOG32lw782

use the diode test on yr dmm,forward voltage should be around 0.19v thats at 5.26ma test voltage

and they are shottky diodes,so you will have a little reverse when testing

forward voltage read nothing reverse nothing again not sure if i am doing it right, could be that they are shorted

Re: Logik LOG32lw782

can you post a picture of your multimeter so we can make sure you have it on the right settings etc.

[joehezzer]

Re: Logik LOG32lw782

yep

[vinceroger69]

Re: Logik LOG32lw782

diode is the one before 200 ohms try testing them on that setting

[joehezzer]

Re: Logik LOG32lw782

diode is the one before 200 ohms try testing them on that setting

yep tried that got nothing just stays on 1 rather than 00.0 when both probes are connected

[multimeter]

Re: Logik LOG32lw782

yep tried that got nothing just stays on 1 rather than 00.0 when both probes are connected

if your getting that when reversing probes,your diodes are open,00.0 on ohm setting will indicate a dead short

[joehezzer]

Re: Logik LOG32lw782

ok reversed it and got 160 on diode setting.

when i try on ohms i get 1 reverse it and get 1.98ohms

[multimeter]

Re: Logik LOG32lw782

ok reversed it and got 160 ohms

right,so dmm set to diode test one way your getting a reading reverse your not?

[joehezzer]

Re: Logik LOG32lw782

getting a reading on reverse and nothing when i put red lead on the cathode end

[joehezzer]

Re: Logik LOG32lw782

sorry my fault again been reading diode wrong lol dmm set on diode i get 164, reverse it i get 1. sorry guys my mistake
