Re: Logik LOG32lw782

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

yes

[multimeter]

Re: Logik LOG32lw782

those are good then

Re: Logik LOG32lw782

thinking it might be easier to buy a new psu that can do returns lol

[multimeter]

Re: Logik LOG32lw782

have you done checks as in post #82 ?

[joehezzer]

Re: Logik LOG32lw782

pl801 both red wires read about 0.60/0.70 ohms the two black ones 00.0 on yellow block with set turned off.

pl802 all red wires read wire 1.03 and rising all black ones on this block 0.00, slightly orange wire 1.24, blue wire 3.41.

Re: Logik LOG32lw782

pl805 first two red wires 1.73, 3 yellow wires 0.73, 4 black wires 0.00, two yellow wires 0.30, last red wire 0.56. is that right

your getting 1.73 reading on the red wires?,is that ohm reading?,with psu out of tv and on your bench,nothing connected to it?

yes 1.73 on pl805 block the first two red wires 1.73 ohms. psu is connected all wires except mains plug

disconnect that connector with the red wires,and test that again,as it stands that is showing a short

ok disconnected block in pic and tested pin on psu was still getting 1.73ohm

Re: Logik LOG32lw782

so are you testing with the connector disconnected and touching the red probe meter pin on to the psu pin direct and still getting that reading i have a 17pw15-9 psu sat in front of me as we spaek same connections on mine as yours and i get no reading on those pins at all.

yes

Re: Logik LOG32lw782

is that meter supposed to be just on 200 and not 20k

[vinceroger69]

Re: Logik LOG32lw782

i have just done the same test 1 reading on 200 ohms my board is 100% good as i have just recapped it and put it back in the set and it works fine.
did you say you have 2 power boards i wonder what the other one reads?

[vinceroger69]

Re: Logik LOG32lw782

lets see what multimeter or tom etc says regarding your readings but the board does look faulty imo.

Re: Logik LOG32lw782

yes 200.

you have a short on that rail,you need to trace back ,and test those components,that is quire nearly a dead short there,there could be a diode along the way,mosfet ,you need to check them

[joehezzer]

ok just wondered ok changing dmm to 200ohm not 20k, i am getting 1 is that a better reading

[vinceroger69]

Re: Logik LOG32lw782

on 200 ohms i get 1 as well

shorting your probes together gives you what? a "1" or "0.00" ?

Re: Logik LOG32lw782

0.03 connecting probes together, connecting to board i get a 1
