dynex dx-l32-10a dead power supply

[slimbarker]

ok so the power supply on my tv is dead
i have 5 other boards that go to other tvs with busted screens
i was thinking maybe i could Make one of the other boards work with my dynex dx-l32-10a tv
it looks simple they both have the pins labeled
it looks as if i could just cut some wires put them to the right pins 12v /pon /gnd /ect...
would this work ? what do you all think? this dynex does not have alot of wires/plugs looks easy
yes i know i could order one but what fun would that be

Re: dynex dx-l32-10a dead power supply

That can be done as long as the power supply has the same power output for the 5V, 12V, 24V, if that is all it uses. I have done on VIZIO and Samsung.
The main will need the 5V, 12V.
The power supply will need PS_ON from the main. The new power supply has the use the same >3v turn on type signal.
The BL_ON line and the Dim line (it can be analog dimming or PWM dimming, you will have to check) from the main board can go directly to the inverter board (they usually route them through the power supply board, it is used as a junction point for cleaner wiring). The 24V will be fed by the power supply.

hmmm i have a cap thats 200v 470uf a x f (PET) i know it would be wise if i keep it in the same uf and go over abit in the volts but think i could use one of these 200v 560uf GU (M) Or 200v 680uf
some seem to think it would be fine to use one but i didnt wont to try it yet with out asking again i am running low on money right now so it couldnt hurt to ask

Where is this cap located at? Is it in the primary side, I never seen the main filter cap rated less than 250VDC since at 120v, the cap will have 165~170VDC on it.

You can use the 560uF. Are you sure it is rated at 200VDC? Your meter has good batteries?
