Re: e420vse no standby light



I should clarify my previous post, as I think I gave out misinformation. I was assuming a single series string of LEDs comprise the backlight, but I believe there may be two independent series strings, which are shorted to series/parallel operation when the original mod is performed. It's very important that each series string have its own independent constant current source. Otherwise, if there were two series strings connected in parallel across the same constant-current supply, and one string went open, I think you can see from basic...

Re: e420vse no standby light

I haven't checked back here for a while. I do have the original picture somewhere, but I figured it would be quick and easy to solder onto the bottom of the board where the test points are marked (+24V, GND, VLED). Furthermore, since it's my own TV and I didn't feel like reconfiguring the heat sink and large capacitor, I left the eBay converter board as is. I merely cut out a couple of slits in the back of the TV, using a knife to cut the plastic vertically along the air vent holes, such that the case bends around the large capacitor. I think if you...

Thanks, that's very useful information. In that case, here's a higher voltage version I found on eBay for $14 with free shipping:

Re: e420vse no standby light

As far as the $50 eBay board, I sent the guy a couple of messages, and he replied that:
[LIST=1][*]"this new power supply is only using the old card to connect to power and the leds the old board is nofuntional", and
[*]"yes the the ambient light sensing option will not work with the new power supply."[/LIST]
His power supply looks like it could be identical to one you can buy from China on eBay for $6.50. It looks like he resoldered/reconfigured it slightly so that its height is reduced in order to fit inside...
