So the LG LCD 32LX1D I have decided not to turn on anymore...

Also, the little red light is not on anymore...I have googled around for answers to this and read a few people saying it might be the power supply.

What do you guys think it may be?

Also, how hard is it to replace the power supply and where can I buy one?

Thanks!

Have you tried the basics yet like the ac cord if it is removeable or checked the wall outlet with a lamp?

Also try LG Tech support to see if there is a reset you can perform.

Are you under warantee? Did you contact LG?
I do not know if it is the power supply but you could do a Google search and see if you could locate one. First I would remove the back and see if there are any bad caps or fuses that are visible. May be a lot cheaper than the complete power supply.

That's an oldie but goodie.

Recall that it had an internal fan that always ran (even when the set was off) for extra cooling.

Your problem is most likely in the power supply circuit..

Replacement power supply boards can be found via google.

Example........

http://allprotvparts.com/product.php?id_product=2011

Since the front panel LED is not on (e.g. its circuit should always be lit and on as long as the set is plugged in and ready to turn the entire set on/off) first check the main fuse. If you zoom in (mouse over) the picture in the above link, it's located top left corner, above the AC cord connector and to the left of a blue rectangular component. It's about 1/4" round and 3/4" long, white with silver colored end caps. If your lucky, it's a commonly available 50 cent part (e.g. even Radio Shack) and appears to be held in end connectors (e.g. easy to remove and replace).

If you have a multimeter pull off the cover and check the main fuse (w/ power cord connected for 120 volt AC on both ends or w/ no power for 0 ohms continuity) and if OK, then the power supply output voltages (values marked near connectors located at lower right on circuit board).

You're very welcome.

Those circuit board shielding enclosures, are typically secured in place with some screws, which when removed, should be easily removable. Occasionally they may also have interlock tabs, but when the screws are removed there should be enough play to see how how to release it and/or first, another cover has to first be removed before the one you want can is free.

Some good news, I found a service manual for your LG 32LXD1.

http://www.scribd.com/doc/50422571/lg-32lx1d-ET-service-manual

It includes a set of troubleshooting flow charts , which like I previously mentioned, begins with the power supply and then progresses through go/no-go modular swap out diagnosis of all subsystems. Additionally, there are block diagrams, exploded mechanical views, wiring diagrams, complete parts lists etc.

If you're lucky, it's the main fuse (which again is cheap, commonly available and a snap to replace).

Lastly, that particular model was prone to developing bad electrolytic capacitors (typically bulging tops and/or leaking). Typically on the power supply board, but could also be on any other board as well. These are also cheap and commonly available parts and a reasonably easy DIY replace (lots of YouTube videos on this)..

Keep us posted on your progress.

I have the same issue. I got the back totally off & removed the fuse. I'm headed to find a replacement but am curious what the electrolytic capacitor looks like in case thats my next step.
