RCA RLVD3282a No Led Backlight

Re: RCA RLVD3282a No Led Backlight

No need to. It turns out there are test points already there I was just testing wrong since I thought they were in parallel. There is a test point between each led, you can see one above the writing in the second pic of post 6.

I've replaced the led and dome and now waiting for the glue to dry. Not really the same but the alternative was to have a darker spot. Six of one half dozen of another. I'll post a pic of the working backlight later today.

Here's a pic of it working. In person the replaced led has a slight yellow tint where the others are white. I would expect it to be less noticeable when assembled. The replaced led is on the left in the close-up.

Nice! I doubt that you will notice it.
Is that the same LEDs you sent to me?

Yes same one. I hope it doesn't run too hot for the dome ? I don't know if I could adequately test that without the screen being back on to trap the heat.

BTW, may be running the BACKLIGHTS level at around 80% may help prolong the LED's life.

Good idea, bud.

This backlight doesn't run hot at all so I don't think heat will be a problem.

Re: RCA RLVD3282a No Led Backlight

Hi I need some help as have the same problem as described here for a RCA LED model RLDEDV4255. I found a burnt led and did a bridge between the 2 test points and got the LED working only for a bit until another LED burnt.

Now I would like to try what mmartell did replacing the led and dome but no idea how to do it. Any help will appreciated.

I am attaching a picture of the bridge I did. Sorry it is upside down.

Thanks for your help.

Norcal715 posted a great video on how he removed the dome and replaced the led. It's an LG set, but it looks like you can apply the same ideas to your set.
