This is the ribbon connecting the 2 boards on the right side of the panel.

You will be removing the side drivers. Not the ones on the bottom! Don't remove those. Wrong area. The right side is the area. Not right bottom.

Oh got ya... These? There's 8 on the right side that are only connected to the back of the panel. And just kinda hang over the side.

And I think I read to clean off back of panel where these were connected with alcohol, is that correct? I've read so much on here its all kind of running together.

OK so this particular panel does not have driver boards attached to those ribbons. Shouldn't be a big deal. You can try removing them since this is the side that's causing the issue.

This is the right side (side) of the panel correct?

Not necessary to use rubbing alcohol.

Before you do this can you post a picture of the tcon board?

So if it does not have the driver board like the others, does that mean it might work for me?

Well that is definitely a Sharp tcon board. It is a little bit different panel however it should hinder the same results as the models with the driver boards on the sides.

Note that this is an irreversible process and I bear no responsibility if it doesn't work right. But considering the Present condition of the panel it's either make it or break it at this point anyhow.

Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

This is the only thing I know to do. I hold no one responsible but myself. Like I said earlier, the picture was fine until I replaced the backlight strips and put it back together. The picture was dim in a lot of different spots and after pulling the backlights I found most were out. Not sure exactly what happened but hopefully this will fix the problems. Thanks for the help.

Keep us posted. Good luck

Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

before you go too far... you can unclamp the "interconnecting flex cable" that you show going between the two boards on the bottom on the half in question.... leave all other cables connected. This may help show more about what's up with the panel.

Are you talking about this one? On the bottom right side? And should I do it before removing the drivers on the side?

**budwich** · 02-14-2018, 02:28 PM

Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

yes to those flex interconnect cable... no don't remove the side drivers at this time... this allows you to isolate the far side of the set and check what the result is WITHOUT DOING ANYTHING ELSE at this time. Since these flex interconnect cables are unclampable, they can be put back without any issue as oppose to removing the side drivers which is a one time event. Depending on what the resulting image is, may tell you more about what you are up against... before going any further.

Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

I just noticed that one of the eight driver tabs on the right side is missing. Evidently it came off in my initial dismantling. It's on the bottom right side.

**budwich** · 02-14-2018, 03:05 PM

Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

well that's your problem. That means you have no choice but to remove the other ones on that side and cross your fingers.

**sawilson** · 02-14-2018, 03:16 PM

Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

It didn't just come off, it tore and part is still on the panel.didn't think it did anything so I didn't mention it.

Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

now you different... :-( too bad as you likely had a "perfect set". IF you are lucky and the removal of the rest of the side tabs is good / clean, your tv should be OK.
good luck.

Ok.. Agreed that's your problem. You cannot have any damage to any ribbon driver on the panel of it will cause problems. At least you didn't damage any of the source drivers.

Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

So I should go ahead and pull the other seven off completely?
