Re: SHARP LC-46DG2U Vertical Lines on menus / block pattern on display

Ahh...ok thank you. The strange thing is that since I did the heat up, the TV has been functioning normally for a few hours, though apparently I shouldn't expect any long term results. I do see there are main boards for sale on eBay for around $80 or less which apparently come from units with shattered screens.

Totally lost me. Again, I'm a complete novice. I don't know what a cap is. I'm not sure which is the heatsink and I don't know how you tell what esr is or what that even means....

Re: SHARP LC-46DG2U Vertical Lines on menus / block pattern on display

Ok, thanks Vince. But what area should I be heating? Like I said, I don't see a conventional heatsink as far as how I know they're supposed to look.

Re: SHARP LC-46DG2U Vertical Lines on menus / block pattern on display

Hey, just as a follow up, wanted to let you know that the early testing of this has seemed to work so far. It was a real bugger getting that inside shield to come off as the screws were incredibly tight, but managed. There does seem to actually be a secondary shield on that main board. I didn't really see a traditional looking heatsink, unless it's under that second shield (see pic), which doesn't simply have screws to detach it.

Therefore, I just hit that area with the lower level of heat on a...

Got that.... thanks for the tips, fellas!

Re: SHARP LC-46DG2U Vertical Lines on menus / block pattern on display

Thanks again. So let me ask another incredibly novice question. Since I see a lot of repair suggestions involving placing the unit face down when doing repairs, that would not apply here I assume. The other would be more so for soldering and the like of course, correct?

Re: SHARP LC-46DG2U Vertical Lines on menus / block pattern on display

Thanks for such a quick reply. I'd like to say I knew what you're talking about, but have absolutely no idea. I don't know where these components are and how one safely heats them.

Hi all. Thanks to the owner/mods for allowing thread creation so quickly on this site. I hope to learn a lot.

This unit is coming up on 8 years old. The symptoms, seen in the pics, started up a few weeks ago. They appear soon after turning the set on. They occur on any input, HDMI or component. It seemed initially it was only horizontal on the display, but I may not have been looking closely enough. It does not seem to affect anything if I push on the input ports (if that means anything to anyone).

From what I've read I possibly could get away with just a capacitor swap...

Re: New Members - please post your introductions here

Hi all.... I'm Gordo and found this site via the avsforum.com site (thanks budwich if that's your name on here too!).

I generally know my way around the software of a PC pretty well and enjoy still and video editing (and long walks on the beach!.... I keed, I keed!) I'm not that handy with the hardward electronics end of things but did build my own PC from a kit, though it was fairly elementary. I do like to pick the brains of the tech friends I have.

I'm specifically here because of the latest symptoms...
