no problem.

3 More Notes:

- CAUTION: I have to stress this: You can get a Serious Electrical Shock and hurt or worse!!! So please BE CAREFUL!!!!!.
I used a very flexible silicone oven gloves while testing.

- How do you know if you have the Tab Bond problem??
If you press/squeeze your TV around the border of the LCD and the picture fixes or changes. Most likely you have the tab bond problem.

- When searching Google I had found videos and instructions based on a SONY TV that had this issue. Most likely this is what you will find too.
That's what I used as a guide plus the service manual for my TV.

Yes, good point. I should probably test my tv first to see if that is actually the problem. When you say "press/squeeze your TV around the border of the LCD", do you mean on the lcd panel itself? Or should I press squeeze on the bezel that borders the lcd panel?

The bezel. Not the LCD itself

Mind you this test only worked a few times on my TV and then it never worked again.
I opened up my TV after that since I was out of options and with it open, pressing on the tabs confirmed it for sure.

Great information. Thank you. I am still hoping to try it this weekend despite my wife's protests.

Yep, compressing the bezel fixes the problem for me. So I am shopping for the tab bonds now. How do you know which thickness to get? Do you have to take the tv apart first? Or do you get a variety pack of different thicknesses?

Thanks so much for your input.

It always seems to happen after the warranty expires wink.gif So it looks like the 18 months after March 2 2012 has passes and http://www.samsung.com/us/capacitorsettlement/ is not available.

Friday night, Sat morning and again this am the infamous start up is happening to my LN50A750. Found the receipt, $2800 back in June 2008

It's time to upgrade and then I can fix the capacitor(s) and move it down into the future man cave.

Any kept up with recent Samsungs? Looks like a Sunday AM browsing the AVS TV forums wink.gif

It might be worth it to call them anyway. Maybe they have some unadvertised grace period. The current top of the line is the UN55F8000 for about what you paid. The similarly equipped UN55F7100 is about $1700.

Here is what my power board caps look like.

So how does this model stack up with modern sets?

We've had one since 2008/2009 (LN46A750R1F), hasn't exhibited any problems so far but I'm pretty sure it'll break sooner or later and hopefully we can replace it with a 4K set to last an equally, or longer, amount of time.

Is anyone doing a lot of DLNA viewing with their 'A750 ? I'm in the process of setting up a DLNA server and wanting to know what, if any, limits the A750s have in this regard. (Other than the obvious format limits...)

Aside: we've had our LN52A750 since the fall of 2008 and love it. It will be replaced by a 60 or 65" model in our main viewing area in the near future, but will continue to be used in our house. It will probably move to the master bedroom. However, I've been saying this for over a year now and our 52A750 just keeps chugging along and we keep loving it ! Why stop a good thing ?

Aside II: I actually thought we had an LN52A650... and I've been periodically lurking in that owners thread. However, when I started looking at the DLNA capabilities of our set, I realized it was an 'A750, not an 'A650. Too funny ! I did remember that it had DLNA capability as that was what drove me to buy an 'A750 rather than an 'A650. Funny that its take me 5 years to start using that feature.

Sorry for the babbling... avsforum rocks ! Great thread(s) too.

Edit: very interesting article on setting up DLNA servers for use with the A750s.

I use a WD Live and a old netgear NAS to do DNLA as Samsung products have crappy media players/codexs. Even my new Samsung TV and BluRay (while better then the A750) can't handle the 5.1 DTS mkv files.

Plus due to my AVR only handling HDMI v1.3 I now use optical cables for sound (5.1) for DNLA while the TV speakers are used for live/DVR TV.

Thanks for the heads up. I got DLNA streaming working to my LN40C650. Everything works except that it won't accept MOV files generated on an iPhone. They will need to be transcoded. I haven't tried any high end content yet. I'll pull the cable to the LN52A750 when I get a chance.
