Re: Sharp LC-40LE810UN question



Excuse my ignorance, but what does adjusting the pot actually do? Once I dial it in is it something I can leave alone? Why would I need to 'put it back to the same setting later'?...

Re: Sharp LC-40LE810UN question

So what are your thoughts about cutting away the back case above those optos to improve air flow? Do you think it would be worth it? I mean the set is working great now. So much so Im debating even putting the case back on .

Re: Sharp LC-40LE810UN question

So after taking the back off, I have been running the tv for about 8 hrs now with no back light flicker. Could it be the set was over heating with the back on? I that would explain why it wouldn't flicker right away, but after 5-10 minutes or so. I noticed there are no vent holes above the power board on the back of the case. Why would they do that? Seems that component would be sensitive to heat.

Thanks for your quick response. I plan on taking a look at the boards this weekend. Maybe Ill just replace to opto and go from there. Is there a schematic floating around somewhere? Thanks again !...

Hello,

Some searching via google has led me to this thread. Not to post hijack, but there don't seem to be many threads about this set. I also have the LC-40LE810UN Tv. For a few months now the set will work just fine. Then, after 5 minutes or so the back light will begin to flicker ( much like an old neon tube). Its more of a sporadic flicker ( different intensities) then a steady pulsing.

It happens on every input regardless if it is receiving a video signal or not. When I go to turn the Tv off, the screen ( not...
