Sharp LC-45 OFFICIAL OWNERS THREAD Part 2: FAQ/ Clayface issue... - Page 43

Many thanks for your reply. I'm guessing you have to set everything to 1080i on the ps3 though, right?
But sounds like the deinterlacer does a fine job, so maybe no need to upgrade to 1080p yet...

Necroing this thread for a slightly oddball question.

On my second GX6U - picked up off of Craigslist for mom - I recently got a great deal for a VP50 to try to both improve PQ a bit for her fav that's still in 480i (The Daily Show) and also to hook up a PS3 that I got her for Bluray.

Now, mom doesn't have a stereo system, nor am I going to shell out money for a 5.1 system for her, so my plan was to use the AVC box as the amp and continue running sound through the GX6U's speakers. They're not great - my experience trying to run them as the center channel in the middle of some Maggies lasted all of 5 minutes before I couldn't take it anymore - but that said they're not awful.

Here's the thing though - since the VP50 doesn't have analog output for audio, I'm curious how others have solved this issue, since I know there are others out there who kept running the box for the speakers. The good news is that hooking up the AVC via one of the VP50 HDMI inputs appears to solve any potential HDCP issues and lets me continue to use the volume control and other features (backlight!); the bad is that as best I've got two fairly meh options when it comes to rerouting audio:

1. Split the HDMI output of the VP50 and run a second cable back to the AVC
2. Use a Gefen to convert the optical to analog

Issue with #1 is that I'm not sure I can get the lipsync right to reflect the time it takes to process audio on the AVC, as although I haven't messed with lipsync options of the VP50 yet, the delay seemed pretty noticeable. (And would I have to use a powered 1x2 adapter for the split or has anyone tried going passive?) Issue with #2 is that I found a post by their tech support that the Gefen adapter can't handle 5.1 audio, although they're soon to be releasing one that can.

Any experience with this by anyone out there?

Sell the Vp50 and buy a VP30. Use the extra money to buy the speakers.

Considering I got the VP50 for cheaper than for what VP30s sell typically, nope.

I figured out a better idea - a separate Dolby 5.1 decoder - but I'm honestly curious if anyone came up with a solution for this ex-that.

In that case, here is my opinion:

There is no easy answer. I got rid of my AVC box entirely. Your #1 option seems way too complicated. The problem with correcting the lip sync on the VP series is that the delay needs to be the same for all channels and sources. I dont bother with mine as some channels is right on and others have a delay. So by correcting the delay, I will be causing a problem with the good channels.

Option #2 seems more simple but then you will have to wait for the 5.1 conversion package from Geffen.

Option #3 - Just cave in and buy her a surround system.

The only downside with VP50 is that I dont believe they will support it any longer (with firmware upgrades) as the VP50pro seems to be their baby now. Better be happy with what it offers.

My LC45GX6U has white screen!! Service came yesterday (7-15-08) and said my AVC box is bad. Will need to replace or repair. First problem ever with this set since I bought it new 8-15-05!! All I did on Friday 7-11-08 @ 3:45pm was turn of the unit using the power button on top the panel, and leave the house. My wife calls at 6:20pm and tells me about the white screen. I have been controlling this TV with RS232 and IR since I bought it, and have used this power button on top of the panel before. Why did this happen, anybody have this happen to them,and if so what happened and how was it corrected? Anybody still post here?

My Tv Is Fixed!

Tech Came By(7/23/08) With A New Avc Box And Everything Is Working No White Screen!!
Thanks To The One Guy Who Read The Post, I Still Would Like To Know If Anyone Has Had This Problem Of A White Screen And What Lead To It.

Just curious...was it under warranty or did you have to pay for the new AVC? If you had to pay, what does a new one cost?
thanks,
Murray

So has anyone had any success with driving the GX6U with an AVR? I'm particularly interested in the Onkyo 875, 905, and new 906.

I have the Onkyo 805 and you can't get the on screen display from the onkyo to the GX6U (if bypassing the AVC box). Once I set it up it wasn't a big deal but since the panel will not take anything directly other than 1080p you have to be sure everything is being scaled up. So the other models you mentioned might do 1080p upscaling but you best be sure first.

Couldn't you feed your s-video or composite monitor out to one of your s-video or composite video in's, have it upscaled to 1080p then send the upscaled signal to the GX6U via the HDMI monitor out for setup purposes and viewing other receiver information?

I have a new VP between the panel and the AV unit - everything looks great but it takes a little setting up to get it to work after turning it on. For those of you with similar setups is their a "trick" to getting things to work from power on every time, i.e. turn on VP first, wait 5 sec, etc.

No, the Onkyo 805 doesn't upscale to 1080p, they didn't really mention that in the literature at the time when i bought it.

After only a short 1.5 years since I bought my Key Digital iSync Pro video scaler, I finally took it out of the box and hooked it up to my LC-45GX6U panel. After a few problems with the wrong output settings (had YPbCr instead of RGB or auto selected) I got a picture to display on my panel.

A couple of things that I found.
1) The panel shuts off after 10-15 seconds if the other 2 cables besides the DVI is connected to the AVC.

2) I was able to use a DVI Detective hooked up to the AVC's DVI port and keep the other 2 cables going from the AVC to the panel without the panel shutting down.

I haven't had much time to play with the calibration settings yet, but the inital picture is kind of grainy and washed out looking (don't know of a better way of describing it). Could this be due to the max backlight issue that has been reported earlier when the AVC box is taken out of the equation? If it is just a matter of the factors I have control over through the iSync (brightness, contrast, saturation, etc.) I will spend some time this weekend adjusting these settings, but don't want to put a lot of time in it if this sounds like a backlight issue.

Since I am able to keep the display on using the DVI Detective, I assume that I still have backlight control by keeping the other 2 cables attached to the AVC & Panel -- is that correct. If so, can I just adjust the backlight control for one of the inputs of the AVC, always select that input and have the panel retain the backlight settings for that input?

thanks,
Murray

I've owned a Sharp Aquos LC-45GX6U for almost exactly 3 years to the day. A few weeks ago the thing thing just stopped powering on. The monitor turns on and lights up, showing a gray screen, but the AVC box (TU-GD10U-T) won't turn on--so no signal goes to the TV.

People on this forum claim to be able to send a signal directly to the DVI input on the back of the monitor, but I don't see how. It didn't work for me. The screen stayed gray when inputting from all devices except my Blu-Ray player--there was still, however, no picture. Input from the Blu Ray player resulted in a small scrambled image showing in the top left corner (about 8" x 8") of the TV. I had seen the movie that was playing so I could recognize the very scrambled image, but it was not at all watchable. If it were a movie I had never seen before it would look like nothing but mixed up lines.

Anyway, after trying mutiple tries, and several days, of trying to get the TV to come back on, I bought a new TV and moved this one to my bedroom. I continued to play with it until saying, let me try the original set up one more time. Viola...I don't know what was different, but it worked. And it worked reliably. I left it like that for days. Then I got off my lazy butt and decided, that since the TV worked and I already have a new 52" in the living room, I should set this one up a little more neatly. After disconnecting power, wires, etc. then setting everything back up nice and neat....:-( sad to report the same problem came back. TV lights up, but AVC box won't power on. All I hear is "CLICK" ....."click". Then I stare at the beautiful gray screen.

Suggestions? Taco: who did you call for repair/replacement of the AVC box? And what did it run you if you don't mind my asking?

Any suggestions? Your help is much appreciated!

Called Sharp today and they were of absolutely no help. For a TV just barely 3 years old, this seems a little ridiculous. Thank goodness I bought a Samsung to replace it. Sharp does sell replacement AVC boxes, but they charge $995 for them. At that price I can get a new 1080p TV! Silly. Just silly!

If someone can tell me how to bypass the AVC box and use the monitor directly, that would actually work for me too. It just doesn't work for me--not plug and play. Is there a trick/secret to this?

I had mine hooked up to my computer a while ago. You just need to make sure you are sending it 1920x1080p settings at 60Hz. This is the only resolution that it will accept. For other sources that are not 1080p, you could use a video scaler that will convert your source signal to 1080p. I have had success doing this with a Key Digital video scaler. I am sure that you could find a used video scaler on eBay for less than the $995 that sharp wants for theirs. You could also keep your eye on eBay and check to see if there are any AVC's for sale. Every few months it seems that one pops up there.

Good luck.

Murray

Aww man, I'll try this. Thanks so much! Will post an update to let you know if it works or not.

Is there any way to use the audio input on the back of the TV? Or will I need external speakers when taking this route?

Hey Murray, I bought a Gefen VGA to DVI Scaler Plus box and it worked. Resolution on my PC needs to be set to 1024 x 768, but other than that...no hassles. Thanks a lot! Now I guess I'll got get a new PC with a built in TV tuner for my desk so I can use the monitor for everything.... Anyone have experience using a PC with built in Tuner?

I am sure that the audio cord could be modified if you knew which wires are carrying the left/right audio, but I am pretty sure that there is no pre-made adapter and you would have to make a DIY modification. Glad you got your panel working once more.

Hey,

Not sure if anyone will ever see this, but here goes:

I've had my LC-45GX6U for over 3 years and have loved it since the day it arrived. It's been almost entirely trouble free until now. When my Comcast DVR is connected via HDMI (and DVI as well I believe) the picture will cut out periodically (for a few seconds every few minutes). Audio continues to work even when the picture does not. When the DVR is connected via component it seems to work fine. I know I'm out of luck with regards to warranty, and a local repair guy told me that the problem is likely that the TV's software is old (HDMI was very new when this TV came out) and not fully compatible with HDMI (or perhaps HDCP). His advice was to get a component video switcher (since I have more than two component devices). This is a cheap option, but then I'm basically forgoing any future digital connectivity.

Does anyone have any other advice? I know I could in theory replace the AVC box with something like the DVDO edge and an separate audio receiver, but that seems to involve lots of little compromises like losing brightness control, etc.

Anyway, the TV still looks great and I'm still happy with the purchase, I just wish I could reliably connect my DVR digitally...

Does anybody know what bit panels the LC-45 uses (8-bit, 10-bit), etc?

Thanks

I'm expecting my AVC box to bomb in the near future, as it started overheating and shutting off when sitting on top of my HTPC (which it never used to do).

I currently use my LC-45 with a Gefen DVI switch and I toggle between my AVC box and my PC. I always have to turn the display on with the avc as the source, initially, then I can switch to the PC with the DVI switch.

I browse the 'net at 1024x768 (so I can read the text), but I watch movies through the PC's DVD player, record/watch TV with Windows Media Center and also play games -- all at 1080p.

Knowing that I will have to replace this AVC unit (which is consequently also taking a cablecard at the moment), can someone please list alternative units that would work as a go-between for the PC? I am specifically looking for DVI in and out and I want to be able to turn the panel on and use the PC as the source without the AVC unit.

I noticed a quality loss on another Aquos I have when adapting DVI to HDMI from the PC, so if I can avoid that I would be thrilled.

I hope I explained this correctly. Thanks, in advance, for any advice!

I have it in the vertical stand, at the moment, away from everything and it is working well. I just know that it's days are numbered and am trying to anticipate finding another solution BEFORE I'm stuck without my awesome display. I really love this thing!

It's not cheap, but you might consider using the DVDO Edge as a replacement. You'd need to convert the HDMI out to DVI. Good luck!

What is it about the AVC box that allows the display to turn on and stay on -- I know I can't do it with just my PC, even with the DVI detective? I guess if I know how that works, then I can find an alternative.... ?
