Question about Sharp Aquos LC-45GD4U 45 in. LCD HDTV

1 Answer

1080p ** Longer Available, problems switching to 1080i.

Sorry the story is a bit long. About a year ago I **ticed that my Motorola cable box (1080i) which was plugged into the DVI port on the TV wouldn't work. The TV would show the picture for about 4 seconds and then tell me "** signal detected". I played around with power, input selection, etc and eventually it would work again. Strange thing is that my Xbox 360 was able to output 1080p fine at the time though old style component connectors. Eventually about 4 months ago the DVI completely failed with the cable box - ** way to get it to work. I thought it was the cable box and switched to component for it and everything worked and I forgot about it. About 3 months ago my Xbox failed to work at 1080p and **w only functions at 1080i. At the same time I have problems switching from 720p (or less) up to 1080i using the Motorola cable box (but from 1080i to 720p works without a problem). I have to select a blank input and then back to the Motorola input before it will show the picture properly (otherwise it looks like it's a copy protected signal). I purchased a PS3 a few weeks ago and an expensive HDMI cable. The PS3 doesn't detect a 1080p signal (I've tried all the tricks about settings in the PS3 with ** avail). A guy on a**ther site said the TV needs a firware upgrade. I don't believe this as it used to work fine for over 3 years. I'm capable of replacing the boards myself but need to k**w if there is truely a hardware failure and if so which board is likely the issue. I'm leaning toward the main unit board, KD006, but thinking it might also be the digital board, XD001. Does anyone have any suggestions other than call a repair guy? There is ** Sharp authorized repair in my area and Sharp wants me to ship the set to a center. For the costs of shipping to and from and the parts, I could buy a new tv! Plus I'd be without it for up to 12 weeks. Someone has to have an idea. Thanks in advance.

I'm a sharp servicing technician and since both the component and hdmi have problems, Im leaning towards the Main board also. If it was the digital board, only the hdmi would have a problem.

If you do end up replacing the main board. ONce youve installed it, check to see if it has the latest firmware version. New boards from Sharp are supposed to be preloaded with the latest firmware, but sometimes they are not.

A firmware upgrade is possible because it deals with this sort of DVI/HDMI compatibility issue. It would be the easiest and cheapest fix. Enter the Service Menu to check what version you have. The latest is version 1.31

good luck.

Will not display 1080p from cable company. i have a hd box hooked up


Most cable HD-boxes output either 720p or 1080i, not 1080p.
Set your TV to 1080i or 720p.
Set the HD box to the same resolution.

Have a DX-L40-10A, the TV no longer brodcasts in 1080p on our HD channels, only in 720p maximum. Have contacted our cable provider, Charter Communications and they say the issue is the TV. Is there a way...


Which cable box do you have? Is it Motorola or Scientific Atlanta?

If it is Motorola then press turn the power off then press the menu button. There should be a setting for ypbr output and use the left and or right arrow button on the remote to change this setting to 1080i

Thanks,

TV set always starts up indicating 420p. How do I get it to 1080?I have Bell expressvu HD


is your cable or sat in HD(720p, 1080i, 1080p) over the air broadcast in the usa is in digital so it should start at the highest res available in your area

next are you using HDMI or composite for your cable or sat going into your tv if not your not going to get higher than 420p because A/V and S-video do NOT support HD

check your cable/sat box is it HD(high def) or SD(standard def) if SD going through cattv/attn in your only going to get 420p

now for changing the resolution its automatic it goes to the highest setting on its own

you can control the resolution through your cable/sat box, blue ray/hddvd player and other HD devices connected to the tv through the options menus of those devices BUT only when connected through

HDMI(supports 720p, 1080i, 1080p)
composite(supports 420p, 420i, 720p)
A/v and S-video(supports 420p)
cat tv/attn in(supports 420p, 720p, 1080i, 1080p) only supports what the tuner will do

i=50hz
p=60hz

My Insignia hd 1080p tv is only receiving at 720p. I am using HDMI cables and a telus hd tv box. How do I get it to receive at the full 1080p?


I hate to be the one to break this to you, but there is very little 1080p content available to be viewed on your television. Telus TV outputs only 720p or 1080i video, so you are getting the best available picture already. The exception is Blu-ray, where almost all content is played at 1080p if you use an HDMI cable.

My tv is Samsung TOCa750. How do I set it up for 1080p and 120Hz?


Resolution such as 1080p,1080i etc. set by your source of the signal, for example, if your cable box set to 720p that is what you going to get from the TV. Cable box is ont capable of resolution more then 1080i because there is nobody broadcast in 1080p yet. Only way you can get 1080p is BD player, upconverting dvd player or media player. 120 Hz is just a frame rate convertor - takes stendard 60Hz and doubles number of frames to 120. So, you will see 120 frames per second instead of 60.

How do I get from 480 to 1080p on my tv? I have an HD box on my vizio 42 inch tv but my channels are still showing 480?


1080P is a quality you'll only get with a blue ray quality video. Therefore, you won't get 1080P on cable tv. If your cable provider has HD channels available, you'll be able to get 720 or 1080i quality video (on those channels only). For the best quality, make sure you are using an HDMI cable. Just be sure your cable box supports an HDMI output. Your Vizio definately supports that type of input. If you have a PS3 or alternative blue ray player, you'll be able to watch 1080P.

1080P video via HDMI generates awful interference


Your Plasma's native resolution is 720P. Go into the Blu Ray's output setup. you can choose 480p 480i 720p 1080i and 1080p. Set it for 720p that should clear up the issue.You may have to run Component directly to the TV since you only have 1 HDMI input and you can run Digital coax or optical to your AV receiver for audio. On a 50" TV the difference between 720p and 1080p using "GOOD" cables cannot be seen by the human eye. Above 50, yes it is noticeable.
Hope this helps.

PS3 can not perform 1080P.


TV will automatically convert signal to 1080i ; it's all in the tvs chip.
There's not much difference really! If your not seeing any image and show no signal in that input;you will have to reset your PS3 and it should work...hope that helps!
