Sharp LC-37D4U 1080i picture problem

I have a Sharp LC-37D4U HD tv that is about a year old. We have been using the tv in conjunction with an hd dvr box from our local cable company (Brighthouse) with no problem. We recently switched to Verizon FiOS service. We have a similar HD DVR box (from Motorola). We are experiencing a problem when switching from non-HD (480i) to HD (1080i) stations. When we move from one to the other, the HD station gets shifted to the right, and the right third of the picture is blurry. Here's the weird part. If we cycle the tv to another input source (e.g., dvd) - even if that input source is on - then cycle back to the HDMI input source, the 1080i signal clears up fine.

    It is not a problem with the tuner box - Verizon tried three different ones. They also swapped our HDMI cable (and kindly gave us the extra).

    There must be some problem with the TV trying to adjust to the 1080i signal from a 480 signal. I am hoping someone might know of some configuration setting that would help with this.

    I have the exact same issue. Our Motorola PVR from shaw worked great with the TV until I moved the TV down stairs, now when we change the channel from SD to HD the picture shifts to the right and goes blurry just as you described. It will clear up if I unplug the TV and plug it back in while still tuned to the HD channel.

Upgraded to Hd and tv started messing up. Double images for first 10 minutes and sometimes tv picture goes off and lines up and down.


Your HDTV is capable of up to 1080P resolution. SDTV (standard def) signals are 480i; EDTV (enhanced def) is 480P; HDTV are 720P, (there is no 720i) 1080i and 1080P. Generally, those modes ending in "P" look better than those ending in "i". 1080i is the highest possible for broadcast TV, but BluRay disks and Directv have 1080P display capabilities.

The double picture you're describing sounds like the TV is set to display only standard or enhanced def signals while the Dish Network box is supplying it with HD signals. You should locate the control for the TV's resolution and make sure it is set to "1080P" and then set the output of your Dish Network set top box to the highest output it offers. Do the same for your BluRay player and any other devices, too.

Once set correctly, you should have a great picture once again. I hope this helps & good luck!

Why can't i see 1080p programs on my directv hd dvr? The test on the hdr says my receiver doesn't receive 1080p. My tv is a Sharp LC-62C42U which is suppose to receive 1080p!


Your DVR can't detect whether your TV can do HD or not. If the message is stating that your receiver (which is your DVR) can't receive 1080P, then you'll need to contact DirecTV for assistance. You may need to replace your DVR.

Could you please tell me if my LC-32GA5E tv can work with sky HD.The manual tells about switching to hd mode,but there seems to be no where to connect hd to the set.The tv is about 5 years old. thanks...


This is an HD ready TV and can definitely be used with Sky HD, but ONLY if the Sky box is connected to the TV with an HDMI cable. It will not work if connected with a scart cable.

So you need 2 things. Firstly, you need to buy an HDMI cable (see picture) if you haven't already got one. Secondly you need to locate the HDMI sockets on your TV and Sky box. The sockets will have the HDMI logo (see picture) next to them.

Please rate my solution if you find this helpful. Thanks.330cd4e.jpg

I have two Sharp Flat Screen TV model # LC-26SB14U. One is hooked up to a regular Dish Network HD receiver. The other is hooked up to a HD DVR receiver. Both are hooked up to the same Phillips DVD player....


if you using the component input on both tvs I will check the settings on the receivers, "HD setup", the difference is because the settings are set one on 480i and the other on 1080i

LCDTV - Picture problem


Do the lines only appear on the Cable box input? It maybe be a problem with your cable. Try to isolate the problem.

Do you see the lines on all sources such as your DVD player as well? If you press the MENU button on the Sharp remote, do the lines go through the menu as well? If yes, it is most likely a TV problem.

A bunch of lines sounds like it is most likely a problem with the connection with the LVDS cable, if not that, then a defective main board.

There isn't really much you can do about it now.
Since the TV is less than a year old, I suggest calling Sharp to locate a local authorized service center.

Blink on Sharp Aquos LC-32D43U


If your using a HD converter box, there is usually a blink when switching from an HD channel to a non HD channel. It is just adjusting from different pictures modes such as changing from a 480i channel/show to a 1080i channel. If this is the case, its perfectly normal.
