Question about Sharp Aquos LC-42D62U 42 in. LCD HDTV

1 Answer

Sharp Aquos LC-37D44U only shows B&W images from DVD & VHS source

I have just purchased an LC-37D44U LCD TV. I have connected my DVD and VCR to the inputs on the back of the TV. These are typical RCA connectors. When I view the screen and play a movie, it appears as a grainy black and white image. If I plug in the TV to the HDMI port on the back of the DVD, the image is in colour and appears to be crisp. I have changed RCA cables, to no avail. Any idea why this is happening? Thanks for your feedback. Steve

    Hey cjack, thanks for your suggestions. Nothing has worked so far. The reason I was trying to use the RCA jacks as opposed to the HDMI is because when I plug in the HDMI, the sound only comes from my TV, whereas if I use the RCA jacks plugged into my stereo, I have surround sound. Switching my input to HDMI cancels out my AV unit.



    I still have some old VHS tapes, which is why I was using my VCR. I ran the yellow RCA out of the DVD player to the yellow input on the back of the TV. I ran another yellow RCA out of the back of my VCR into another yellow input on the back of the TV. When I select those input channels on the TV, a picture comes up, but it is black and white and grainy, so I don't know what I've done wrong. I had a 32" Philips LCD there before with an identical set-up and it worked fine.



    Thanks for your help. Steve

First thing- why not just use the HDMI instead of standard def cables in the first place? Anyway- If the RCA-video (yellow composite cable) is not producing color, 1 of 2 things may be wrong: 1. You accidentally connected the a/v cables [yellow white and red] to [red green and blue] component inputs or vice versa, or.. 2. Your TV or DVD player is somehow set to the wrong video format. Check the DVD settings for video output format and video connector type. Format should be NTSC, and connector should be composite and/or s-video for the cables you're using.
If this is only happening when connecting the DVD player through the VCR, then check to make sure the same cables connecting the DVD player to the the VCR are also connected to the TV from the VCR.
BTW- if this is just to record DVDs to a VCR, I'll tell you it's not worth it. If your DVD player has an HDMI port, your picture quality will be so much better than if you're watching a VCR copy of one. Your new HDTV will look worse than an old standard def TV. Worse; I'm not kidding.
I hope some of this helps.

    It's quite possible that your TV's composite (a/v) inputs are decoding as component.
    I'll explain:
    -The green "Y" component input (part of Y, Pb, Pr) that can be found on the back of most HDTV's is for luminance, which basically means black and white, or greyscale.
    -A yellow composite input is very similar, but it throws in various shades of color. (hence the term composite)


    Since the jacks are the same (RCA), a TV or a/v receiver can split the use.. It's possible that this is an issue of bad wiring inside your TV and I would return or exchange it. If this is a tested problem with 2 sources, there's no question it's defective.


    If you don't end up sending it in, let me know if you need general advice on diy repair / diagnosis.


    Also, btw- You could just use HDMI from the DVD player, and connect RCAs from your audio line-out jacks on the TV to your surround system. Better yet- use your tv's optical out (Dolby Digital and dts as opposed to stereo), and the problem is solved.

I can't play movies on my tv


Okay, this monitor setup is a little strange. There is an "AVC" component with this monitor that you use to connect everything. There is a 4 cable string (power, s-video, DVI, display port) that connects the AVC unit to the monitor. You must have all external equipment connected to the AVC unit, not to the TV itself. The connections on the TV talk to the AVC unit. I will assume you will be connecting the Blu-ray player via HDMI. HDMI is on input 4 on the back of the AVC unit. hit the input button on the remote or the TV and select input 4. There is a way of customizing the inputs to read out what you have connected to them (ex. DVD, VHS, etc.) to make it easier to use. This should get you signal from your blu-ray

Try different source like VCR, DVD, or satellite to see if it is the source thats bad.  Check to see all your connections are on good and tight.  If still no luck, then your tele is fu.k.d and you got bad LCD crystals or faulty inverter.  Take the thing back to the store for exchange or refund if your within your 30 day window.  Call the manufacturer if your within your 1 year window.

Blank screen with other displays still working


1. By View your DVR, Do you mean you can actually see a picture?
2. By "Switch Channels", are these channels being tuned by the TV Tuner?

Your LCD Panel is OK Since you have a Picture (input display in right corner)
If you can see a picture with your DVR, VCR, DVD or any external source then your TVs Video Processing is OK....if not you will probably need to replace the responsible PWB for this function
If you can see a picture with the external sources and only the TV's Tuner is not showing Video, The PWB responsible for Tuning within the TV should be replaced.

Also, if all problems are associated with only the DVR (I assume this is Sat or Cable), then it is most likely that this device is not functioning properly. Possibly lost signal or deauthorized.

SHARP aquos 1080p HDTV: VCR image flickers when playback


I have the same model TV and the following worked for me. I am using A/V cables attached to Input1 on back of the TV.

On your Sharp TV remote control:
1. Select the Input (1-5) that is attached to your VCR.
2. Go to the menu and select options.
3. Change your color system to NTSC.

This should stop your picture frome flashing on and off.

You still may have a issue with the screen colors. I don't know of a way to address this, other than to make the picture monochrome.

Hope this helps.
