Only half the screen displays on DVD player, Wharfedale WDP 1210

We've had the Wharfedale personal DVD player for only 18 months and now on boot-up and play, only the left half of the screen displays correctly. The right half shows just random moving noise lines, split exactly down the middle. Perhaps a display driver chip problem?

All suggestions gratefully received.

    Thanks for the suggestions Sedonix and AvioriX. Twisting the panel did have an effect: the noise signal disappeared and now there's just a static display of feint lines, but still over half the screen. The other half remains unaffected. I've taken the screen casing apart and fiddled with all the ribbon cables but there are no obvious loose connections.

    Trying the video out to a TV is a good idea.
    It is the 1210 model and I have attempted to make the connection to a TV via the yellow socket on the side but it doesn't work. If you can tell me how the external AV connection is set up, I would be grateful.

    Thanks

    I can't yet get to the bottom of the half -screen display problem. It appears from eBay posts that this is not unusual and must therefore be a relatively common component failure, including the screen itself. Does anyone else have a clue about which component though?

  • PeterSpruce Jan 09, 2008

    Thanks for the reply Darklord1. That's the sort of answer I expected. Yes, I understand that these companies consider the items disposble, though £140 ($280) doesn't sound that throwaway to me and I enjoy a challenge! Trying to resolder a surface mount component might be pushing it though.

    Last question then: to find the Video Output module. There's a circuit board on the back of the display inside the lid, rather than inside the body of the device. This would seem to be the most logical place to find the driver.

    The 3 largest ICs are a PVI1005a which Google tells me is a timing controller, a Philips 74HC4053D which is a mux/demux and an unbranded component (the largest) with the number AR01B VL.1.Z which I can't trace. Any further thoughts on what I should be looking for would be welcome.

    Many thanks again.

Hey sorry about your problem, i waited a bit before i posted this in case some other expert might have been able to help you..

Yes you are right, the problem is a common one and it does stem from the Video Output module (ic) yes it can be replaced but these players are cheap it isnt worth the time and hassle tracking down one and then having to replace it. Mostly when this happens the item is considered disposable..Thats why it didnt work when you connected it to the television via the tv output..

If you wish to try to repair it you will have to open your player and get the ic model then google for one, or a substitue(i recomend the substitute as it is cheaper and works better than the original) or you can get it at your local electronics store...

my regards

    Well it should be there, are there any enclosed modules? but it should be there any way it's a bugger to change it so be sure you want to before you actually go through the trouble to google all the ics you find... BTW IT SHOULD BE LABELED ON THE BOARD

Either a problem with the driver or the display panel. Not much you can do about the driver, but more likely its the panel.
Try squeezing the display panel or gently twist it etc. to see if that has any affect on restoring any bad contacts etc.

Is your DVD Player's model WDP1210 or WDP3397B.

If you are using one of these model I will strongly recommend to use AV output to a TV instead of using its LCD screen. If you get full picture at TV, You will isolate the matter that LCD module has problem. If so you can check with a local repair center. If you have any help regarding TV connection via external AV cable please post a follow up message

Hope it will help
Happy New Year
