Question about Cyberhome CH-LDV 700B Portable DVD Player

1 Answer

7" LCD Video screen Ribbon Cable - need replacement - can anyone help?

After only about 12 uses, our CH-LDV 700 started showing a loss in vertical and horizontal hold on the video. After checking that the video to a TV screen was OK and only the 7" internal video was affected. I disassembled the unit and found that the ribbon cable that passes through the hinge had broken due to it's folded and captive design were it would rest on the support post. I've temporarily jumped the broken trace and the unit works as designed. Does anyone know were to locate a replacement cable? Or know of a manufacture for this cable? Thank you and have a great day, John

Re: 7" LCD Video screen Ribbon Cable - need replacement -...

You may be able to find a comparable cable on some other brand, but Cyberhome seems to be defunct. An alternative is to find another unit of the same make and brand and scavenge what you need...accordianman

The cyberhome no picture when playing a dvd on the ch-ldv 712

Sometimes portable DVD players allow you to switch to a secondary TV for playback. When this happens it disables the primary screen on the portable DVD player.

Thats usually the culprit as to why that happens.

If you have that feature on your portable DVD player you should check it out.

That ribbon cable is a tedious repair, and the best you can hope for is that you are a fairly good tech yourself, or to send it off for repair...accordianman

Cyberhome DVD Player Ch-LDV 700B

Sound like you have a back-light issue with the LCD. Not sure what kind of technology they use to back-light the LCD, but on all LCD monitors and TV's they use CCFL. Cold Cathode Fluorescent Lamps can burn out or can get damaged. Not sure if the DVD player uses them or not, you just need to open the back panel of the LCD and see what they use. Also CCFLs need an Inverter circuit to convert the DC current to AC current. If it uses CCFLs than it can only be 2 things the Lamps or the Inverter circuit. Check the lamps, if they look dark at the ends, than most likely a bad lamp. If the lamps look fine, than you will need a volt meter to check the status of the inverter.
