Question about Sony CDX-F7700 CD Player

1 Answer

Main lcd not working.

My player can do everything it should,but there is no display at all. Are there any internal fuses, or does anyone have a circuit diagram. Any help would be great.Have taken the back off the display to see if there are any loose or dry joints but it looks ok.

If the unit is a flip face then suspect the ribbon cable to the main circuit board from the front display. If it isn't a flip face then suspect that the back light lamps are out. If you can see a very very very dim image of the display when it is running then for sure it is a back light problem.

Hi Christopher, where are you located? I have the same TV and am looking for the base stand and original remote if you decide to part it out.

It just wont power up

If you get any power lights, or LCD display, then it is possible that the main processoer could be locked up do to a small power supply. If nothing works, then check for a blown fuse on power supply , or a bad power supply.

Problem on the main display screen on my Nokia 6085

Sounds like a bad lcd flex cable, i fixed mine by ordering the part from an international parts carrier, but if you are not technically inclined to open up your phone and possibly destroy it, i would not recommend it.

CDJ1000 MK2 Powers up but no display & no sound

Had the sam problem... Turn te player upside down, take off the bottom cover and check the semiconductor fuses located near the supply connector on the top of mainboard. The one that is responsible for display is marked as VLOD (-40V). Worked for me :)

AVIC D1 back light/ touch screen not working

The problem is likely FU1821 located on side B of the main system board. the part number is CEK1257 cost is about $10, it is a fast blow 2A fuse. Replacing this yourself will require some fairly good soldering skill, as this is a miniature surface mount component, it doesn't just plug in to the board. I ordered mine from ; but there are several sites that offer this proprietary part, I was able to replace it without incident in about 1 hour using a small soldering iron, forceps (to hold the tiny fuse in place), and a desoldering tool.

Main LCD display doesn't work!

This is a tricky one. There is a very small/thin ribbon cable which connects the LCD display to the main board. If this shifted, or came loose - highly unlikely, but possible - it might explain the issue you are having.

You will have to open it up to see if anything is loose, or not properly connected.

Or, I would suggest taking it to a qualified service center for repair. If the LCD is not damaged, shouldn't be too expensive. If the LCD just burned out, then look to spend about US$120-160 for the repair, including parts.

Face Plate

If this is a "flip face" type of display then you may have a broken lead in the ribbon cable that connects to the main board from the flip face. This is a very common problem. You'll need to replace that ribbon cable.

Sounds to be defective. All white is not normal under any conditions.
