Question about Sony S2 Sports ZS-X3CP CD Boombox

Open Question

The Backlit LCD has intermittent problems

1) The LCD characters will flash intermittently, Some characters are missing, and then they are okay. It occurs any time. When just turning on the unit or when operating it for a while.

2) The orange backlit display has an intermittent 4 vertical bars of less brightness. This may or may not occur when I have problem #1 above.

The Power on Led is always lit up and the audio functions fine. I think it could be one of two issues. The LCD display module, or the powers supply to the display module might have a problem. If I knew which module was used, I could swap it out and see if that solves the problem. If that doesn't work, I would know it wasn't the module, and that would leave either an LCD module power supply problem or a wiring harness/connector problem at either end of the harness.

Does anyone know where I can find the LCD model number and MFG of the LCD display module?

Normally, I would open it up, to find this part, but I have three of them (lots of nice features) and I noticed that the screws that hold the case together are fastened to plastic only. You don't want to open and close the case too many times.

The reason I took the case apart, is that I noticed that two of the boomboxes would easily blow their fuses. After replacing the fuses, I noticed that this boombox was NOT designed for repeated assembly/disassembly to replace the fuse. If I glued the screws or case back I wouldn't be able to open it again with having to cut through the glued parts. So I designed a fix for it. I didn't want to ruin the looks of the boombox, so I made "dummy batteries" which I could use to replace the regular batteries. This boom box EATS UP BATTERIES. So when I am portable, I can use batteries as long as I bring along some replacement spares. When I find a good AC outlet, I remove the REAL batteries and replace with the dummy batteries. It is really not a hassle since I have to take along back up batteries anyway. The dummy batteries are actually double the regular size. They are made of Acrylic plastic and the electrical contacts are soldered to a 22 gauge flat power lead that easily fits through the battery cover. The other end of tghe lead is a polarized D connector that mates with a simlar connector I made for the DC power supply.

BOTTOM LINE , it looks great and works great and I don't have to keep replacing the fuse inside the boombox. As I say, everytime the fuse goes out its a big hassle and difficult to reassemble because of the cheap plastic mounts for the screws. I also replaced the DC wall adapter power supply with a 1 amp regulated switching supply at about the same size and same functionality. Sony needs to redesign the unit so you could easily replace the fuse. Also they need to forget that cheap DC wall adapter PS and replace it with a quality regulated switching supply. I tested the supplied SONY supplies and they are not properly regulated. I also found that the AC outlet spade connectors have a poorly designed connection internal to the wall adapter device. They would have only needed to spend a dollar to fix this!

The Fuse NEVER burns out. I just need to troubleshoot the issue with the LCD module.

My wife teaches music and she loves these boom boxes. They are portable and one MP3 CD can hold hundreds of songs, in that way you don't have to keep replacing normal CD's .

My XM Boombox is also white and it is a Belkin. The folks at Delphi told me the receiver in the boombox is screwed up which over time also screws up the Delphi receiver. Belkin is sending me a new boombox and Delphi is sending me a new Roady XT.

Projection TV no picture flashing horiz arcs across top of screen sound okay

You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

Picture flashes off and on

Hook a spare monitor to the video output usually on the back, if okay! it indicates a loose video cord, or an intermittent display ( replace LCD ) if both screens show the same symptom, it means the video graphics card is defective and is part of the motherboard.

No, you haven't missed anything I can think of, but the fact that it was intermittent, then permanent tells me that somewhere therein lies the answer. I admittedly don't know anything at all about "the orange light control relay", but it seems that if that's the problem it would probably affect both sides. Sorry I can't be more help. . .

I have a 1998 Plymouth voyager and the climate control lights are flashing. I ran a test i found on the internet and got it down to two lights flashing(the ac and the recirculate). I got it to where the...

OK got your message on the other post (About the van) I am assuming that your Voyager is equipped with Automatic Climate Control. Follow the instructions below and you will get a better idea of what is wrong with your system.

1. To enter calibration/diagnostics test, set parking brake. Start and warm engine to normal operating temperature. With engine idling, turn blower switch to high. Turn mode switch to panel. Open all outlets. Move temperature to full cold.
2. Press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (Until ALL LEDs illuminate). All LEDs should illuminate for 5 seconds. Rear wiper and intermittent rear wiper button LEDs will flash alternately during calibration/diagnostics test.
3. After approximately 60 seconds, if only the rear wiper button LED is flashing, calibration is successful and the system is okay. If rear wiper and intermittent rear wiper button LEDs are flashing, Diagnostic Trouble Codes (DTCs) are present. (See "Reading Diagnostic Codes" below)
4. To exit calibration/diagnostics test at any time, press the rear window defogger button, rear wiper button, or cycle the ignition off and then on. Test will automatically terminate 15 minutes after calibration/diagnostics is entered.

Reading Diagnostic Codes
1. Perform calibration/diagnostics test. If a DTC is present after calibration/diagnostics test has been performed, system will flash rear wiper and intermittent rear wiper button LEDs in sequence. Rear wiper represents code level, and intermittent rear wiper button LED represents code value.
2. Each time the rear wash button is depressed, rear wiper button LED wil cycle to the next code level in numeric sequence. After code level 5 is reached, rear wiper button LED will cycle back to code level 1. See table below.

Screen keeps flashing intermittently.

There are a number of possible problems.

When the computer is turned on and you wiggle the LCD back and forth and the video becomes corrupted and then if you wiggle it some more and get it to work correclty then you either have a loose video cable connection or a defective video cable. In some cases the LCD will need to be replaced.

If this is not the case then there is the possibility that the video card is bad.
