This is not a solution. :(

In Toronto, or indeed anywhere!? I am with you, Pao, the silly parent unit battery (which is a simple wiring case around 2 AAA batteries) can't be purchased anywhere, as far as I can tell. Yet it's so simple, it must be identical to something else out there.

If I find out what, I'll post it here.

I have Philips AVENT DECT baby monitor , the problem is the screen of the parent item was broken i can't see anything but we can hear and talk from it How can i fix the screen again ? Thanks in...

Hi ghadah83,

Doesn't appear there is a fix for a 'broken screen,' however, you may want to visit the Philips Support Site to look further into your issue:

You can also reach Consumer Care by calling 1-800-542-8368. Below is an FAQ that might help, too.

Why does my parent unit not turn on when I place it on the charging base? Answer

Your battery may be flat. It may take up to 1 hour before you can use your baby monitor again. If this happens, we recommend that you fully recharge your battery before use.

Hope this helps. Let me know by rating this solution. Thanks!

What size is the bolt and thread size needed for the tripod mount on the Canon G12 digital camera?

Hi Winterhawk.

I think you'll find all camera tripod mount stuff is termed 1/4-20. That's 0.25 inches diameter, 20 threads per inch.

Obviously you want to make your bolt short so you don't crack the camera case, strip the bolt, or otherwise get into trouble.

Where can i buy a replacement battery for the philips avent baby monitor?

My wife and I have the same monitor in the picture on this FixYa site. The battery pack is basically two AAA nickel metal hydride rechargeable batteries. Remove the old battery pack. Cut the paper that binds the batteries and plastic pieces in place. We bought a pack of rechargeable batteries at Radio Shack. I cut a piece of metal coat hanger about 2/3" long. I then bent it in half forming a squashed U. I placed the piece of hanger in the "top" (w/o holes) piece of plastic and placed the new batteries in the plastic piece (realize that the RH battery needs to have "+" down and the LH battery (-) down). I also slid the bottom piece onto the batteries too. I used some electrical tap to hold the batteries and plastic pieces together (wrapped around the assembly). Snap it will fit slightly tighter than the original, but will work just fine. One could possibly forgo the hanger piece and maybe use some aluminum foil. I figured the coat hanger is a better conductor.

Trying to purchase a replacement parent handset for SCD520?

You can't. I just called Philips and apparently if the parent monitor stops working for whatever reason after the warranty has expired, there is no way to send them off to be repaired and no way to purchase a separate parent model. You are STUCK with buying the whole package again. I have a perfectly good base, but the parent model got into the hands of the child and no longer works. The parent units have to be sold with the base. These parent units are so vulnerable; can't believe there is no way to purchase a replacement. No happy with Philips.

1- The baby unit doesn't work on the mains only 2- The parent unit is on the charger for a day now and still doesn't open

Your issue #1 seems like a power adapter issue. Please swap the sender and receiver adapter and see if anything changes. Mark them with a sticker or felt pen before you do this because they probably are identical.
Your issue #2 seems like you have defective batteries, although I don't understand 'doesn't open'. The receiver uses standard NiMH cells that can be reached through the back battery compartment. You could swap them out and test.
If the set is still within warranty I suggest you take it back. Within the warranty period you usually get a replacement.

I hop this helps.

With kind regards,
Erwin de Raad

Battery in parents monitor won't hold a battery charge. worked for 18 months now just beeps constantly or just turns off.

We had the same exact problem, tried replacing the rechargeable batteries but to no effect. We called Phillips directly and they were very nice and are shipping us a replacement unit (they discontinued this model and I suspect this is a known issue).
