I bought a dcr-sr42 handy cam three years back.. until few days back there was no issues with it suddenly i am not able switch on the handycam? how can i fix it?

hi,
it is not 64 MG, its 64MB, it has a very low memory capacity, this memory card is used for still snaps, you can find the snap button on the cam, this cam will not support much bigger GB memory sticks.

According to Sony this means "Take the camera in for service."

What it usually actually means is that the lens is stuck. Your question doesn't include that information, though.

If the lens is stuck (and you're out of warranty), the best known solution is to smack the camera while it is off. It's a bit scary, but there are many testimonials to it working. I recommend reading a bit at that link.

Check the power adapter that you connect to the wall outlet, with a volt meter at the tip that attaches to the camera, to see if it's producing DC voltage. Verify the value of the voltage by reading the label attached to the adapter - it's usually valued around the voltage of the battery or higher. If you find that the adapter is good, then you have a more complex problem inside the camera - check to see if an indicator lights up when you plug the adapter to the camera. If it doesn't, then the power circuit is bad - not allowing a battery charge. Suggest having it repaired at a shop. Get an estimate first - sometimes the cost of repair will exceed the value of a newer camera. You've had it for three years - looks like you got your moneys worth!

PLease try look on google. On internet you can find almost everything.
Tipe LCD sony DCR-SR42 and see what you can find. Good luck

hard drive is out of alignment. Ive worked on these in the past and flat rate would be around 280 us.

Hi,
To change / reset date and time touch on lcd screen, HOME > SETTINGS > CLOCK / LANG > CLOCK SET and set the date and time.
Above said is mentioned in user manual of DCR-SR42 and you can download it from Sony Support.

Try burning the Video to the Window Movie maker and finish the File as a High Resolution FILE AND THEN try burning the final movie file to the DVD A little long but should work i think

First, I suggest you consult a web buying guide, such as:

The camera you mention has a built in hard drive for media storage.  The main drawbacks are image quality as the picture is highly compressed and you must export your media to your computer.  This feature is either really handy or an inconvenience - it all depends on your preference.  

Take the battery out and turn selection switch to camera and then turn it off. Put the battery back in and its working again.
if that doesn't work try
Try smacking the side of the camera relatively hard with the palm of your hand. Eject the tape and reinsert. You may need to do this a couple of times.

You should make sure the contacts are clean, if not use a damp cloth and wipe of the dusts in the terminals of the battery. This is due to miss allignment.

Thank you...!!!!!
