Question about Palm Treo 600 Handheld

1 Answer

Treo 600 This guy has two problems, one old and one new. Old problem: I bought this used on ebay and was told there was no sound. Which is true, there is no sound - except when I put it on or take it off the charger. Why does it only work for the charger? I am pretty sure someone has been inside it because it sure looks like a big (dirty) thumbprint on the top half of the inside of the screen. That is not the problem, just a weird thing, which may have something to do with the absence of sound... The more recent problem just started. I was reading an ebook a few days ago and two pixels turned yellow. I did a soft reset and they were still there. Later, I powered the Treo off for a while and when I turned it back on, there were more yellowed out pixels. Now it looks like a bird, at least 20 pixels are bright yellow, almost right in the center of the screen. Does anybody have any idea if this is a permanent problem? I can hotsync, then do a hard reset if I think it's going to help, but am wondering if I would be wasting my time. TIA if you can help me, especially with pixel advice. Roxanne

Re: Treo 600

The problem with the screen pixels turning permanently yellow happened when the touchscreen have had a continuous pressure on it (destroying the licuid cristal display pixels; there is no repair other than touchscreen replacement. Regards, Mauricio

Palm Treo

Sounds like a defective phone...

I'd return it again... mark it to see if it's the same phone being returned to you....(perhaps inside the battery area) then try for
a refund if it happens again... if no refund available... check out

for a defective phone legal settlement offered by Palm

I hope this helps.

My Treo Hard resets repeatedly

Do a simulated-battery-disconnect reset. This is a harder reset then the hard reset. It will simulate disconnecting the battery at a hardware level, so it will completely toast anything on your treo that might be causing the problem. Don't worry it won't hurt your firmware or anything, just all the data will go.

Hold down the BACKSPACE key, and the K key.
While holding it, press and hold the reset button using the reset tool on the stylus.
Hold all three for a few seconds. The treo should turn white, then turn off. If it won't come back on, then you've succeeded.

To get the treo to turn back on, plug it into the charger cable. In a few moments the treo will turn back on, and ask you for your language and regional settings, just like when you first bought it.

If this doesn't fix it, you have a hardware or firmware problem that will be far more difficult to diagnose/fix.

Treo 600 screen

Replace the LCD but I do not think it worth it. You can get a used Treo 600 for less than $50 from Ebay. Do not bother

Palm One Sprint to Cricket Treo 600

This is a problem with the Treo 600's, because the phone is starting to get old and isn't compatible with some gsm providers anymore.

When it is happening, perform a soft reset (push the reset button on the back). Occasionally this helps, but NOT all the time.

Your best bet is to upgrade to a later model treo, like the 680.

Noise problems

This is a common problem, the solution is actually called the "Treo Buzz Fix".

Earlier models of the Treo 600 had an unshielded cable that connects the battery to the main board. This cable causes loud buzzing and interference on the Treo.

If your treo is under warranty (unlikely probably...) then send it back to Palm for replacement.

If not, try the fix. The fix involves disassembling your Treo and wrapping aluminum foil around the offending cable. Here is a guide:

And here is a forum on MyTreo with high resolution pictures of the process, to help you:,54886.msg429525.html#msg429525

This is a somewhat dangerous procedure. It is possible to damage your treo if you aren't careful. Follow all instructions EXTREMELY carefully.

Good luck! And don't break your Treo!

Touch screen not working

The digitizer can sometimes be damaged over time. I would suggest removing the screws from the back of the device, and then reseating the screen ribbon cable.

Replacement Treo won't load my info

I would suggest doing a hard reset on the replacement treo. After that do a hotsync, and choose exhisting user from the drop down menu. This should work.
