Re: wrong ps for treo
Your first gonna need a schematic unless a factory service tech can tell ya if theres a zener diode on the power input or where the internal regulator is located. A zener diode is like a voltage stopper and wont let the voltage go any higher tyhen what the diodes ratings for and can take some punishment but will over heat and fail. Hopfully you didnt burn up any PC traces Good Luck

Your unit being stuck in standby mode is an indication that its having a power problem. Remove its plug from the wall and fix it back into the wall, then turn it on again. If its still stuck in safe mode, then the power supply board in the unit is the cause of the problem.
The power supply board might be defective and maybe that's why the unit won't power up. Its receiving power but it cannot transfer the current to the necessary part of the unit because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the unit might not come on.
To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter in order to test the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.
Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.
I wish you the best of luck.....
There must have been some power surge which must have damaged the power supply unit. Some of the new Sony systems have class D amplifier which uses Switch Mode Power Supply. They are very light and efficient but are very sensitive to spikes and surges unlike good old heavy transformers. Since its only a few day old just return it and get your replacement. Remember to plug all Audio and Video equipment in future through a surge protector . Sometimes known as spike guard.
You could have damaged the player totally by this accidental plug in. The problem is that unless there is a protection of a reverse diode to short off the ipod can be finished off.
So open the ipod and take a test if there is any fusible link tha thas opened , then link it to short, if a diode has short remove and replace but if the mP is not working even with an established power into the player then we have a serious fault and can be irrepairable but with a high cost.
Mine did that and I just futzed around with it (take the battery out, then put the unit in the charger). Stuff like that. Also watch the power supply for the charger! Mine read 5V ok until I plugged it in. Then it dropped to 4V. I bought a whole new radio before I figgured it out. (I'm using an old PC PS for the 5V now.)
Hold down the stop button for 15 seconds to try and force the unit to power off. Then leave it for a couple of days whilst the charge dissipates. Look at the charger you used and compare its output voltage to that of the Archos one.
If the voltage is higher than the Archos one it is quite likely that the charge circuit and or the battery may have been adversely affected.
If the unit still misbehaves after a few days changes are you will need to have it looked at. If it is in warranty, try a claim, but do not mention you used the wrong charger!
no as long the player is not damage you can still match the voltage because the 12v is not going to turn on or work properly on the h320 because the voltage is not right. Unless if you have a closer voltage like 4.5v or 5.2 v it will be good it will work.
Example:When i bought my pda it did not come with adapter so they gave me an alternative adapter is supposed to 5v but they gave me 6v to try out first it work then second try i turn my pda using the ac it have problem with voltage because is too high than 5v. The next thing i did is buy another adapter good thing i found closer to 5v which is 5.2v which is it work.....now by pda work..properly and i can charge it properly too.. well it takes sometime to look around the shop until it can be found the right adapter....
Well i used the USB to AC adapter 5.2v...it work great... for mp3 player like h320,pda........
Hold down the <down arrow> button while plugging in the USB cable and the Treo 15 will automatically start in the Hard Disk mode. Then, you can add or remove software as if it were a hard drive. Works like a charm!! (Be sure to have the power cord attached.)
It just had a bad current that went through it the player shouldn't fry, check the battery voltage see if its still got the original voltage if not it will be under its capacity.
Rejuvenate the battery and use the right power supply this time.
If its still under warranty take the player and its original charger back to where you got the player from and they might swap it out.
