Wierd LED when charging?

Okay so recently i encountered a problem on my One V. When i plug it in for charging the light is orange for a few seconds and then it begins blinking the LED. not only that, the color changes too from orange to green and back to orange and so on. its not that big of a deal but what pisses me off is that the phone isn't charging... but DRAINING when plugged in. i tried : 4 a/c addapters ,4 plugs and 3 USB cables. same thing every damn time. any fix to this?
Have you tries flashing other Kernels...If not try it...If this doesn't work then get you phone replaced.!.!

What could be the problem pls? Sudden red blinking light...

Hello guys,
Wondering if you know what this issue could be. Basically, I had not used my xperia play for a few years and I wanted to try a few emulators on it now, so I tried to start it up and it worked twice, I could see the Sony logo and then it went onto a white screen (this is why I changed it on the 1st place and I think it'll need a Flex cable).
The problem is that after those 2 times, the mobile was vibrating when I tried to turn it on but nothing on the screen at all (not even the previous Sony logo I saw). I managed to plug the charger, get a static red light, which then turned orange and after like 10h that I checked again it was green.
I trid to start it up again, but still nothing. What's happening now is that as soon as I disconnected the charger when it was with the green light, when I connect the charger again it has a blinking red light that doesn't disappear (I've left it charging for hours but same light still there).
I tried to connect it to the computer, but I get a message of USB device not recognized, tried to udpate drivers for Xperia Play or someone mentioned some Zeus drivers, but still the computer cannot see it.
I was wondering if it'd be worth buying a new battery as well to see if this fixes the problem? What do you think? As mentioned, before the problem, I just saw it booting up correctly a couple of times and I didn't do anything afterwards...
Cheers
I could be wrong, but if the phone wasn't used for a few years, I would suspect your battery is part of the problem. I remember that I had an orange light and the phone wouldn't boot for me either when my battery was bad. I bought Hyperion batteries and the phone has worked great since.
As far as the phone not being recognized... I'm not sure. I would probably try uninstalling all Sony related drivers, then reboot the computer and reinstall them. Maybe see if you can get Flashtool to recognize the phone in Flashmode or FastBoot as well.
Do you think the computer should recognized the phone (xperia play in this case) even with a battery problem? for example, if the phone is switched off and the battery removed? (or does it need to be turned on?)
The phone definitely needs to be turned on to be recognized... either booted up normally or on fastboot mode, Flashmode, etc.... I can't remember if it will work in Flashmode or fastboot without the battery inserted... but I'm thinking it won't. I'm at work, but if I get some time to try it out tonight, I will report back.
If you could have a quick look at some point (no rush), out of curiosity, to see what happens if you try to connect it to the PC without the battery? I was thinking that it might be recognizable (as there's power coming in from the USB cable), however in my case I keep on getting the red blinking light when I plug it to the PC without the battery as well and I get the message saying that the device has not been recognized.
I've ordered a new battery anyway to see how it goes. I will learn something from the experience whether it finally ends up working or not...
Cheers!

Ok. I did some testing and you definitely need to have the battery inserted for fastboot mode or Flashmode to work. There is no response from the phone or the computer when only plugged in with the usb cable (and no battery) while holding back button or search button.
If your battery is bad (like we suspect after not using the phone for a few years)....then hopefully you'll be able to get into Flashmode/FastBoot again once you get your new battery.
As far as the screen turning white... it sounds like you're probably correct with thinking something could be wrong with your slider /flex cable.... but that's hard to know for sure. When my friend's flex cable was bad, it started out with lines through the screen and eventually had a strange textured grey/white appearance when the cable finally went completely out.
Just quick update for future reference in case someone faces a similar problem.
The red blinking light when trying to charge the mobile with an old battery was caused by the battery being faulty after a long period without use. I ordered a new one and as soon as I plugged it in to the charger, the light became orange (rather than red) and a little while later green.
Even with the battery charged, I had the problem that I couldn't see anything at all on the screen. The mobile vibrated when being switched on but then just a black screen. It turned out to be the 'flex cable'. It was totally knackered. Replaced with a new one and all working as well now.
Cheers!!

[Q] Charging problems

Hei,
since recent I had no problems with my Xperia Arc S. But recently I had the problems that sometimes if the battery goes below 20% the phone switches off randomly, and recharging was impossible. Replacing the battery did not change the problem.
When I plug the charger in, the following scheme happens: Either the LED gets instant green, or it blinks red. Regardless of the LED while charged, when putting it off the charger, the LED switches off. When trying to switch it on again, the LED just blinks red. How can I fix that?
Thanks!
The LED blinks red whenever your battery is to low, the green one usually means it is charging, so either you got a problem with your software, or either your battery is dead,you could even try an other charger , since I had problems with my USB-port with some cables
