I'm desperate, i have runing every forums looking for a solution, but I'm more convinced than ever that my case is machine malfunction.
Since three weeks ago, that the K200D only flashes battery symbol in LCD.
I never had the same problems that i read about battery performance, with the machine taking only a few dozen photos with good batteries.
Normally i can take around 300 to 600 photos with some Energyzer +2500mah rechargeables, and i got around 1100 pinctures with the Energyzer Lithium that came with the machine when i bought it.
I've tried numerous times on / off, remove battery, put back, put everything in nanual, autofocus off, Stabilizer off, nothing works. The batteries are charged, I've tried with some new Energyzer Alkaline, and now I've tried with some Energyzer Lithium, this ones should give enough power to the camera.
I have already connected the machine to a 6.5V transformer that is not Pentax, but without success.
The only thing that the machine does, besides the battery flashing on the lcd, is an internal click when you put the batteries, but I think it happened before.
All this happened to me before, but only for a day.
My hopes are vanishing...
