Unit ran fine since feb 2005 but now is locked in "PLEASE WAIT" or U99 error. Panasonic says send back but found good info except for wrong unit at www.dxcc.com/dmr-e85h.htm Does anybody have any similar experience but with my model. Also how can I learn the secret commands. Some of those at the above site worked on my unit but it's still unusable. I am an electronic tech so can solder and work at component levels.
The U99 error is a data issue during the booting up proceedure at start up. I cannot start the unit. I've read about this and the person who wrote the article in my first post was able to resolve the issue but his was a DRM-E85H I was hoping to find somebody with experience on my model, the DMR-T6070P I never had any problems with discs slipping or dirty lasers. This problem is different but thanks any way for your suggestion.
I have an older model HDD in stock and will compare it with the one in the unit to try doing that. Per Panasonic U99 is called "Hang Up" and is a communication error between the Main Processor and the Timer Processor. I thought these boards functioned independently from the HDD but will try if mine will work. Thanks for ideas. Hope our exchanges will help others because it seems that a lot of people have suffered from this problem.
