Ответ на "Screen has no time displayed"Hi Kim Daughters iH8 had same problem. No schematics available and not a viable repair job for economical reasons. However I found the fault and it is a manufacturing one that is likely to be the cause of many of such no display /operation failures. In my case power was there to the keyboard and charging the iPod. Internal supply rails appeared OK, other than the secondary rails driven by the Toshiba TC9349A Microprocessor (a SMD device mounted just behind the display and covered by RF shield ) and you guessed it this also feeds the display. I found that if I placed my oscilloscope on the Micro Clock, it started to work, however would stop shortly after it was removed. When I removed the 75Khz Crystal there was rubber glue that had gone hard and as is common, become conductive and detuned the crystal. Removing the gunk from across the leads fixed the problem. I will attempt to post pictures somewhere on the web as I don't appear to be able to add them here. If you need instructions on how to check send me...
