Hello

Firstly, you can transfer your picture using bluetooth. Activate bluetooth on Apple I mac phone and send the picture from Sanyo 3810.

Secondly, You can remove the memory card on the Sanyo 3810 and insert it on Apple I mac phone.

Photos in the Sanyo phone can not be displayed on tv it can only be displayed on computer using your USB ports and connecting the laptop and the Sanyo phone with the USB code.

Take care,

When I close my Sanyo SCP-7050 cell phone, the screen will go blank for a few seconds. Then, it will come back on and state that it's "Looking for service..." and then "Entering Sprint service area." After that, everything is back to normal.

It doesn't happen all the time but just enough to be frustrating.

Screen sound bad, or intermittent connection inside. You can find disassembly instructions on the net. Search with phone model and disassemble. Remove and reattach all cables in case one is lose or contact dirty.

It seems like this problem would have to be with the picture tube itself, although I have never run into this symptom in over 30 years of servicing TV's. If the CRT is still in warranty I would get it checked out. Otherwise it probably not be worth repairing. If you end up replacing the set, check out the Toshiba 24" model. I have had good luck with that model in the past.
