Hi there, I'm having the same problem with my TAVL1R, it's giving me error code 3/4 and the supposed 'Sony Techs' are not being helpful. I will appreciate any related recommendations that could help me resolve this issue. Thanks.

The problem is with one of the capacitors, Sony can replace it for you at a cost of $80. This error can come, if we click photos continuosly, the capacitor may get heated up. We need to give a gap of 3 to 4 seconds. Time to be given for the flash to get recharged after a click.
Just give a call at Sony help line. 800.222.SONY, they will replace the capacitor.

If its worth the cost, go for the repair, or you can use the device without flash by disabling the flash. At setup just disable the flash and this error wont show up again.

Main code 95 : Digital signal process system error and communication error with ICs
7 : STANDBY-OFF mode
4 : Capstan motor/FG
4 : FG cannot be detected.
