Hi,Help
I have a DR-MV1S VHS & DVD combination and it performs superbly but the unit keeps shutting down by its self and looses the Time Date & Year settings.
Pull the plug out from the electric socket then replace the plug and it starts working again for about 8hrs this proceedure can be carried out continualy to keep it working.
Please note: this unit has a energy save select but this is set off.
I have checked the 250V/T2AL fuse on the Primary board and is okay and the cooling fan works okay.
The only thing noted is a very slight blackening/burning around the cooling block element at the center of the primary board.
Thanks Roger.

The block you refer to is likely to be the heatsink for SMPS power switching IC, considering the fact that all of these devices are relatively cheap it would be prudent to purchase one to replace it, as the symptoms you mention are indicative of a heat related failure taking place and this transistor type IC is always the prime suspect.
