The self check function is not working - u61 keeps appearing on the display screen when self check function is trying to work.
Self-check function is normally carried out from the power supply across the motherboard, and so on, to determine the overall 'condition' of all the relative circuitry in the unit (much like a PC does when booting up and loading the system). However, when it is interrupted by an error, such as U61, you can bet a connected device to the motherboard is the prime suspect. In this model, it would be somewhere in the DVD drive area (or the drive itself). If this drive is making clunking grinding noises just before the error code appears, then the drive is defective, and should be replaced, not repaired.
In some cases, it can also be the digital controller sub-panel (located on a platform under the DVD drive in this model and other models in this series; this little board contains the CPU and RAM chips, plus other parts, including many which are surface-mounted on the copper side - the DVD drive is connected to it via ribbon cables - then this board is connected via a couple more connectors/plugs to the motherboard, hence the terms 'sub-panel' or 'control module'). Either way, unless you are aware of the likely cost(s) involved (being a new DVD-RAM drive if required as well as a replacement digital controller PCB (as mentioned above)), it could prove expensive and/or uneconomical to repair.
I would not discount the power supply in this situation either; eliminate all likely possible avenues of issue to be sure, starting with electrolytic capacitors, and going from there.
I happen to possess 2 of these combo units, and neither performs a self-check on startup, although I have had the 'NoREAD' error once or twice.
Nevertheless, if you have any doubts you can always take your combo to an authorised Panasonic service centre, hopefully they can assess the problems, provide you a reasonable (if not free) quote on the likely 'fix-up' costs involved, which you can then make a decision afterwards as to whether or not it is worth restoring to former glory. Up to you.
