Question about Panasonic Televison & Video
P50UT50 8 blinking lights, attempted restart. Pulled back cover and checked all connections and did a visual check of all boards. Everything looks good. Still get a click on and off, back to 8 flashing lights again. Power supply? SS A SC/SU/SD
Try disconnecting all HDMI cables and plugging the TV into a new wall outlet. If the issue is resolved, it may have been caused by a small power surge from either your wall outlet or one of your source devices.

To eliminate power in as a problem get a small battery backup type UPS. This will eliminate power surge spikes, brown outs and for short time periods blackouts. Yes - these TV's are suseptible to power problems.

Your power supply board is not yet dead, u know basic electronics' and soldering? You have to open the back cover of the television check for dry soldering on the printed circuit board , if found resolder but if not Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
I hope this will help in solving the problem...

The 5vdc standby is working but not the 12 or 24v?
You need to find out if the power supply board is getting PS_ON signal from the main board to turn on the 12/24vdc power supply section.
