Iv inserted a blank disc into the DVD recorder but it is coming up with a message "recording error" "can not record on this disc" "E4 54037380"

If its an older recorder it could be the usual problem of a greasy center-disc =
95% OF THE TIMES I could fix a problem like this was by cleaning with rubbing alcohol the rubber ring on the little rotating disc in the center of the drive mechanism. !!!! Because users always stick their index finger into the hole of all the CD'S for inserting a disc into the tray that a tiny amount of grease gets deposited onto the little rotation disc which touches the center of any inserted disc at about half an inch from its center hole. (underneath) When its greasy the discs slide and the inserted discs speed stays uneven and slow.
You must open the drivebox ( after unplugging the power-cable) to see and clean it.
Be careful to not look at it with power "on" because the laser will make you go blind (danger!!!!!!!
I heavily use a Toshiba DVD recorder since 12 years and it is my most reliable and most versatile recorder, while my brand new Sony recorder lasted only 2 years - Others as well had problems with finalizing etc. but in general the cleaning of the little center-disc that pushes from underneath against an inserted DVD to make it spin helps the most.

Try cleaning lens first.

HI,

You can try cleaning the dvd lens with a commercialy available cd/dvd cleaner.

Please check if your blank DVD's are dual layer ( DL ) 8.5 GB disc. If so your player does not support dual layer writing. It will record only on 4.7GB single layer blank discs.

Bulk disc that comes in cylinder case are some time faulty and loses quality because they packed on each other. The lens of the disc are sensitive so if disc is scratch or dirty will get error message "no read". Turn the unit off then unplug ac power cord for more than two minutes then reconnect and try disc again, if issue still exist purchase disc that comes in individual case.

Got the same problem. Happened 2 months after guarantee expired. **** machine. The only good thing is the harddrive and that is made by HITACHI not Panasonic! I go Sony next time. Panasonic quoted £200 plus to fix the problem. I only paid £220 when I bought it new.

Have you tried a disc cleaner yet?

Are you loading to play or to record?
Commercial DVDs should play.
DVDs for recording may not be recognized by your drive. First make sure that the disc is blank. You must insert a blank disc of the proper format: DVD-R or RW, DVD+R or RW. Even with the proper format, some brands may not behave the same way as other brands.

I had that exact same problem. I would record a bunch of dvds with no problems for months and then some and one day it doesn't work. Only this showed up E4 EA03738B. However I've found the solution. Instead of going out and returning the recorder or buying new dvds just purchase a Laser Lense Cleaner. It's a dvd cleaner. Works like a charm.

can only record 2x,4x, and 8x..........not anything beyond 8x it seems....so 1x-16x will not work. Now if I could just get the loading messageto stop on mine.
