My Panasonic DMR-ES30 DVD Recorder / VCR Combo is about 5 years old now its fine on stand by but when i put a dvd or vhs in after about 10 seconds it cuts out completly any solutions on how to fix it thanks

It could be overheating.. Is it fairly consistent at 75 seconds? To test put the unit in the fridge for 30 minutes then quickly connect it up and test. If it is longer then 75 seconds then something is getting to hot. I've put hard drives (especially laptop ones) in the freezer if I need to copy off data but it clicks/stops working at room temp.

I had the same problem with my DMR-E30VS. I tried a disk cleaner, that did not work. I took the cover off cleaned the lens witk a Q-tip and Isopropyl (rubbing) alcohol. It works fine now!

have capaciters in power supply checked if there are bulged capaciters they must be replaced

This is happening because your DVD is NOT all region, you need to change the Code.

Ok check those links out they will help you sort it.

Try a different brand of blank dvd+r or -r. you will find that your dvd machine is fussy on what discs it plays. More exspensive dvd players are fussy with what dvd discs you put in, as cheaper dvd players would virtualy play most types of dvds.

My remote is not working. When I press a button, I get the following message on my unit: U12, U30, SET #, CHK REMOTE #, or RC #. What can I do to fix this? The message displayed means that the remote control and unit are not communicating and the remote needs to be programmed. To program the remote, press and hold the same number that is displaying on the unit and the [ENTER] or [OK] button for more than 2 seconds. For example, if the unit displays “SET 2”, press and hold [2] and [ENTER] or [OK] for more than 2 seconds.

If you combo get activated the progresive scan function you never see the videio only sound you need to deactivate

Hold down the "1" and the "Enter" buttons together for about 10 seconds. This worked for me.

so you want all device connected to each other, right?

it will automatically shut down if there is a heat issue.
