Protection appears across screen and wont let me record

“Denon AV 1801 doesnt appear to power up even though the screen comes up.”Screen lit up means CPU does not have any problem. Did it power up within 5 second? If yes, find out which protection is now working. “Also there is no sound output” May be DSP problem. Remember to download AVR1801 service manual to check protection and DSP problem.

I assume you are trying to record from a VCR tape to a dvd? It could be the copyright protection causing this issue. A little more information would be a great help. What are you trying to record? VCR Tapes. Are these home movies or are they retail movies. Macrovision prevents recording. If you are trying to record a television show, it could be the digital rights protection. do you have it connected to satellite or cable.

1) Have you successfully recorded video on this unit previously?

2) Do you have a memory card in the camera?

a) If not, it doesn't take long to fill the 128MB internal memory, which would prevent further recording.

b) If you have a memory card installed, you may want to check how much available memory there remains.

try camera menu (change some settings )

you are prohibited from recording on thips tape. This is because the red tab on the side of the tape that faces you when you are inserting the tape inside the camera has been put in 'SAVE' position . to be able to record o the tape you need to use your fingernail to slide the red tab to the 'REC' position.

Ive extracted the following article for you from wilkepedia to help you understand this issue:
Tape and recording protection
The write-protect switch (right) prevents accidental erasure. .
To prevent the recording on the tape from being erased, there is a small write-protect tab that can be moved to one of two positions, labeled "REC" and "SAVE". Comparing the sliding tab to a door, the tape is in the "REC" position is when the "door" is open and the "SAVE" position when it is closed. (Not all tape cases have markings for this information!) The tape can only be recorded on (or recorded over) when this tab is in the "REC" position. This is an improved version of the VHS write-protect tab, which prevents erasure after it has been (permanently) broken off.

check the memory card that you've inserted on your camcorder. tilt the protection tab of the memory card to unprotect it.

There you go. Thats a good way to get the problem solved.

Hi,

If you are trying to record to a tape and the display shows "Protection", you must slide the protection tab at the top of the tape to the "Rec" position.

my canon zr 200 in playback is fine but when i turn it on to record i have multi colored bars on screen and wont record

Most likely cause could be a blown power amp IC. The part number is STK402-040.
