Hi, I own a VK 90D, It was satisfactory only until about 2 months back. I started gettin DVD H05 error. It became ok after i disconnected and tried again.. But only today i got error DVD H02 n no dvd...
H02,H05,H07 is an error code in Panasonic home theater system and dvd player which appear after an unsuccessful loading of DVD,CD. This is commonly caused by a faulty lens assembly and the main board. If you want to troubleshoot it yourself, here are some basic steps that may guide you.
that the disc is good.
1.Clean the lens. -
Sometimes because of dust build up and some tiny foreign objects the lens can't read any disc. Try clean the lens by
soft cotton buds. Be careful while doing this.
2.Replace the ribbon - Check
the ribbon connected to the lens from the main board for scratch,
damage. Once it has an open line then of course the lens can't read the
disc. Also try to erase the contact by pencil eraser. If you've done the steps
above and the symptoms still there then the next step requires you a little
knowledge in soldering technique and reading the ohmmeter.
3.Check the motor - Check
the motor that spin the disc with an ohmmeter. You can test it using the
ohmmeter (x1) even it is connected on the lens assembly.Good
motor - reading should be fairly high and it will spin. Bad
motor- reading will drop to low resistance and will not spin.
Hint : 50% of my
repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor
then replace it with a new one. Before replacing the new motor you have to
check the clearance of the disc holder with the old one. The clearance should
be the same as the old because if not the lens will not read the disc if it is
too far or too close.
If you already cleaned the lens, and confirmed that
the ribbon is good as well as the motor then the fault is either on the optical lens and the main board. It is technical to diagnose the fault between the two, I will advice you to send it to panasonic service center to isolate the problem.
Hope it may help you.
Have a nice day!
