No disk error for everything but CDs and Digiview
try to clean the lens of the DVD player you can buy the lens cleaner kit at your local electronics center or at radio shack .just insert the disk cleaner and play it on the machine...read on the cleaner instruction and follow it..if cd cleaning did not work you have to manually clean it with a cotton buds moistened with alcohol this process requires opening of the back cover...try first the 1st procedure and let me know how it goes good luck!

How do you reset the the parental password
Apex TVs use a four digit code to control the v-chip. The override code for many models is 6688. Other sets may not have one, or may have a default code of 1225 instead of an override code.
- To use the override code:
- Hit the MENU key to get to the menus.
- Go down to the SYSTEM menu and hit the right arrow on the remote control.
- Once in the SYSTEM menu, go to PARENTAL GUIDE. It will ask for your code.
- Enter the override code listed above. From here, you can turn on and off different rating restrictions, as well as set a new code.
No matter what the V-chip code is set to, the override code will still work. If you have a blank screen with a red key on the bottom left, simply press the (function or F) button and the mute button at the same time. This will unlock the screen and allow you to view the channel as desired

The tv won't turn on.
TVs and monitors usually incorporate some kind of startup circuit to provide drive to the horizontal output transistor (HOT) until the flyback power supply is running. Yes, TVs and monitors boot just like computers.
There are two typical kinds of symptoms: power on click but nothing else happens or a tick-tick-tick sound indicating cycling of the low voltage (line regulator) but lack of startup horizontal drive.
Check the voltage on the horizontal output transistor (HOT). If no voltage is present, there may be a blown fuse or open fusable resistor - and probably a shorted HOT.
However, if the voltage is normal (or high) - usually 100-150 V, then there is likely a problem with the startup circuit not providing initial base drive to the HOT.
The startup circuits may take several forms:
Discrete multivibrator or other simple transistor circuit to provide base drive to the HOT.
IC which is part of deflection chain powered off of a voltage divider or transformer.
Other type of circuit which operates off of the line which provides some kind of drive to the HOT.
The startup circuit may operate off of the standby power supply or voltage derived from non-isolated input. Be careful - of course, use an isolation transformer whenever working on TVs and especially for power supply problems.
Note that one common way of verifying that this is a startup problem is to inject a 15 kHz signal directly into the HOT base or driver circuit (just for a second or two). If the TV then starts up and continues to run, you know that it is a startup problem. However, this is a risky procedure for both you and the TV.
I have also seen startup circuits that were designed to fail. Turning the TV on and off multiple times would exceed the power ratings of the components in the startup circuit. Some Zenith models have this 'feature'.
When this situation exists, it could be that the circuit is not providing the proper drive or that due to some other circuit condition, the drive is not always sufficient to get the secondary supplies going to the point that the normal circuits take over.
You can still check for bad connections - prod the circuit board with an insulated stick when the problem reoccurs.
