Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Have a daenyx dv-833 dvd player


Good Morning,

Your connection is very easy so we should not have a problem isolating the problem.
We just have to go slow step by step.

First lets just check the Yellow cable just to be on the safe to side sure it is connected properly on the back of the DVD player and on the Televison.

Second, If the connectionn is secured. Turn the DVD player on, make sure you do not have a disc in the tray then turn the DVD player off.

Make sure the battery on the remote control is a fresh new battery (process of eliminattion).
Hold the remote control in front of the DVD front panel.
Turn the DVD player on with the remote control. Look on the front panel of the DVD player, it should read no disc. Press the Pro.Scan button "once". (Have you notice a flickering on the Television Screen).

If no flickering on the TV screen, press the Pro.Scan button again, ( this will be the second time). Have you notice the flickering?

If not, press the Pro.Scan button again ( third time). Have you notice a flickering on the TV screen?

Did you not notice on the LED of the DVD player if it read anything when you pressed the Pro.Scan button?
Try the above procedure again if your picture did not resume. If the picture resume in black and white, do not press the Pro.Scan button anymore.

Let me know the outcome up to this point.

Thanks,
Mike H.

New Pro Scan LCD TV "flashes"


Some LCD TV's have their own filter to improve image quality, this may be what you are seeing.
see if you can look in the TV's menu for something like that and turn it off.

Hope this helps
thanks for your rating
