How to unlock the parental control on Advent Q1435A

No signal symptom. Check and replace its tuner. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

If you are saying no red: The model indicated here Recoton Advent Advent Q1435A TV is a 14 inch set.

first it may be cheaper to replace than repair--That said if no red look to the small circuit board at end of picture tube (it plugs onto the tube).

It will have either individual output transistors or a single IC.

What (if only one color missing) I would look at is the bottom side which faces to the rear---a circle of solder connections--possible one is broken--there will be one for each red, green, and blue--not always easy to see but if any of the solder connections look cracked or even broken loose-----

I have a insignia tv need code to operate control it's a deluxe universal remote

Check www.remotecentral.com for the manual and codes.

hold the display button for 3 seconds and it should unlock the parental control.

The screen is probably shot, or something is wrong inside the unit. Send it in for warranty, return it to the store if not very old, or replace it if it's too old.

I'm having the exact same problem with the same TV right now, would love to know how you fixed it as I've lost the user guide. Thanks

I need the code for Advent Q1435 to use on my Direct TV remote.
