I have a Curtis flat screen tv that when you turn it on after about a minute the picture starts going on and off repeatedly.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

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.

Dark tv picture

It will be best to contact either the authorized service center for Curtis, or any experienced service technician. Sounds like a back-light inverter fault. Gopakumar Gopalan Google

TV is not coming on

If I understand your problem correctly, it sounds like the unit is not coming on... If this is correct, then replace the 3 capacitors on the output side of the power supply. There are 2@1000uF @25V and 1 smaller one which is 220uF@25V.
I think the part number on the board is marked as WX-15/19/20Power-01...
This worked on a 19 curtis LCDVD191
Hope this helps...
