I have a curtis lcd1922a flat screen tv and all it does is green light flashes. No picture no nothing. Can you help.

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.

open and check for swolen capacitors and replace

I think i may need a new power cord for my 32 inch curtis. where would i be able to get a replacement?

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

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

power supply problem, or bad inverter, need to be replaced.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_92c86cbc79e9b552

The ballast transformer of the cold cathode on your monitor is overheating.. Replace this..If the monitor is on and keeps on changing from white screen to black. The cold cathode light is almost up. Replace this one too.

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...
