Screen goes black after 2 seconds

power pack probably has blown capacitors on it. need replacement of those and the tv should be fine.

I would replace the entire inverter board. Picking and choosing will cost more.

Call Dish and ask them is there any firmware you need for your tv....they should provide it for you.

You may need new inverters, CCFL's, or your power supply is not [providing regulated 24 volts...

We have these Akai boards in stock if you need them.....

One of these boards are causing this problem, we have them in stock if you need them. the tv is programmed to shut down if all circuits are not functioning properly.

This is a mean problem, and I feel for anyone who has it.

This can be caused by a bad power board, a bad main board or a lcd LCD panel.

An authorized repair shop would be able to substitute the main and power boards to find the source of the fault, but you don't have that luxury.

Unless you want to risk paying for an expensive part you don't need, I would suggest you take it to an Akai repair shop.

Air 2 is the source it's looking at for a signal - - where is the signal plugged into? and are you able to change the input or source to look at another?

This is an indication that one of the components in the screen control sections has a thermal instability problem. This canusually be found using a product called cool mist which is a component cooling spray. This lowers the compenent temperature and allows you to see which component has the problem. Also you may want to if you are able try to use a voltmenter and a schematic to trace the problem down once you know which component is giving you the problem.
