Power problem are cause by many reasons, i.e Power supply circuit, Lamp driver circuit and most often the TV detects an error cause by power surges. To protect TV from further damage most LCD TV have protection circuit built internally. If this is the reason of your LCD TV not powering On, an error data must be reset back to zero.
To change data you will need to access the service mode and change the value of lamp error code to zero (0). Entering service mode requires a trained TV technician. Changing data can cause more problem to your television. If you are not qualified to service your television, please do not go to service menu codes. Moreover below are the process, pls do so at your own risk.
* Unplug the TV * Press and hold the {VOL -} + {CH+} buttons located on LCD TV unit (not in remote control) Note: If above didn't work, alternately use (VOL -) + (TV/AV input) buttons located on LCD TV unit (not in remote control) * While holding the above buttons, plug in the TV. * The TV will turn on with the "K" or "K123" appears om screen. * Use {CH+} {CH -} buttons to go and display the service menu. Note: If above didn't work, alternately use (VOL -) + (CH -) buttons. * Search for "LAMP ERROR menu" from the displayed service menu by using "up or Down cursor" from remote control, or alternatively use "CH - or CH+ to select "LAMP ERROR" * change it to zero (0) value, using {VOL+} or (VOL -) on remote control. * Turn the set off to exit the Service Menu.

Could be a possible error except if the cable you have connected is having this code come up. so make sure if the display code is on the TV and not onthe signal.
If so at the time of the error, make sure the possibility of any external prompts is occuring at this time .
remove the main board and fix back all connectors, test again.
Make sure the mP is working with with the right voltage and no prompts are possible. .. even an external IR from a remote.

how to resolve K123 Text on screen. Volume control takes only three modes 0-50-100.It is the problem with all the other controls too.

push vol-, input, and power, at same time. keep push until tv start. Then you will see k123 at your screen. Now push vol-, and chan- at same time. You will enter service mode. Look for "error no reset" change the value to 0.
