When turning on , no picture no sound on tv. Only blue power light is on. Any idea, whats wrong ?
The input signal is missing and the blue screen background comes on the screen. Change the input to some other device which you are sure works and see.

Hello, two things, one if the unit gets stuck there meaning that the W stays there and it shows that on the screen thank your main board is stuck on the boot mode and you will need to replace. The second is if the W goes away than you need to see if you can plug something in and change the input mode (even if you can't see anything on the screen) so that you can see if there is any sound coming in to the unit. If this is the case than you are looking at dead inverter board. If you would like to further troubleshoot than please email me at [email protected] for further assistance. If this information was useful please rate me on this webpage.

Vertical color scan has an open or short..............it could also be a ground problem with in the V-color scan circuits...
If you tap the tv and the color bar is gone then its a ground problem with in those circuits above. Needs a solder re-flow and check the condition of ribbon cables.

It may have bad T-CON board or the bad DC feeding it. You need to check the DC voltage feeding it.
