Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

IGO tv connected with dish sound come from tv but pictur not show only blue color show


Component RCA Connectors are RED, BLUE, GREEN for picture. Sound is RED and WHITE. The red and white for sound work the same with the YELLOW that does picture. If the RED, BLUE, GREEN are in the wrong order you will get a blue or green picture. For the sound, try the other red and white connectors nearby. Make shore the right red connectors are connected correctly for sound or picture. Otherwise there could be a cable fault or a TV fault. If you get the picture right but not the sound, connect the sound into a stereo.

Playback movie pictures or sound


Movie pictures can be played back with the camera, but not sound. However, when the camera is connected to a TV, both movie pictures and sound can be played back. For playing back movie pictures or sound on a PC, the QuickTime™ 4 is required.
