Question about Coby 40 TFTV4028 LCD TV
Tv show blue coby screen then turns off changed power supply and main board wondering if it could be inverter board?
First you have to make some checks , play audio ? have to look at the screen closely and make sure there is image. If you have audio or image is not the main board , is the inverter . But if the logo is turned off and no picture or sound , it may be the main board. Discard the power board measuring voltages . Luck .
