Question about Vizio E-series E241-A1 24" LED TV 1920x1080, 60 Hz, HDTV
Normally the white LED comes on bright for a few seconds and then dims when the screen comes on. Warranty expired the week before so I took off the back cover to check for burn marks on the circuit boards but found none. Tested the output voltage off the power board going to the main board and it is fine. I suspect the main board went bad. Before I get a new one board does anyone have any experience with this same problem?
Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.
