Black screen on Toshiba LED TV, sound still working and T-con board has been swapped.

SOURCE: 47inch toshiba lcd tv (HL167) black picture, but

Best to replace both at the same time . Yes they are easy if you can find the parts.

SOURCE: I have a Samsung 60" LED TV. Everything work except I have no picture. I have sound and a backlight on the screen. I can change sources but do not see any images. I think that the T-CON board is bad.

You only have 3 modules in the back of that unit, the wifi and the sound master board and the video board. Samsung knows they have a issue with some, there is a diagnostic mode that will help you to determine, I would contact tech support before I bought a 350.00 module just to confirm, however I think your on the right track

SOURCE: 47' (sic) LED TV, model number m470vse. Why doesn't the backlight work?

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 trouble shoot. Contact any service technician. The circuit will differ with models and versions.
