Circuit diagrams of many popular brand TVs are given.
Back - light 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. http://electronicshelponline.blogspot.com/
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.
The schematic diagram is going to be very hard to get. We do repairs on this model. What information do you need? The most common problem is the capacitors on the power board. You can find this repair guide at: http://www.ccl-la.com/blog/index.php/repairing-the-samsung-940mw-lcd-tv/ If you need other information then let us know at: [email protected] and we will get glad to assist you in the repair.

Does anyone have a good modification for these Bush PSU's .
I have replace the capacitors etc in a number of these sets with higher voltage , high temp caps but they sometimes only last 4-6 months.
surely someone has found a way to modify the boards to get rid of this problem completely.
