    Jack Munster Have checked all voltages and they're all correct, Have also replaced all 3 boards, power supply board, inverter board and main board except T-Con Board. Tried to update software on main board but it won't update. Could it be the CCFL lamps ? or Bad Panel ? Nov 21, 2013

SOURCE: Dynex 37'' LCD TV (DX-LCD37-09) wont turn on

The registration card may help with warranty going through the TV company. But, that's the last option.
You can fix it yourself by replacing this board. The board number should be BA71G0F01043.

The 8 Inverter transformer are the problem. They are on many TV power boards that are causing the same problems.
Ebay is selling a couple for $49. Good price I think.

If you decied to throw the board in the trash, let me know. I maybe able to help you fix it so you can have a spare board. I fixed mine that way.

Dynex dx-40l150a11 tv turns on and says "Please Wait" after that goes blank with no sound or video. Changed main board and power board already.


Sounds like a software corruption. Just check it by updating its software [firmware]. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.
