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.

Sound ok but no picture


Check the high voltage on the picture tube it should be around 26 thousand volts. Check the back of the picture tube to see if its lit.

Samsyng pn42b450b1dxza hit by lighting now tv sits there and makes clicking sound . I replaced power board didn't help still making sound what could fix this thanks Dave


Nobody can predict what might have been happened or damaged to this TV by lightning. Anyway, it is clear that the power supply section is somewhat good, as you hear relay clicks. The main board and other boards should be checked. It will be best to contact any service technician in this case. If you're sound in electronics, and wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Flip card, can be selected by the drop-down list, by 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.
