Generally the best route to take is going to a TV repair shop. Reason being if the television needs to be properly troubleshot to insure you are purchasing the right part. Average cost is around 2-300 dollars.....

Seiki tv has no picture. The picture went blank, how do I trouble shoot it to find the problem?


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Seiki led tv has sound but no picture. The picture can be seen with flashlight. We tried resetting default on menu with tech support, still no picture. Has no backlight. Which part should we replace?


You are correct, this is a backlight issue! The screen inverter is usually built into a circuit board, if you want to attempt this yourself you will need to access the circuit boards to see which one you need to replace! If you open up the TV and post a picture we will be able to point you in the right direction!
