Its most likely an intermittent lamp. The lamp door is located behind the front panel. The front panel can be removed after loosening the two thumb wheels located on either end of the TV in the rear. Observe the light coming from the area around the lamp door. If you see that the light is going out, its the lamp. You can also access the self-diagnosis menu by using the remote control. Start with the TV off. Push the "mute", then the number 5 button, and then the volume down button followed by the power button. When the picture appears, the menu will been visable. If there is a failure with the lamp, or a fan, or many other areas in the TV there will be a number value to the right of the parameter that indicates the number of times the error has occurred.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.....

I have a Sony WEGA KDE-42XS955 that takes 5 minutes for the picture to appear. Once it appears..works great! If I just leave it turned for it will work fine. Any idea what board needs to be replaced?


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.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My sony wega kf-50E200A tv keeps turning off. during each cycle the green light blinks 42 times and the tv comes on again for about 3 minutes and it happens all over again


More than likely the power supply is defective, but without testing and the repair manual that is just a guess, you make the decision to replace or repair the TV.

No Video Or Sound - Stand By Light Flashes 5 Times


If the tv was made before December 2008, there is a capacitor settlement from a class action lawsuit by Samsung. Supposedly (at no charge) they will send a repairman to replace the capacitors.
