My Sony Bravia TV - Model #: kdl-52z5100 no longer powers on. There's a red light that blinks twice whenever I attempt to power it on. Please help


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Television when turned on: light goes to green then flashes twice. green light goes out and red light comes on. tv will not come on.


If the Red Light Blinks twice and goes out, the TV is in Protection Mode. There are 6 voltage outputs to the lamps around the screen. If one of those outputs is missing the TV will sense that there's a problem and refuse to turn on. The predominant failure in this model are the output transformers on the Inverter board. A properly trained technician can measure the windings on each transformer and look for an open circuit, if one is found, replace that Transformer. i was given one of these sets from a friend and I replaced an output transformer ($11 w/shipping) and I now have a fully functional TV/DVD Combo. Also verify that all of the connecting cables internally are properly seated, there have been reports or the ribbon cables from the Power supply board to the main board above it not being fully inserted and it also prevented the TV from turning on. A word of caution. There are VERY High Voltages on the inverter circuit board, only persons with proper training and knowledge should attempt this repair.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Plasma turened off and red light flases twice


Red flashing x2 = Panel power supply fault

It would be easier to replace the power board than attempt a repair at component level (dangerous voltages)
