Vizio logo does not light up amber when plugged in but turns white when power button is pressed. no picture or sound. Big Transformer on power board makes a light buz sound when plugged in also.

1. When the TV powered up, please measure the 24V, 12V & 5V are there, if one voltage is missing, you may have a defective power supply.

2. If the power supply lost the 24V source, you may unplug the power supply connector on both the inverter board, then power it up, if you got the 24V back, you do have a defective inverter board, you may unplug them one at a time to locate the bad one.

3. If the power supply & inverters are good, you may have a defective main board. The common problem on the main board is that a voltage regulator is bad, you may use your millimeter to measure them 1 x 1. The out put voltage (on the heat sync) should be 1.25V + the control voltage (Pin 1), for example: if the control pin voltage is 0, the output voltage should be 1.25V, if the control voltage is 2.05V, the output voltage should be 3.3V, if one of them is out of range, replace it, you may find the part from Digikey Co. The part number printed on the regulator is AMC1117.

Good luck!

Check the fuse at the main power supply regulator. If found burned, check and replace faulty component/s at the power supply regulator section. If you are not handy, contact any experienced service technician.

Have a sony tritron wega flat screen tv and it wont turn on, its red light blinks three times, what is the problem and how do i fix it?

Your TVs horizontal output stage is not working. That means, the line output side [LOT and related components], are inoperative. It may be due to some secondary missing voltages from the power supply section of your TV. There may be some open resistor, or short inside the Line Output Transformer [LOT] itself. Anyway that side is not working. Your TVs power supply regulator system has no trouble. It supplies the required voltage to the other sections. That is why you see the LED [Light Emitting Diode], fitted in front panel of your tv blinking for some time and shuts off. As soon as the TV is switched on, the power regulator system inside the tv will supply all the necessary secondary voltages to all sides. If at any section misses the required voltage, the system control Ic will detect it, and will try to rectify that. It is so programmed at the factory. If it can't do it, it will automatically shuts all the supplies from the power regulator system. It is a protection added by sony to all models of their Tvs.
You yourself cannot detect and repair this fault. Get the service of an experienced technician.

32'' sharp aquos tv will not power up.

Look for the fault in power supply board. First check the fuse and replace it if burned. Then it could be a Voltage Regulator chip(s) burned (they look like transistor with 3 pins). You can test it with multimeter, they could have different pin outs, but generally it should read around 5 MOhms in 2 sets of 2 pins. Or it could be bad capacitors, look for swallen or domed capacitors; measure them with capacitance meter, sometimes they dry out with time. Or it could be other parts in power supply.
