SOURCE: Sony KDF-E55A20 55 in. LCD... Problem red light flashes 5 times

A 5 blink error indicates a bad lamp driver. However a lamp may possibly cause this too. I suggest putting a new lamp in if you have one just to verify the lamp is not the problem. If it still fails with a new lamp then the lamp driver is the problem. This part should be replaced by a Sony authorized servicer. The lamp can be replaced easily by you. The lamp replacement instructions are in the TV's owners manual. Good Luck

SOURCE: SONY GRAND WEGA KF-50WE610 can't turn on TV screen.

Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Thanks,
Dan

SOURCE: Standby Indicator flashing SONY KD-32NX100U

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1Theinternal circuits are jammed because of electrostaticcharges accumulating on capacitors, or because of a wrong voltage readby the main chip on your monitor controller board. this started theprotection circuit.

2 The protection circuit detected a wrongvoltage or abroken contact, identified an internal fault and kicked in, starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Payparticular attention at inverter and power board, power board can beinspected looking for bulged or leaking capacitors, then tested with amultimeter. The inverter is more difficult to test , there is need toread voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

Red flashing light


  1. Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Sony KP-FX43M31


On the Sony FX43 100Hz 43-inch rear projection TV, three flashes indicates an Over Voltage Protection problem, occurring in one of the power supply circuits T603 or R672.

The fix will most likely cost more than the set is worth second-hand, I'm afraid.

Sony tv wont start up???


The flashing should be a repeated number of blinks. Please post that count as that will indicate the circuit in which the set detected a problem. The set is in protective shutdown. Using hte blink count, we can determine the possible problem and solutions.
