green led means tv powered on and status ok.
Red blinking light almost always means defect, overcurrent or overload.
6 blinks for Sony lcd flat tv means trouble in backlight circuit, or backlight inverter (backlight illumination or lighting makes your tv screen visible).
common problems in the inverter circuit, which drives the backlight, or shorted drivers, or short-circuit transformers or open circuits. You should find the problem in the inverter circuit, or in the power supply board or in the main board.
Also look for bad capacitors (electrolytic caps) which are bulged and swollen on top.
Decoupling plugs from printed circuit boards can help you in finding the problem board by elimination method.
If you power up the set after unplugging certain plugs on f.e. the inverter board , this could result in getting a green power led and concluding that this board is faulty.
Welcome to FixYa.
My name is John, and I will be assisting you with your issue.
The four (4) blinks mean that you have no vertical Deflection, and
it goes into stand-by (safety mode) for protection. If you are not in
fear of high voltage because it can kill you! You can do this job yourself.
Let me know and I will post it here and the tools needed. Thanks for choosing FixYa.
If the unit is playing normally then goes to stand-by, it could be also caused by the main board and or the ballast boards. If it is caused by the ballast boards, it should give you error code with the red stand-by light blinking 11 or 13 times. If the stand-by light does not blink a code, it is probly the main board.
I hope this helps,
Goes from on to Standby by its self because of protection mode that activates for some internal problem. Do you see standby light blinking on tv front? What is model number of your tv? How many times standby light blinking after 3 seconds long pause? Let me know to find out possible cause of problem.
If you have the above model, then the four blinks indicate a backlight failure. The back light inverter board might be defective or the voltage from the power supply (+24v) is low or missing.
Let me know if you require further assistance.
