Green arches Every time I turn on my Sony TV it has these green arches on it. Plus about 45 seconds later it turns off. Then the stand by light flashes 8 times. What should I do to keep it from turning off?

Klv32s310A sony bravia gets start on with green light and after a second turns to stand by mode blinking the red light 6 times after each 2 second interval


Hello Sagar,
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.

succes,
Walter from Antwerp, Belgium.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

When I power up, 5 seconds later this back projector TV turns itself off


t does sound like a bulb problem, either its over heating and shutting off to protect itself, or its already shot. Give a TV repair shop a call and see if they can give you an approximate price, then decide to ditch or repair it.

Sony kp-57ws500 green screen then auto shutoff


I have the same tv and it did the same thing only now it has red hues all around the picture as well. The service guy told me it was the green tube and it would be about $500.00 to replace and may not fix the problem. What a p.o.s. I will not be guilty of buying any other Sony products from now on.

Tv cuts off and green light flashes


If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!
