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.

Sony bravia 50" red light blinks 6 times.


One thing you can try is to remove all cords attached to the tv including the power cord. wait a few minutes( maybe say a short prayer) then plug the power cord back in and try turning on the tv if it powers up. it maybe a short in one of the units that were plugged into the tv. If it still does not work it maybe a circuit board problem. Sony Bravias have been plagued with a lot of circuit board issues. type in Bravia problems on any search engine and you will see what I mean. You may be able to get it repaired but you best course of action is to buy a different tv. a Vizio or Samsung or anything but a Sony

If that is a chip in the power supply unsolder all pins and get a pin out of it to test it for a short--if shorted and no short to ground at HOT replace it.

Brand new out of box Sony KDL46V3000 will not come on. Green light at bottom comes on but no picture, volume, or menu. I bought this TV New and never unpacked untill we completed remodel about 13 months...


Best take the tv backcover off,check all circuits boards for lose wires or broken circuits boards.Secound,take a air hose or a fan turn on high,blow in all the circuits boards.Third put the tv back together again.Wait about 20 mins,plug in the incomming broscating signal cable first,than the power a/c cord.Turn the tv on.The tv should work.That should solved ur tv problems.

Sony Vega Digital TV model KD-28DX50 U


the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, vif,sif, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service technician
