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.

Sony Wega Plasma 42XS955. Over 2 wks., gradually

I would check the capicitors on the power supply to see if the they are bulging at the top or leaking. I had a Samsung lcd that starting taking and hour to turn on then eventually it would not turn on. So I checked the power supply and saw four bulging capacitors that I replaced and now it's working like new.

3 blinking red standby lights, 2 sec pause, but no TV picture

Hi, shutdown with a 3x blink pattern occurs if the 12v from the power supply (GF1 or GF2 depending on model) is lost at CN6153/pin 6 to the AU Board Q1224 to Sub Micro IC1205. The suspects, in order of likelihood, are (1) Power supply and (2) the AU board.

Green light flashes twice then turns red

Please ignore the first solution as that blink code definition is for a Sony CRT based set, NOT an Emerson.

Carefully examine the LCD panel itself with a flashlight and look for small cracks. Based upon your description of events, I think that the panel is actually cracked. This usually only prevents a picture from showing. The red lights are an indication of an internal problem and the set is in shutdown to prevent further damage.

Without seeing the actual unit, I cannot make a definite diagnosis, but I would initially suspect a power supply problem that may be relatively cheap to fix. If the set is relatively new, I'd invest in a detailed repair estimate. Post the info here from that estimate and we may be able to walk you through the actual repair.

Picture & sound go off for 1-2 minutes, then return.

The most likely the TV has a power supply related problem.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
