This is most likely due to 2 problems -Temperature or a bust capacitor,

1. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use hairdryer., but don't hold the dryer too close(say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Reseting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.

2. You can also try this..if you unplug the TV, and hold in the power button while plugging it back in, this will reset the TV, and sometimes it comes on.

3. If you want to go in for a long term solution, you can easily replace the whole power board (should be about $20 or so), or just change the faulty capacitors. You can make out which are faulty, because their caps will be swollen on top. Here's a pic

Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you.

PS. The capacitors are usually 680 - 1000 micro farad and 35V. however, if you dont find 35V, you could use a 50V as well. They will be slightly larger, but you should be able to get them to fit in.
You can buy the capacitors online from HERE or HERE if you wish..They cost $0.068 - $0.85 each, depending upon the model.

Hope that helps...Should you have any further questions, please feel free to post them here.

TV won't turn on, standby light just blinks 9 times


hello, Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).

Count the number of blinks of the standby light. It will bink a count, pause and do it again (Common counts are 2 -9) Give this count to a Sony service center and they can help you know what the issue is. (Probably the lamp)

Set wont turn on, stand by lights blinks 9 times


Have the same thing happening with ours... we were told by a repairman that it needs a new D Board. He told us that if we could fix the TV for under $500 that it was worth it, if not (which of course, we can't when you add in labor cost) don't fix it. I like the TV but I can buy a brand new flat screen for that!
Good Luck
