I try to turn it on but it just blinks on stand by

Try as suggested to count the blinks to see if it is an error code or not. blinks will be in a sequence with a pause and blink the same number of times over and over.

Mine also blinks 34 times and then turns back on

count the blinks call tch support for help

Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.

Try this link after you count the blinks.

Try to remove the vertical IC sometimes it become Shorted causing the B+ to drop. after removing try to switch on back check the B+ if ok and the LED not blinking then change the vertical IC.

On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

Try using another power outlet, if you are using a power distribution board then try plugging the TV directly into a wall socket. If using an extension cord then try with another cord. It also maybe that the factory lead that came with the TV is faulty, any of these problems may be restricting the correct amount of amperage required by the TV unit to operate.

stand by timer is blinking green tv will not come on

I will need to know the model number of your set to help you as well as if the light blinks a certain number of times in between pauses. Please respond to this same post.
