Question about Sony KP-53HS10 TV
My TV is a 2000 model and a couple of weeks ago the standby light started blinking 5 times. A week later the screen blinked on and off a few times and now it will do it for up to a hour. I'm not sure, but it appears that the color is not right and when I turn the TV on now it seems to take a lot longer for the screen to appear than it used to.
When a Sony does what you explain it usually only needs it's screen controls adjusted. This would be the first thing before replacing parts or any other trouble shooting, To do this you have to remove the speaker grill, there usually are two screws down low that are covered by plastic covers, once these are out the bottom pulls forward and slightly down. Then there will be another cover, remove that. Now you should see the inside of the TV. Near the front there will be a control ruffly the size of a pack of cigarettes and have six controls on it, Three are for focus and three for screens, Next find a video source that has no input, this simply means change to a input that has no signal, and gives you a black screen. Next simply turn the screens clockwise till a faint glow and retrace lines appear, then turn it back down till the color just disappears. Do this to all three, then you can re-glue them with fingernail polish if you want to.
Thats the simple way to set the levels on the CRT's, Sony's have a circuit that mutes the video until all the voltages are within a certain range, if the voltages are too far off it will give you the five blink error code, now if does not fix the problem there are other problems, This can be any thing from a weak CRT to a capacitor failing. And on a final note it is best to let the set run for at least 20 minute before doing this adjustment to let the voltages stabilize, and it is best to check it after another twenty minute to make sure it stayed
