I was wondewring if anyonoe could help. I was told that by a tech that I needed a new blue tube in my KP-57HW-40 TV.
So I bought one and put it in plug all the wires back where they came from and now when I turn the TV on it comes on for about 5 seconds
then the blue tube goes bright and right away shuts down the TV. The red light flashes 8 times. Before I replaced the tube the TV would stay
on, it would have a good picture for about 15 min. then go all blue but would never shut off. I thouhgt I needed the red and green tubes but
the tech that checked it said no it was the blue tube pulling all the power from the other two. Any thoughts or suggestions?
Thanks Don Mc

Hi Don,
the first thing I would check is the focustat (the black box on the front of the tv with six adjustments on it), and make sure all the cables are
seated into it (from the back side) tight. CAREFULL HI VOLTAGE!!! maybe you pulled the screen grid wire off when you were replacing the
picture tube. I suppose it could also be the block itself. maybe you should see if you can control the brightness of the blue tube by turning the
screen voltage adjustment up and down. (I believe it is the bottom left adjustment) if you cannot it may mean that the block is bad. It could
also be a shorted cap on the video board as well. I can't think of anything else off the top of my head.

It could also be that your new crt it bad. If you had it shipped to you and it wasn't packaged to survive a nuclear bomb the elements could
have been damaged in shipping. they are fairly delicate and not made to be bounced around a lot.

justin, I sent out that service manual you asked for. Thanks for the assistance here.

Good afternoon are you talking about sending me a service manual? I thank you if you are. Just to let you know that the TV tube was indeed
packaged away very securely in two different boxes.

Larry how was your new year? I have a small question last time I told you, my sony tv kp-43ht20 was blinking six time and I didn't have my
remote rm-y908 to diagnostic my tv so I bought a sony remote rm-v202 but is not doing anything. The diagnostic can only be done with sony
remote rm-y908? Thank you Larry

Although the remote you purchased, the RM-V202, is a Sony remote, it is a universal replacement remote and if some of the functions do not
work properly on your TV set, that is the reason why. Not all remotes are alike, even if they are the same manufacturer. You will need to get
an ORIGINAL replacement, not a UNIVERSAL replacement.

Hi Larry,
We have the KV36XBR (blinking issue 7 times) with our Sony. Just the other day. It had sound and no picture.Today for giggles I decided to
turn it on.It turned on! And now we have a clear picture and full sound. What gives? Is it possible that it can reset it self? I'm affraid to turn it
off now.
Your help is greatly appreciated!
Sincerely,
David

Larry, thank you I guess I don't have no choice but to get the tv remote from ebay.

justin nichols said: Hi Joe, I couldn't help but notice you're post so I'm gonna reply. With a picture tube you could get an internal short
and still have it be "lit". the question is, when the screen goes blue, do you see retrace lines, (lines running horizontally across the screen at a
slight angle). If you do, there's a good chance of a short or at least leakage in the picture tube. It's a hard thing to test for because like a
