Is there a way I could send you file?
Thanks again,

That means you most likely have a bad picture tube, or a problem in the CRT drive circuit. These types of repairs, Im afraid are not and
should not be attempted by the novice handi person.

Hello (Larry?). I'm a new member looking for help. I have a Sony KDF-70xbr950 television with a mind of its own. Once its turned on, it
turns off by itself after about 5 minutes. It stays off for about another 2 minutes and then comes back on. This goes on repeatedly. If I shut
off the set, the red power/standby light blinks on/off five times. Important to note. I had this problem last year for a couple of weeks and it
went away by itself. This time, the on/off cycling is more frequent.
Most posts I've seen with similar problems don't mention how it was resolved or how expensive it is to fix. I spoke with Sony reps who gave
me step by step instructions on unplugging and replugging in the TV...then informed me that I would have to contact a service tech. I asked
what the field data looked like on this problem...since I have seen it posted in many places (everyone looking for solutions). They said they
don't have that information available.

I have had a Sony KF-50XBR800 LCD Projection TV for over 5 years with no problems, but it has now developed the symptom of turns itself
off after a minute or so, stays in standby mode for a bit and repeats that cycle. When I turn off the TV the standby light blinks 5 times which
likely indicates the AKB circuit - based on earlier posts. I suspect this TV is old enough to not be effected by the 'updated' blink codes.
Larry, if you have the service manual, would you e-mail that to me (p.amburn@gmail.com)?
Great posts on Sony TVs - very glad I found this site.
I'm comfortable with computers, minor electronics, but have not done TV repair. Not certain if this is beyond my reach for home repair.

This TV set is an LCD type set and has no picture tube. The AKB is used only on sets that have a picture tube. Your problem is a bad lamp
driver circuit. I had the service manual but cannot seem to find it. You can go to http://www.schematicsforfree.com/archive/?
path=Sony%2FVideo, and download the manual for free one time. Just be patient once you click on the button. It will come to you. Then
don't forget to save it to your computer. Good Luck

Hey, Larry
I've been reading your posts and want to thank you for such useful information. This site has to be one of the best I have found on
troublshooting these devices. Great job!
Anyway, I have info to share and info I need to find:
RE: Sony KV-32TS36 TV
Was given this set free of charge. WOW! But it didn't work. Started out without power. Called the local tech shop, they were very helpful.
Had a kit of about 4 parts that are the ususal suspects on these tvs. Cost about 20 bux. 1 resistor, 2 identical transistors and another
transistor.
I replaced the parts, and VOILA! it was alive! now the problem was no video. Lots of noise, though, and clear once I connect the TV cable.
An internet search later found a clue if I hit the TV on the left side, the picture would return. I did that, and it did return, but only for a little
while. If I left the tv off overnight, another whack was required. I supposed there was a cold solder joint, so more searching let to IC301 (the
jungle IC). I disassembled the tv again, resoldered the IC, and anything else I thought could use it. The tv now turned on, and on the first
attempt, 4 blinks then the picture came on. Power cycled a few times, everything seemed OK. Now after about 20 minutes use, the image
and sound started to jump (like the input line was momentarily shorted). I tried several input sources to rule out weather, etc. All the same.
When the tv was working, it also seemed to have poor RGB convergance on the corners. White areas had the primary colors next to it.
Any ideas where I should look next? I have the service manual, if anyone needs it. It covers KV-27ts29/27TS32/27TS36 KV-32TS36/32TS46
models.
I am also looking for an original Sony remote compatible with this TV. Kinda hard to get into the service menu with a universal remote,
although I haven't tried....
Thanks for any advice. My email address is crang94@hotmail.com ifyou are looking for the manual.
*** UPDATE ***
FYI, I fixed the TV. The New symptoms that seemed to poing to shorting or arcing HV turned out to be a loosly installed flyback on the
picture tube. If it weren't for the suction cup, the HV would have probably started a fire within the TV.
Typically, how long after turning on the power, should you see an image? When I turn on the set, I hear sound right away, and the standby
light blinks for about 7-8 times, then the picture just appears. I have never owned a Sony TV before this, so I am not sure if this is normal, or
if there is still another issue.

Hello Larry,
I have a Sony KP-51HW40 television. Here is the problem the TV will not come on and then flicker blue then the TV will turn itself off. The
