hey I was wondering if anyone has a service manual or schematic for a Sony kv27s42. I have four blinks and hopefully I can just replace a few
parts and get this tv workin again.

even though i never got any comments to my posts on july 6 and 10, i figured i'd give an update, i just picked up my KV32FS16 at repair shop
last night after they replaced the flyback transformer for my screen that had red flashes until it went to a blue screen with white horizontal
lines, with diag code of 5 blinking lights (even though my research on here and on web didn't really point to that for 5 flashing lights) and all
seems ok.
i do have 2 quick questions though, i see on the invoice that he used transformer pn 1-453-338-41. when i look up my original part at
partstore.com, it was -11, however i see that that part was superceded by -21. no mention of -41 for my specific model. when i look up -41, it
lists -41, -21, and -31, with a note saying that -21 is a direct replacement of -41, but not vice versa. can i assume that vice versa would be the
case and that the -41 should be fine for my tv even though my model was not listed under -41. i'm sorry but i'm just being particular with the
part numbers.
second, while doing a quick browse through all the service mode settings after the repair (i had written them all down previous to the repair),
i see that the only one that is different is PREL, pre-shoot/over=shoot, changed from 0 to 1. what exactly is this setting for? would
something during the repair have changed this, or did/could it have changed when i did the self diag mode reset to reset the counter for the 5
blink error codes to zero since the repair tech did not do this? tia.

I would like to say I am a first time visitor because my Sony KV 34XBR800 trouble free til now. I am getting no picture or sound when
powered up. I do see 7 blinks on the standby red light. I live in a small town and was wondering if my problem would require a proffessional
TV repairman or can a novice take care of it?
Any help or guidance would be greatly appreciated.
Thank you in advance,
Ray

Hello Larry and everyone else!
My problem is with a 5 yr old KV-36XBR450. It is periodically shutting down. When this happens the power light blinks 4 times. I went in
to the self-diagnosis menu and it lists V STOP and AKB as having had an error. I called the Sony recommended service shop in my area. The
service technician diagnosed it as a problem on the D board. The shop called the next day and said they could not get a new D board and that
they would have to identify the exact problem and repair the old board. The charge would be $600+ (in addition to the $85 service call fee
already incurred!).
I am of course unhappy with this answer. I find it hard to believe that Sony no longer supplies new D boards.
My questions are:
1) is it true that a new D board cannot be purchased from Sony for this TV?
2) if a new D board is available, what would it cost and where can I get one?
3) if no new D board available what is the best source and price for a used one?
4) my only electronics experience is assembling my own desktop computers. Should I attempt to replace my own D board?
Thanks to all for a very informative and helpful web site!

Gamb00ler, If I were you, I would search all of your address book for a friend who may have a little more printed circuit board experience then you do. This is not really a hard thing to replace, but there is a little more
involved then a simple plug to plug replacement. the high voltage lead for instance, it comes off a special way, and the service manual shows exactly how this is done, and also any adjustments that may need to be done, such
as convergence. No, every board is not exactly the same, as part tolerances are a bit different on every board. You can go to http://www.tristatemodule.com/. Find the phone number and see if you can get the D board
number off of the original board, as they have a few on special right now for like 80 bucks! Heck the fly-back cost more then that. The new D board also includes new convergence IC's. So if your picture tubes and the rest of
the TV set is in good shape, you should get several more years out of your TV set. Oh, if Tri-State does not have the board, or cannot repair it for you, try going to ptscorp.com, find the phone number there, and call them to see
if they have any exchange boards or maybe can repair your board for you. Sorry, the best I can do for you right now. You really should go to http://www.servicemanuals.net, enter your model number for the service
manual, and download the manual, as you should see how the board comes out, and like I said before, any alignments you may need to do. Good Luck with this repair, and let us know how you make out with this repair.

bayner said: Hi Larry, Since you don't have the manual,could you tell me if 6 flashes and 7 flashes usually indicates a faulty D board. I got
an estimate over the phone. $200 pick up and probably $500 for repairs. I have an electrical background and can replace the board myself. I
just want to narrow it down. I would rather change the whole D board than try to chase something down on the board itself. Visually the
board looks fine. I did find a bad connection on the white wire off the flyback x-former where it connects to the board that plugs on to the
tube. I soldered that and actually got the tv to work for a short time.Now it is back to the 6 flashes and 7 when you turn it on. Any help would
be greatly appreciated. This tv is driving me crazy!
I, too, have a Sony KV-40XBR800 that won't turn on and is flashing 6 times. Did you manage to resolve your problem or, at least, find out
what the six flashes mean?
