We replaced the G1 Board based on the recommendation on page 8 of the service manaual:
Low B Error = 6 blinks = Probably Cause is No "DD 6V" output (G1 board)
We will check into it further. If we replace the G2 and that is indeed the problem, should the set automatically come on or is there some
type of reset that will need to be performed?

I have a Sony KDF-55WF655, after a couple minutes my screen will go blank and the standby light will blink GREEN about 35 times then the
screen reappears for another minute or so. This will happen over and over. I tried pulling up the error log with no luck.
Thank you for the help.
During my wait for a response I checked some other sites and found someone had a similar problem and they replaced the balast and the
lamp. Well being impatiant as I am I opened up my tv removed the lamp and noticed that there were screens on the top and bottom of the
lamp assbly and a tube at the top of the lamp receptical. I assume that this is some air flow path. One of the screens was about 95% blocked
with dust. I cleaned it and put it back together and yep it works (so far) I have a feeling I just saved myself $500 or so for a gram of dust
SWEET!!!
I still would like to know how to pull up the error log for my model tv and how to get a repair manual for my tv?

Larry, hope you can point me in the right direction. I have a KV-30HS420 that I am getting 7 blinks on. I have looked over the information I
can find but can you point me in the most likely direction?
FYI, while no TV experience, I do have an electronics background and the tools to perform the troubleshooing & repair if I know what I am
looking for.
Thanks,
Tom

Hello. Unfortunately my trusted 7 year old Wega KV-32FS16, BA5 chassis, manuf July 2000 decided to take a dive the other night. We had
left it on and went upstairs for awhile and when we came back down, the screen had changed to a blue screen with horizontal/slightly
diagonal lines on it with the tv show picture as a ghost image, sound working fine, but standby light flashing 5 times and repeating. Changing
channels/vid inputs sometimes brought picture back momentarily, however it immediately was flashing red colors and then would fade to all
red before turning to the blue screen with the horizontal lines with a slight diagonal to them as well as the center lines had a slight hourglass
effect to them. Flipping to blank inputs for vid 1-4 would just give the blue screen/lines. Also noticed the viewable picture shrank about 1/2-
1" all around viewable front 4 sides. Turning off and on sometimes helped, but again not for long, and sometimes there was a wierd squeak
and electrical snap sound. After some cursing and stuff, got on web and ended up here among other places. Found a couple posts elsewhere
on web mentioning checking T501 and Q502 solder joints on A-board. Pulled tv apart and looked at things. I did find these solder joints and
they appeared ok, but I'm no electronics expert. I tried poking/pushing with a stiff rubber hose at certain parts/boards with tv on and there
didn't appear to be any obvious changes. Can any of you experts help me out here? Probable causes? More things to check? Am I going to
need to take to a repair place? Any ideas on repair cost? Anyone know any good ones in Reading, PA area? We really like this tv and didn't
have any plans of replacing it any time soon. Of course the irony of it all was we were in Circuit City the previous night just walking through
tv section and mentioned we would only consider getting something new if ours broke. As well, I just self installed 2 other Comcast cable
boxes on 2 other tv's in house the same day. Talk about bad coincidence. BTW, I have moved this tv out of the way and moved our 27" from
upstairs in its place and all works fine, so not a cable problem at all. Please help. TIA.

Larry thanks for the info on the two diodes i was looking and figured that is what is wrong i opened it up and found what appears th be a little
burn on the board coming out of a diode. it is black corrosion. i am not sure which one it is because it burnt the #s would i be better off just
replacing the whole board? if so do you know the part # and where to find it. thanks for taking the time to answer my questions.

Larry Dillon said: PWP, Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then
goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C
board, also check Q218, Q219, Q220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly. If you have no
solid state repair experience, I'm afraid this is not a repair you should attempt. Play it safe and call out an authorized Sony repair shop to
assist you in this repair.
Larry,
I have the same problem, five blinks, but on a Sony KP-61V80 projection TV. I have already replaced both the A and G board inside with new
ones. There are no video or sound. Should I try replacing the CR/CB/CG boards? Any help on this is appreciated. Thanks!
