Sony kp-51hw40, akb code 1 and hv code 1 tv would not shut off
My tv while in dvd video mode automatically changed to cable video and when i tried with the remote to go thru the video back to dvd video it wouldnt change to any other video mode except cable, when i tried turning the tv off it went right back on. hit the power button on the tv and it went off and right back on and still could not change the video mode except for cable video. pulled the plug and disconnected the coaxial from the satellite and let it stand a while then plugged it back in and everything back to normal..video mode were able to change and when i pulled the service mode codes with the remote i got AKB 1 and HV 1.
Fyi about 3 months ago i had the blue tube changed and I am not sure if those codes could have been from then or not. tv has been on for a couple of hours since and everything good.......If i had to randomly guess i would say possibly the green picture tube since i have read these Sony models had all three picture tube problems..Also it been really bad weather and reason i write that when this happened is maybe possibly the satellite had something to do with the problem....Any help or ideas or even an educated guess would be greatly appreciated.

Hello, you can go into the menu and rename the inputs to what you want example: input 1 can be cable box, input 2 DVD etc. In the menu, go to "inputs" to the side of each input there are several name choices to choose from....tks
hello 5 blinks means, 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, 219, 220 on the A
board. In addition, unit could be in IK blanking, try turning up screen
With both of error codes flashing, the problem is trying to figure out wich one to focus on. The flashing 6 code is an indication of HV failure which would then cause a vertical failure(4 blink code). There are so many things that would cause this problem. I can narrow it down to the "D" board to fix your problem. If I were there to troubleshoot it, I could narrow it down further I.E. flyback, HV distribution block. I suggest getting a tech diagnose the exact problem. I wish I could narrow it down better for you. Please take time to rate this solution and if I can be of further assistance, let me know
I had the same problem. i was told by one of these so-called experts @ fixya that my flyback transformer needed to be replaced (the 8 blinks on the standby was the indicator). but i recently replaced it and im having the same problem. sorry. no advice. good luck.
v1 is your verticl scan has stoped for a reason,akb 1 is the feed back from the crt to the video ic, hv 1 is high voltage stop the set ,clear the error codes and start again record them and conpare the results for the true fault.
How is this distorted? Does DVD only have Video/Audio jacks or do it have RF output connection and if so have you tried going inset that way? How does it looks with only Dvd Logo on? If Logo is ok then I would look for some other problem.
Yes, you are correct on the phrasing. The CRT's were a common issue with these units and all three must be replaced as sooner or later the green will follow the other two CRT's. It was a great model and had a beautiful picture when operating normally. The CRT's are costing about 200 each for rebuild as the green and blue are mostly no longer available. Your repair cost are going to approach $1000.00 or more.
