I have a KV-34HS 510 Trinitron that I purchased in early '04. Great set with a wonderful picture! We had a power outage yesterday, and since then, the unit will not turn on. When I hit the power switch, all that happens is a double "click" like it turns itself on-then off. Kinda like it is trying to reset. The picture remains black; no blue or snowy screen... I called a local service group that instructed me to disconnect, wait five minutes and then read the number of red blinks on the small LED light on front of unit. Six blinks, 3 second pause, and then six blinks. Repeated.. The power failure failure occurred during a heavy rain. No major lightning and I do have surge protectors at the outlets that supply power to this unit and accessories. Anyone have an idea? Thanks! |

Plug strip surge protector generally don’t work after they have been hit by a spike or two… If you have that kind of surge protection you may have gotten hit because of this. Do not trust a $20 surge protector to protect thousands of dollars worth of investment. ETA: If you did get hit your homeowner insurance may cover it. |

You don't have to be hit by lightning to have damaged equipment. When the power comes back on, there is a series of surges as hundreds of thousands of devices all try to come back on at once. This is very bad for electronics. My parents lost one of their DirecTV receivers in the last outage. You should be using a quality surge protector that comes with insurance for items plugged in. I use Panamax protectors with $50,000 coverage. -Troy |
I don't know, but I bet I know where you can find out!! AVSForum.com It's like the AR15.com of Home Audio/Video/Theater!! Futuristic |
Not true. I'm a repair tech (sorry, TV"s are the one thing I DON"T work on) and we get shit-ton's of equipment after lightning storms/ surges. Our TV guy gets most of them out for under $80. Just find a decent shop and you'll be good to go. For instance, my shop charges a bench fee (usually $25, but larger TV's are more) and if it's less than $75 we fix it (bench fee goes towards repair) anything over that we call with an estimate. If it isn't fixable you're only out the $25. Hell of a lot cheaper than a new set!! |
Continuous Blink Once A Second, No Pausing As Discussed Above--- No reply from the jungle IC301 (data bus is busy, shorted to ground or held high), IK video path is defective. ONE Blink--- not used for the self-diagnosis TWO Blinks---B+ over current protection (OCP) , unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits. THREE Blinks---B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. FOUR Blinks---No Vert. Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505 FIVE Blinks---AKB circuit (AKB), 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. Also unit be in IK blanking, try turning up screen slightly. SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402. Intermittent problems ?? This is a great feature. You can also bring up these fault codes ON-SCREEN to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, Press the following buttons: Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC. We have repeated them in parentheses in the text for the "Blinks" described above so you can correlate between the diagnostic screen and the blink codes. So, now that you know about these self-diagnostics, how do you use them? Say that you have a set with a black screen. You see that the LED is blinking 4 times....This would tell you that you have no vertical and that is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault. It's not a sure cure, but it's a little better than a poke in the eye with a sharp stick. IMPORTANT: after you repair the unit, PLEASE clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode ( display, channel, 5, volume plus, then power ) then press 8 and Enter, which of course returns everything to the factory preset condition. |
Like I said, I don't do TV's but that looks correct according to the post above. If that's the case, it's an easy fix. The horizontal output I.C. is usually $5-$10 (after mark-up). A reasonable shop would bill between $50-$80 for labor. Call around and see. |
