Standby light flickers constantly in red but will not switch on
SOURCE: No Picture or sound, red standby light blinks six times
Sorry for how long it is but you should be able to find what is wrong in this guide
If you have any questions please dont hesitate to ask
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 selfdiagnosis
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 0 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.

The 5 blinks can indicate a picture tube starting to fail. Carefully open up the back and look for the flyback transformer. It will be the part with the large red wire coming out the top that goes to the side of the picture tube. There should be 2 controls on the flyback, screen and focus. Turn the screen control slightly clockwise. If the set stays on, the picture tube is starting to fail and you have bought yourself time to find a replacement. If that fails, then you will need to investigate other possibilities that will involve soldering. Let me know if you need to do that.
The 6 blinks indicate no horiszontal. This can be as simple as a couple of bad capacitors or the "jungle" IC. If you can solder, please post another question with the model and a brief description indicating that you can work in the set and we'll continue to track this down.
Thanks,
Dan

I
have over 10 years experience in electronic tech
support.
I
know this isn't what you want to hear, but the problem you've
described can't be fixed with troubleshooting.
Your TV
will have to be repaired. There is a part that has developed a defect
and needs to be replaced. If you're still in warranty, the TV will be
repaired at no charge to you. The warranty would likely be at least
one year from the date of purchase from the manufacturer. If you
purchased an extended service
plan
they will repair the TV at no charge as well.
If the TV is no
longer in warranty, it will likely cost a minimum of $150 parts and
labor. This is assuming that you only need one circuit
board
or small part. If the problem is more than one of the circuit boards,
the price of repair could go much higher.
I hope I've provided
you useful assistance and that this information allows you to make an
informed decision as to how to proceed from here. Please be sure to
vote on my response. I hope I've earned a good rating from you
today.
Please let me know if I can be of further assistance.

Hi,
According to the LED error code (11 times blinking) the problem is in "Jungle controller 8 volts" which are not being produce, this kind of fault bit technically difficult to and i suggest you to contact any expert to find the cause of not producing 8 volts supply,
Hope you will understand my sayings,
Thanks for using fixya.
