Question about Televison & Video

1 Answer

My Sony 46" big screen projection TV comes on for a few seconds then it stunts off and the standby light blinks 9 times. What does that mean?

Most of the numbers on the back are faded away. But I can make out the model numbers k951w. And that's it

SOURCE: Trouble code: Standby LED blinks 9 times

Try pushing the buttons on the remote and let me know what comes up on the screen if anything.
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.

SOURCE: model KDP-51WS655 - blinks 9 times

A 9 flash code is defined as a zero cross failure, basically a power supply fault. It is usually caused by the failure of one or two diodes on the G board D6301 or D6116. D6116 is 871908197 and D6301 is 650056721. If you can get them and are handy with a soldering iron, you can probably replace them. Be sure the set is unplugged and use care when installing them, as high voltages exist in the set even after it is unplugged. If this answer is to your liking, please be sure to rate it. Thanks! Also, a good confirmation of this is to turn the set on using the following error code display method. With the original remote, press the following buttons:
DISPLAY
5
VOL -
POWER
The set will usually turn on this way if the diodes have failed

Yes common problem it seems with these. I can help you get the set working but this fix only prolongs the inevitable so I'm told. (more about that at the bottom) Please read entire posting before starting. You will need to take off the front panel, there are 2 screws towards the bottom on each side behind little pop out plugs. Once those are out take off the panel (pull from bottom, sometimes the round clips at the top come off, either glue them back on the panel or leave them out). There are wires attached to the panel, you can either unhook them or just take them out of the "twist tie" holders and move the panel out of the way to the left. You will now see a thin panel. Remove this one also. Once that is off you will see the bottoms of the 3 glass tubes and on the "floor" of the set there is a group of 6 small knobs. This is called the focus block. Each row of 3 knobs are labeled either screen or focus, also, there should be 3 letters R G B (Red Green Blue). (We won't be adjusting the focus knobs).You will need to adjust the Blue screen knob (on my set it was the bottom left knob). If the set will stay on for a little bit you can adjust it with it on. Once you have found the correct knob (don't worry about the white paint) turn the set on, once you see the picture slowly turn the blue screen knob counter clockwise until the blue diagonal disappear. Be careful not to turn this knob too fast while the set is on. Keep in mind, it may take a little bit to break off the paint. You will see the screen turn back to normal as you turn the knob. Adjust it just until the lines disappear This should solve your problem. If the set won't stay on, with it off turn the knob about 1/8 turn counter clockwise then turn the set on. Once it is on you can fine tune it. Adjust it just until the lines fade out of sight. (You may have to adjust back the other way until the lines show up and then back it off again). Remember to turn the knob slowly. I have heard people getting charged a lot of money for this. I was also told that this is compensating for a dying component(s) all I know it has bought me at least a year. I also read that someone has gotten several years out of there set w/o repair just by doing this adjustment whenever its needed. (once the lines start presenting themselves). I can't see spending big money on these sets when you could put it towards a new set so I will keep it going for free as long as I can. I hope this works out for you. I'm tired of typing so good luck and post if you need any more help. BTW this adjustment works if this symptom presents itself in green or red also. Just substitute the blue knob to the applicable color. Now go put your TV back together :)

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

TV won't turn on, standby light just blinks 9 times


hello, Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

Sony Tv 42" projection tv will not turn with remote or button on front standby light blinks 9 times pauses then another 9 times. When this started we use to be able to continually hit the power button and...


The 9 flash error usually means an issue with one of the power supply boards in the TV. You can verify this by bypassing the shutdown. To do this with the set off and in the standby mode point the Sony remote at the TV and press these buttons in sequence within 5 seconds of each other, DISPLAY 5 VOLUME DOWN and then POWER. The set should turn on with no issues. Once it comes on there will be a diagnosis screen and the bottom entry on the screen should be ZCD. That entry should have a zero in the fail column. If it has anything besides zero then the power supply board is at fault. There are two power boards in this TV so I don't remember which one causes the issue whether its the G1 or G2 board. At this point if this is the issue then I would have a technician do the repair since replacing either board isn't that easy. Please take a few moments to rate my answer. Thank you....

count the flashes again carefully, as that model should only blink a maximum of 9 times, unless your getting two seperate codes. Try counting and trying to notice if it pauses a second before blinking again. then let me know what you discover.
