Open Question

Kdl-46z4100 standby light blinks 14 times

TV started with getting a random "Green" screen that could be fixed temporarily by changing the channel and then the "Input". Then back to the input you were on. Weeks later the problem changed to "Standby light blinking 14 times at power on". unplug tv and reset and it fails on power up with same "Standby light blinking 14 times".

SOURCE: My flat screen tv shuts off and standby led blinks 13 times.

Our $2700 less than 3 year old Sony LCD KDL-40XBR5 did the same thing 2 weeks ago. Sony was anything but helpful. They said to take it to a repair shop or we could send them $550 and they would replace it with a $800 set. Repairman says that it is a panel and the part has been discontinued by Sony. The 46" sets had the same problem and were recalled but not the 40" screen. We stopped on the way home and purchased a 40"

SOURCE: Sony KDL-46z4100 standby light blinking 12 time with few seconds gap continiously

12 blinks of standby light indicates 'Scanrate error'. You must have thorough knowledge in electronics to proceed. Actually, this is not a user repairable fault. it is very skilled work.

Sony KDL-52w5500 black screen 13 blink then 14 blink


You have a couple of problems if you are sure there are 2 different blink codes. 13 blinks indicates a backlight balancer error which would explain your no light condition. 14 blinks would be a TCON board error which is the driver board for the LCD screen. Either error would keep the screen black.

Hi, Sony kdl-46Z4100 - no standby light when


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; [Exclude the model number], in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sony xbr6 standby light blinks 14 times, pauses and repeats


Just count the number of blinks occur at one time. 14 blinks to trinitron TVs are not possible. It might be 10. If so,
  1. Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board. If you wish to know more about blinking codes to Sony Trinitron models TVs, check this link. If it is 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, volume 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 problems named, are 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.

KDF-50a12U Powers off then standby light blinks 3 times


Please recheck Lamp Cover and make sure it is fixed in its space securely as 3 times red blink shows lamp cover error.
There is small safety switch in TV cabinet under lamp cover that has to be pushed by lamp cover if it is fixed in its position properly. That switch is not being pressed by lamp cover and causing this error.
Thanks.
