Question about Sony Grand WEGA KDP-51WS550 51" Rear Projection HDTV

Open Question

Sony kdp51ws550 No picture after turning off but sound works.

This problem occured before but after awhile it would come back on. The diagnostic LED is blinking 10 times. I have a multimeter and the back taken off. I have some technical knowledge (low voltage electrician) and can check for continuity, voltage, and resistance. I just need to know what the meter readings should be and where ie should Q8013 and Q8014 read the same? Can anyone help? Thanks, Mike

SELF DIAGNOSIS FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY LED will automatically begin to fl ash. The number
of times the LED fl ashes translates to a probable source of the problem. A defi nition of the STANDBY LED fl ash indicators is listed in the
instruction manual for the user's knowledge and reference. If an error symptom cannot be reproduced, the remote commander can be used to
review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
DIAGNOSTIC TEST INDICATORS
When an error occurs, the STANDBY LED will fl ash a set number of times to indicate the possible cause of the problem. If there is more than
one error, the LED will identify the fi rst of the problem areas.
Result for all of the following diagnostic items are displayed on screen.
If the screen displays a "0", no error has occurred .
Diagnostic Item
Description
Number of times Standby
LED blinks Possible Location

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

No picture or sound, standby led flashes 11 times when first turned on after AC plug has been removed and reinserted into the AC outlet. Every attempt to turn on after the initial attempt yields 6 flashes...


It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The flashing LED is justa coincidence I would think.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Problem for Sony Grand WEGA KDF-55WF655. Hello,


5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?
Thanks.

KDS-R60XBR2 power led blinks 4 times,


There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.

Sony KDP51WS550-LED light blinks 10 times


This is usually a problem on the high voltage board. When you first turn it on, the main board does it's P.O.S.T., then powers the HV board. You'll be hard pressed to find a replacement for it. You MIGHT find someone that can rebuild it, but for the money? Time for an open box special at you local electronics place.

SONY-LED BLINKS 10 TIMES


OK, 10 times is HV protection (High Voltage) and problem can be in D board and Q8013, Q8014 can be shorted along with R8051 open.
also IC8005 can be damaged.
All above parts on D board.
I would recommend to get related service manual for proper diagnose of problem in TV.
Good luck.

Turns on and off green LED flashes until TV turns back on.


this is a symptom of a bad lamp. for some reason it won't spit out a lamp error. shaking up the lamp will sometimes fix temporarily but you will find replacing to be the answer. if your tv has a fan error, you will get 4 red blinks.
