Its a back-light problem there are a number of boards including the back-lights themselves that can cause thisand there is a procedure to follow if you think you can do the work yourself please let me know but please bear in mind it is possible the back-lights themselves have failed and that is a no go

if u can guide me to fix that please .do I need any replacement parts???

TV Technician: Anthony_Infotech, Technician replied 3 years ago
There is a procedure its not a case of advice on parts there are 3 or 4 boards in the frame and the back-lights themselves so a procedure of observation and taking voltages with a meter are required do you have a meter?this is before deciding which board is bad

Let me know please

Customer reply replied 3 years ago

yes I do

TV Technician: Anthony_Infotech, Technician replied 3 years ago
The first check is if the back-lights come on before it shuts down to 6 blinks so you need to get the set into a darkened room and note if you see the screen illuminate or has a low light just before the 6 blinks starts from switch on let me know please

do u mean I have to open the back of the tv ?

TV Technician: Anthony_Infotech, Technician replied 3 years ago
No not right now I just want you to observe the screen in a darkened room switch the set on and note if you see the screen light up BEFORE the set shuts down to 6 blinking lights.

Later though the set s back WILL need to come off and checks made with a meter (volt/ohms/amp)

no it doesn't light on at all

TV Technician: Anthony_Infotech, Technician replied 3 years ago
OK now you do need to get the back off and a measurement taken of 395vdc across a capacitor on the G5 board so are you able to do that?I will provide more info

the tv is mounted to the wall it will take a while for me to put it down and do the measurements so if u can please tell me what do exactly and the steps that I have to follow and I will take my time to follow them ..thanks

TV Technician: Anthony_Infotech, Technician replied 3 years ago
OK I am just getting information for you please just give me 5 mins

ok sure take your time..and just to clarify what did u mean by( it is possible the back-lights themselves have failed and that is a no go) ,do u mean it can not be repaired ??

TV Technician: Anthony_Infotech, Technician replied 3 years ago
OK when you get the back of the set off look on the powerboard (G5 board)for CN6500its a socket/plug in the top left of the board as you look you need to set the meter to dc volts 500volts and measure across this plug/socket with the set on, the next move is decided on the result of that check.

Yes if the back-lights themselves are bad its a no go and the set cant be repaired economically I must add that in 60% of cases that is the result with sony
