IO have no picture but I have sound

A shorted circuit will cause this.

I believe that model has a logic board in it and that is what it sounds like to me. That is just off top of my head, but I believe if you will notice the standby light it will be blinking so many blinks and stop and then blink again. If so this is a code that you can look up on the Samsung web site and plug in your model and it should tell you what just say ~ 4 blinks means. I worked on so many and it has been a while but I believe the last one I had was a Samsung and I put a logic board in it. If I can be of any further assistance please let me know.

How many times do this standby light blinks. It is fault indications. You can get an idea about the faulty section inside the TV, by counting these blinks occurs at one time switch ON. These are called blinking codes. For more details about blinking codes to Sony brand TVs, check this link. Pull up older posts there. Surf the site with patience.

if the standby light blinks 6 times it has a bad backlite board (the most common with that set) other than that i will need to know how many times in a row it blinks. thanks....techman

The light is blinking a repeating error code. Try to determine the number of blinks before a slight pause as that will be an error code. Then respond to this same post and I will assist you with diagnosing what may be causing the set not to power up.

sony KV40XBR700 tv no picture but sound is on, standby light blinks 6 times

Hi,
     According to the LED BLINKING there must be some problem that are given below:

Diagnosis item:  Video out abnormality detection

TIMER/STANDBY
Indicater
Number of blinks:   5 times


Supposed malfunction:  Video out, IC7101, 7201, 7301 and others in C board circuit.

Condition:TIMER/STANDBY LED blinks approx. 30 seconds,
and then blinks for the self diagnosis.

Self-diagnosis
screen display,
Diagnosis item: Results:   5 : AKB 000


So, This was the result of 5 times led blinking.I would suggest you to please contact any expert or strongly recommend to contact any SONY SERVICE CENTRE for repair because it's not an easy job to rectify this problem. Hope you better understand my sayings.

Thank you for using fixya.

 
                                 
                              

Plug the electricity to a surge protector. I fixed my that way. Try it and let us know.

KV32hs500 tv won't turn on. Standby light blinks 7 times, stops and then 7 more times, etc.. The tv will usually come on after about 2 hours or so of being off. Plays fine when on but once it gets turned off the problem happens again. Any suggestions? T.V. is 5 years old.
I have a similar problem . mine blinks 6 times or 7 sometimes also,and comes on with sound ,no picture for about 2 seconds then shuts off. Anything?
