I have a sony tv model kv-27v42 i have sound but no pictture and stand by light blinks what is the problem

How many times do this standby light blinks at a time of switch on? These blinks are fault indications. From the number of these blinks, you can get an idea about the faulty circuit section inside it. Count it. If you wish to get more details about the blinking codes to Sony TVs, check this link.

Sony Wega Kv-36XBR250 screen blinking

I have seen this flashing before, this could be an indication that the picture tube is weak, what happens is that if the white balance is off there is a circuit called akb it monitors the kathode of each gun and if they are not in balance it will attempt to balance it out. if it can't the picture will begin to flash, sometimes in some models the power light will blink 5 times. On some models the power light will only flash if the tv gives up trying to compinsate for white balance and shuts off compeletely. If you see the tv shutting off with 5 blinks then you know for sure it is time for a new set.

Stand by\timer blinks,picture go out everytime it blink .

Blinking codes meaning:

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
Good luck:

Sony Trinitron Color TV KV-35V65 - No Picture, red light stand/by timer flashing

A reset won't fix this. The standby light should be blinking a repeated count with a 3 second pause inbetween. Post that count here. That will indicate the circuit/condition that is preventing the set from turning on.

Timer/Standby light blinks but no picture or sound when power button is pressed.

I'm having the same problem. My stand-by light blinks 3 times though. The tv clicks as if it is going to turn on, but it never does. Is there a simple solution to this problem?

If you have sound but no picture it means that your power supply and tuner are working correctly. The number of times the timer LED blinks is the code for the problem with the picture. The computer will stop the picture and blink the timer LED if the vertical circuit stops working, if the picture tube is too weak or if the horizontal sweep has stopped. The set should be serviced by a qualified tech familiar with Sony sets.

Picture is going fuzzy and blinking red light...

This is the classic symptom of a CRT (picture tube)that is starting do get weak. The picture takes longer and longer to come on, it appears greenish and blurry, and it blinks on and off in different scenes, and when it is off the timer LED blinks 5 times. Sony has a circuit called "IK Blanking" which monitors and adjusts the colors in the picture tube, and shuts the picture off when the tube is getting too weak. The good news is that the Sony tubes always respond beautifully to a CRT rejuvination (recharge), and the picture returns to perfect. Since the set is 36 inches and VERY heavy, it should be serviced in-house and an appropriate charge for a service call for your set should be around $150.
