There is a high voltage, and or scan failure. This can be the flyback assembly, and or other support components. If the CRT is defective, it can cause this type of shut-down.

The cost for servicing this would be fairly expensive. It would be best to start shopping for a new set.

The only blinking ligt is the stand by timer a little red light what do i do on my 2005 sony tv when i push power button it goes on then off


There is something wrong with its internal circuit board. These blinking are fault indications; and is called blinking codes. Each and every brand will have a preset number of blinking codes.

Red stand by light blinking continuously black screen


It cannot be reset fully unless it comes on and stays on (the model you have listed here.)

That set should have a blink error code--watch the red power light to see if blinking in a number sequence like 7blinks pause and repeats over and over.

Sony tv will not turn on stand by timer light blinking


Try as suggested to count the blinks to see if it is an error code or not. blinks will be in a sequence with a pause and blink the same number of times over and over.

My sony trinitron xbr tv turns on stays on a few seconds then powers off by its self and it gives 5 red blinks from stand-by


This is according to the sony service manual

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.

Sounds like a failure in the C Board or AKB Circuit.

Best to take it in to a service center.

My Sony KV-36XBR800 will no longer turn on when power is pressed it clicks and sounds like it's turning on but the screen stays black and the stand by light blinks 7 times.


7 times mean no horizontal deflection. So check horizontal output an solder of it and associate parts.Often resistor and transfo driver of base of h. output.

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.

Sonykv-32v40 red ligt blinking black screen and soud good


Take it to a shop... It's a good bet that the jungel Ic, crt driver Ic or something in the HV has failed. Could be also that the crt itself is failing. If that's the case a tech can test it with a B&K and know for certain.
Also, if you want to save a few dollars take it in to them, don't make them come and get it - it just drives the price up for a pu/del charge.
