Sound like you have a cold solder joint in the power supply section. If you are familiar at all with soldering you may be able to repair the unit. If you are not a tech I would suggest letting one take care of the problem. If you cause a solder bridge in the circuits, you could cause catastrophic damage.... Have you tried hitting the side of the tv while it is having problems coming on? Sometimes lifting the side a fraction of an inch and dropping it, just enough to jar the unit, can show loose connections. If it works then this is definitely your problem. Modern solder systems just don't always get the job done correctly..

Stand by timer blinking red voice no picture


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/

you have a very unhappy tv...sounds like you have a relay clicking, or worse, something about to fail. the led pulsing is a warning signal, and going pure red means that you have a major failure inside the box.

you doing the service yourself, or open to a service pro coming in for this?

When I turn the set on green leds appear for about 30 sec then it swicthes to red stanby and flashes 5 times intermitently


Hi,

May I know what is the exact model number of your TV, it is located at the rear cover, manual, and on the receipt. It will help diagnose accurately where the fault came from and confirm the blinking error code.

TV Sony KV-29F1E turn-on failure, red standby LED flashes (starts after 10-20 attempts)


When the set ends up flashing the LED, it should be a repeatable count. Can you please report that count here? Also, since the set eventually works, I'd suspect a bad connection or a part that has changed value over time. The blink code will help to narrow down the offending circuit.
