Before go, the standby/power LED will blink to a certain times, and these blinks are called blinking codes, and are fault indications. From the number of these blinks occur at one time switch ON, you can get an idea about the fault circuit stage inside the TV. If you wish to get more details about these blinking codes, check this link. if you're sound in electronics, you may get it repaired by yourself.http://electronicshelponline.blogspot.com/
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

SOURCE: Sony Trinitron Wega kv-36fs120 wont turn on, standby/timer LED flashes 9 times.

1. Place set on flat solid surface (garage floor or driveway).
2. Bang into it with SUV 3 or 4 times.
3. If set fails to respond, crush against garage wall or drive over it

My 15 month Celcus LCD423D913FHD tv will not turn on. The standby light is lit and will flicker but will not power up the tv. What is the likely problem?

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Sony KDL-32S3000 BLINKS 5 TIMES STUCK STANDBY MODE

Remove all speaker wires and try again. If it unlocks one or more speakers are bad. If not service required for amp. Good luck.

Sony Bravia KDL-55nx720 My tv is stuck in standby mode. Blinking twice.. Would replacing the power supply possibly fix this problem? Please help.

Normally yes. Blinking twice is power protection trip. Look first for open resistor, broken fuses (and short circuits or broken transistors / ICS if thats the case).

I will need the model number of the Sony and also how many times does the light blink? Thats an error code so the number of blinks will be linked to a specific area of the TV having an issue.

Standby LED blinks 4 times

Hi there,

4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.

Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.
