If it turn off after sec then go to red light then it is common power supply board, but you need to check all your board fusees then look at all capacitors if it blown then replace it with the same type but when the board out the TV and be very careful for power , also get another opinion. good luck

good luck

My sony kdl 46 turn on tv green light for few sec then stnby light flashes 2 times , what does that mean


I checked on the schematic, there is a self diagnostic mode for the tv accessed with the remote control. If the TV does not turn on I would highly recommend finding a local reputable service facility as this might be completely a fault inside the TV. https://www.encompassparts.com/shop/model_research_docs/?file=/SON/sm/KDL46V4100.pdf

Please check page 12 for self diagnostic procedure.

Hi Mizanur,

First of all, thank you for posting your question here at Fixya.

Your TV has a built in self diagnostic software that can help us diagnose accurately where the fault came from once the unit gone to malfunction. To activate it, press the following buttons on the remote control within a second on each other in standby mode( red LED is on), "Display", "5", "Volume (+)", "Power". Initial screen will be displays as follows :


12_14_2011_11_31_03_pm.jpg

To display the self diagnostic list, press12_14_2011_11_34_30_pm.jpg on the remote control.

The screen will display the list of error log as follows :



12_14_2011_11_36_32_pm.jpg
Numerical value "0" means that there's no error detected, "1" means that an error was detected.

Please let me know what error code(s) with numerical value "1" to continue our diagnosis.

Kind Regards,

Jdvillanueva

Im having a problem with my TV turning off and the standby button flashing 7 times, after it shut off. What can I do.


hi,
Blinking led in sony tv is its self dioganising function. 7 blinks by it means the horizontal output voltage increased above 33k.
You have to check the power supply stage of you tv. Normally in sony tv dry soldering can happend in the power supply stage. It will lead to unregulated voltage output from the power supply. Resolder all the points in the power supply section it will solve your problem.
ok

Sony lcd wega KLV-30HR3 Tv turned off wont come back on standby light keeps flashing in intervals of three


Your TV needs to be repaired. The blinks are a self-diagnostic function built in to Sony TVs. Three blinks may indicate a power supply issue.

KDF-46E2000 turns off then back on by its self


* Most common would be a couple of capacitors in the power supply that are not letting the proper voltage to the lamp.
* The lamp itself is not working properly.

Solution is simple....

First, unplug power cable from the back of your TV. You will notice the flashing light is still flashing. Don't worry, go to the Second step.

Second, keep pressing on the POWER button, located on the panel at the top of your TV, to shut off your TV. This will stop the flashing light from appearing.

Third, Plug the power cable back onto your TV

Fourth, press the POWER botton ONCE, using the same button used in the Second step to turn your TV back on.

Fifth, you will see the POWER light comes on, as normal.

Sixth, using your remote control, press the green button to turn on. Your TV should work as normal.

Power on problem


Many of the later model Sony TV?s have a built in self-diagnosis function. AKB circuit (automatic kine bias), the timer/standby indicator blinks 5 times for about 30 seconds then goes to the self-diagnosis function. In other words, the IC chips on the Cboard are burned out. This repair is not one that should be attempted by the end user. This repair will need special test equipment. You will need to take it in for repair. It shouldn't cost more than $170-$200. This is cheaper than a new TV set.
