    I had the same TV with the same problem. Replaced capacitors and it has worked ever since. The only way to test a capacitor is to remove it and ise a capacitor tester. Did you do that if not then you can not say that they are fine.

    It was the TV Control Board! The Power Supply was Fine!

I have a 42PFP5332 which doesn't turn on. When plugging in the power the green led on the power circuit board turn for a few seconds and then blinks for 9 times. After that it blinks for 10 times


Good day!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

I have a sony kdl-52v4100 tv. It had a power surge and now blinks 2 times. I changed the power supply with a known working one and it burnt it up. I changed the power supply again and the bu main boar


Those 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.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Hi bschaub796,
10 times blinking of your unit indicated that the processor sense the missing 15v from the power supply. This problem is quite technical since I've already read your post that you have a reading of 15v in P25.
Now, we have to examined it deeply to determine where the fault came from between the two board.
If you have a 15v coming from the power supply but its go to 0v after a while which trigger the 10 blinks, you have to check the feedback circuitry of the power supply for faults. If you can't find any faulty parts on that section means that the feedback circuitry trigger to shutdown because it sense fault in the D board.
Remember that it has a good regulation output from the power supply, the issue here is the feedback circuitry that sense the fault. If you are going to ask my opinion I've suspected that the fault is in the D board.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Wont turn on blinks 7 times


Hi there.
In sony tv`s the seven blinks code(sony error codes)usually indicates a high voltage shutdown(t.v has exceeded 33k volts). That is often caused by the power supply regulation and/or horizontal circuit fault.
Hope this help Merry Christmas
