That's why I say people, do not trust power blinks, trust service specialists with experience.

Any short in any board connected to the power supply would result in , well, short at the output of the power supply.

The monitoring logic would, in turn, read that as lack of voltages and would report is as bad power supply.

Except the problem is not in the power supply, but in the external module which has shorted!

I am about to write a short and helpful article now on troubleshooting plasma TV for problems like this; I am about to post it on my blog at www.coppelltvrepair.com .

Hope it will help you!

I have a Sony kdl-46es700 flap screen LCD TV; The picture is black, red indicator light blinks 7 times every three seconds. Have already replace the power board. How do I resolve this problem?


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.

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.

Three Blinks: Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the APh

When power it'll blink three times and shuts off


It is probably the power board. When the capacitors on the board fail they can make a hissing noise. If you look at the board and the small cylindrical things on the board ( which are the capacitors) are bulged on top instead of flat this indicates a failed capacitor. The board should then be replaced. Hope this helps.

RCA61DLP42 rear projection TV displays dim picture for 30 sec with no audio. Then screen goes dark and power light blinks three times. It usually tries to start up again, with the same sequence of events...


3 blinks indicates a failure in the inverter / ballast board. Since you have replaced it it means that the power source board, the one that power the inverter, is faulty and it will have to be replaced.

hi,
You have to check the power supply of you tv for any voltage missing. also check the back light inverter board for any short circuit in it. Inverter transformers in the back light controlling board can become faulty.Three blink indicate the power supply have some problem. First of all replace all the electrolytic capacitors in the power supply board. If filter capacitors in the power supply is bad then this problem can occur.

The tv does not turn on and thepower light blicks three times


hello, the blinks indicate a fualty board or circut if you can find a service manual for your set, you can count the blinks and identify the trouble,
these circuts are working with extreme high heat so they do go bad eventually, so find a service manual and then change the part as indicated in the service manual or have a service tech service it for you that will be a bit more expensive than finding the part and exchanging it yourself but remeber to follow electronic safety procedures as these circuts store high voltages and can be very dangerous,, generally using a service manual will help you pin point the trouble .. hope this helps

When trying to power on it blinks 9times then


Hello: ( 9 blinks on this model indicates an audio problem. Three times indicates you may need service to replace IC501, and IC5002 on the G-Board. It may be better and cheaper for you to just have the G-Board replaced as to replacing individual componets. This is an over-voltage detection issue, and will need to be serviced by an service technician.
