Possible that the surge had resulted in the SMPS- switch mode power supply - giving a higher output before it would have corrected but had resulted in the failure of some component.
Remove the panel if you can start the work armed with a multimeter, the mains power being put off. wear insulated slippers while probing the circuits specially when the power is switched for voltage checks.
first of all check the main power unit :click for tips on SMPS
If there was no fault noticed visually then check the processor controller section specially the voltage to the processor. If the +5 volt is missing check the regulator or the feed.
If there is power then check if the mP activates the HT circuit, if not the main board had errors to be looked into with a trace of the working voltages, look specially for charred or damaged components.

TV WILL NOT TURN ON AND RED STATIS LIGHT IS ON NO CODES ARE SHOWN. WHAT DO I DO?


If the red indicator light on the front of your HDTV is glowing a solid red, you should first unplug the AC cord from the wall power outlet and wait for 60 seconds before reapplying power to the HDTV.

After you turn the TV on, if it doesn't power up, try holding the power button down for at least 8 seconds. That's supposed to force a system reset. If your model has a system reset button, use that instead. Press the reset button for about 20 seconds...release it and press it again for 20 seconds, release it again and the led will blink just for a minute or two. You should now be able to turn the TV on.
If after several attempts, the HDTV has not fully powered on and the LED on the front of the HDTV is still glowing solid red, you may want to reseat the lamp.

If reseating the lamp has not resolved the issue then your next step is to order a replacement lamp. Keep in mind that some off-brand lamps may only last a few weeks, so replacing a relatively new off-brand lamp may unfortunately be necessary.

Sony KDL 46HX820 turns on, then off and red light blinks four times.


Re: Bravia KDL46EX720. Red LED blinks 4 times and TV wont turn on. What is the problem?

Do a Power Reset.

1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.

If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

I bought my son a 19" philips tv model # 19pfl340d/27.in order to turn tv on it must be unplugged for 10-15 minutes.The first one I bought did the same thing and I returned it.this one is exactly the...


The remote control will not operate the TV when the TV is in the OFF mode (No LED lit on front bezel). To change the mode from OFF to STANDBY or ON, press the POWER button on the side of the TV. Once the POWER button is pressed, the LED will change to either red to indicate STANDBY or green to indicate ON, whichever mode the TV was in prior to being turned off with the TV POWER button.

By pressing the POWER button on the side of the TV, the mode will toggle from OFF to either STANDBY or ON. If the POWER button is pressed and then the LED on the bezel is red, the TV is in STANDBY mode and will need to be turned on using the remote control. If the POWER button is pressed and then the LED on the bezel is green, the TV is ON.

TV Won't Turn On


there is no reset button - the main fuse has probably blown and needs replacing (6.3A 250 V)

Pioneer VSX 915 powe off


Had a power surge last night and got the same problem. Unit wont power on and has a blinking blue light on standby button. I found the solution from the service manual for a similar model.

Hold down ENTER and ADVANCED SURROUND buttons.

This resets the DC overvoltage sensor and bingo the unit comes back to life again.
