Set won't turn on

Excepting the obvious (you have power from plug CHECKED / you'd be surprised)

MANUALLY try power button / to be sure remote isn't faulty.
There should be some kind of indicator led that set has power.
IF NO lights/ indicator good chance the Power Supply has suffered .. maybe replacing
IF lights but still wont start
Likely the "main" board is bad. (other boards or panel can also be an issue)

Have you checked the various power supply voltages?...are they all correct?

how long have you waited since it shut off? it may be overheating. if you've waited for a while and it still won't power up, you may need to test the power supply. if you don't have a power supply tester and most people don't you can remove it from the case and take it to any pc shop. they may charge you a couple bucks but most shops won't do that. if it's bad it will need replaced obviously, if it's not let us know :)

Good day!!!!

If you hear a clicking sounds of relay inside that means your TV have a voltage on the power supply section.However,when the high voltage attempt to switch the voltage will dropping down and the TV won't turn ON that,s why you hear a HV (high voltage) charge or what we call HV (high voltage) oscillation..

That problem is commonly cause of faulty capacitors on the power supply section..You can easily identify the bad capacitors if it is look like bulged/dome or sometimes leak in oil but not all faulty capacitors have an obvious indication like that because sometimes faulty capacitors look like good but the actual capacitance value change its either lower or higher than the original capacitance value.In that case you a special tester called capacitance meter to identify the faulty capacitors..

This is the sample image of bulged/dome capacitors.


Please let me know if you found any bulged capacitors on the board..If that so kindly replace it only with same type,ratings and value..You can buy it locally or online and if you want sir I'll be the one search it online just give me the value ex.2200uf/50v. uf-means microfarad and v is for voltage..

If you can't find any bulged capacitors let me know,maybe that is time to proceed for advance troubleshooting.In that case you will need a multimeter tester for voltage checking..in this stage you need a moderate technical skills to perform this kind of troubleshooting this stage not advisable for the non-pro so let me know if you have any electronic background..If you don't have electronic background as much as possible I can't advice that because its too dangerous..I can diagnose the problem base on what you see and observation..

Just keep on touch!!!!

Hope it helps..

Try to watch this video on how to replace bad capacitors..

Possible failed video card. 3rd LED indicates MLB and GPU are communicating: (CAUTION! There is high voltage from the powersupply so any attempt to open iMac other than removing glass panel to see the indicators...should be done by authorized ACMT)

• LED 1 - Indicates that the trickle voltage from the power supply is detected by the main logic board. This LED will remain ON while the iMac is connected to the AC power. The LED will remain on even when the computer has been shut down or put to sleep. The LED will turn off only if the AC power is disconnected or the power supply is faulty.
• LED 2 - Indicates that the main logic board has detected proper power from the power supply when the computer is turned on. This LED will be ON when the computer is turned on and the power supply is working correctly.
• LED 3 - Indicates that the computer and the video card are communicating. This LED will be ON when the computer is communicating properly with the video card. If LEDs 1 and 2 are ON and you heard the startup sound, but LED 3 is OFF, then the video card might be installed incorrectly or need replacement.
• LED 4 - Indicates that the computer and the LCD display panel are communicating. This LED will be ON when the computer is turned on and video signal is being generated. If the LED is ON and there is no image on the LCD display panel, the LCD display panel or inverter might be installed incorrectly or need replacement.

Have Capacitors checked in the power relay circuit, also if you have young children who like to push the buttons on the front of the set make sure none of the buttons are sticking inward or stuck in a pushed in posistion. More then likely it might be caused by a faulty System control board which we call the signal board, or bad connections on the power supply, Have a tech check the connections on the Flyback transformer and the High Voltage Deflection Area on the HV Power supply. I believe you have Cold Solder Joints in the HV Power Supply.

Hope you this helps you..

With both of error codes flashing, the problem is trying to figure out wich one to focus on. The flashing 6 code is an indication of HV failure which would then cause a vertical failure(4 blink code). There are so many things that would cause this problem. I can narrow it down to the "D" board to fix your problem. If I were there to troubleshoot it, I could narrow it down further I.E. flyback, HV distribution block. I suggest getting a tech diagnose the exact problem. I wish I could narrow it down better for you. Please take time to rate this solution and if I can be of further assistance, let me know

The power supply, and or one of the circuit board is defective. The set will require shop service.

The led code indicates vert failure for one. ( 3 blinks )
The 2 blinks indicates excess beam current of which could be your picture tube or re-adjusting the G2 voltage on the HV transformer which is very critical on philips sets.
