The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

SOURCE: WONT TURN ON

Most likely, the problem is a defective Main Processor Board. This is the board with the antenna, RCA and HDMI plugs. You cant repair or replace component parts on this board, so dont even try. You must replace the complete board. The TV says Sylvania, but it is a bloody Funia TV. Several years ago this foreign company bought out broke-azzz Sylvania . They are still carrying the Sylvania name since Sylvania was a popular TV name in the 70s. Every electronic company in the USA is now owned by the Chinese, so call Funai and order the part from them. Dont be surprise if they dont have a clue what the heck you asking for. America and all electronics have gone to the puddles. Do you know why? GREED.

Alba tv flashing blue light tv turned itself off


If it turns off after a while that's a transistor going hot.
You need a technician to test it for you. If you want to do it yourself
let me know. Good luck.

Tv wont turn on


Hello Charliebigwh, hi technically your monitor's power supply has a problem, this is either your switching regulator does not work or there is a short in that section, If you want to do it your self, need to replace all large value, and or high voltage capacitors(especially the capacitors with its top is bubbly), need also to replace the switching IC, and power transistor.

Have it checked by a technician if you cannot do the work.
