SHARP TV MODEL LC-46LE830U WILL NOT TURN ON. I HAVE REPLACED THE POWER SUPPLY BOARD WITH NO HELP. IT HAS 2 BLINKING LED LIGHTS FOLLOWED BY 5 BLINKING AND REPEATING AGAIN. WHAT IS MY NEXT STEP?


It sounds that the main board fitted with your Sharp television is of Philips. Those blinks are fault indications, and you should follow the procedure of counting the number of blinks, as you do with Philips brand LCD TVs.
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.

Philips 40inch LCD 40PFL7705DV/F7 When connected to power, it tries to crank for 15 sec and turn off by itself. This repeats. Back light is on while it tries to turn on.

Looking for a lcd screen replacement procedure for Toshiba Satellite L305-S5957.


If the screen is not physically broken then the fault is most likely a back-light problem. A back-light problem is usually caused by a faulty inverter or a faulty CCFL lamp. These components are a lot cheaper to replace than the whole LCD screen.
