SOURCE: power light flashes twice,then opc flashes once then power again

In all the time that you have had the tv have you applied 2 firmware updates that some of the tv's need to avoid other known issues with the lcd in the future. These firmware updates are for the main cpu PH1UU112 and the monitor MD1UA104. I don't know if this is the case for you but it worked for me. Call Sharp at 1-800-237-4277.

Fault protection mode.... More than likely you have blown Uf Caps on the PSB-Power supply board. Recap with new Uf caps. A few bucks, solder and a soldering iron.

SOURCE: No power to tv. Power and opc lights flash twice,

That means you may ahve problem in the power supply or the backlight inverter board. You can disconnect the cable to the inverter to see if the 24vdc comes back on, then you need to load it with 24vdc load that can draw 3~4amp to see if the power supply can handle it OK and maintain 24vdc output. Then you need to check the inverter board for shorts ot burnt out parts.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Final Up date, The TV is fixed, with my problem it was found that the units Mainboard was defective. If you go to replace your Mainboard MAKE SURE THAT YOU PURCHASE THE CORRECT BOARD AND VERSION NUMBER OR IT WILL NOT WORK...... for example KE833 XE833WJ and the most important part, look for the version on the White lable markings, mine was FM11S it will be some FM number that will be used on your Set. Hope this helps you solve your problem.

Hi Tracy,
It appears your TV is not sequencing properly. By the order given in your instructions with the controller you are tuning, continue with a code until it satisfies .


Press setup- blinks twice. Enter TV manufacturer code- press enter. Light should flash once. Press on . After it works . Go through all the functions. Up- Down, loudness, channels,& on -off .


Fare .Well.
