Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

pls tom66 you have answered this
I think firmware may be corrupt, no reset will cure that. The "I2C" method may be necessary
how to do that I2C method

Re: sharp_lc32ga9e wont power on

You can probably try this method. On the Main Board search and locate the EEPROM IC. It would be an SMD 8pin IC SOP-8. It will be the 24C64, 24C128 or 24CXXX ICs. (I did not look at the SD for this TV)
Look up your EEPROM IC number and determine the pin configuration
Five (5) easy steps
1. With the TV OFF solder a jumper across the VCC pin and the SDA.
2. Power ON the TV for 20sec. (You may see an error message on the screen)
3. Disconnect the jumper at the SDA pin and switch OFF TV.
4. Remove the other end of the jumper from the VCC pin.
5. Now power ON the TV, it should perform normally.
