Re: philips 60 inch projection
The I2C message that you get means the Inter IC communication bus on the system board has gone bad. Replacing the IC would not solve the problem.Philips patented this technology to reduce the number of ICs on the systemboard.There would be a physical I2C chip on the motherboard.
You can read about the technology on the post by philips http://www.nxp.com/acrobat_download/applicationnotes/AN10216_1.pdf
I would suggest update the firmware on the board, or try replacing the I2c interface controller chip.

The boards are the AC main filter (power Board) The LSB (large signal Board) and the SSB ( small signal board) Which board are you requireing? Let me know which one and I can assist you with locating the board you need.
This model had a lot of odd problems including loss of audio.
With back off as you look from back are three large circuit boards.
One on the far left has another board about 4X5 inches plugged into it at the left rear corner.
Every one of these sets, that is the bad board--controls audio, remote and many other things. Large board it is plugged into is called Small signal Board (SSB), small one is small signal module (SSM).
It is plug in board held with two metal tabs at either end on bottom, It will have printed on it a part number (usually on a white label) with the part number, popular one ends in 2581 but are variations.
Last time I used one it was about 100 exchange(they are all rebuilt boards now)
Ten minute task to replace with back off and 95% chance it is your problem.
Everyone of these sets with no sound or intermittent sound, it was the problem.
You will need to purchase the small signal board......they are kind of difficult to remove and replace. They sometimes look like a small aluminum sandwich box or they look like a video card out of a computer. Read the instructions to replace and reprogram this. Look up at the Philips Partstore.com. Type in model # and see small signal board......These canbe pricey $$$$$$$$
Audio amps in a Philips PTV is one of the easiest sets to repair. To my knowledge all the individual parts are still available so I see no need to replace the entire amp. know what problem you have first, then we'll try and determine what you may or may not need? They had a board which is called the SSB ( small signal board ) that used to go bad creating similar symptoms like that. That board is the size of a 3x5 photo and stands up on the left side of the chassis, anyway let me know?
OK, friends. Time to fix it !!. Replace two Ic's Stk 392-110, and get in service menu settings , and adjust point by point. After replaced stk IC's, check if any resistor look brown or born, if yes, replaced it with 6.8 Ohms.SOme time SSB is defective ( small signal board, replaced it ) If you have questions? email@example.com . Good Luck !!
