Hi, not sure if this is same fault, but for anyone searching this model, if you warm up the  back of the TV near the top and it starts up ok,  then there's a stock fault  that is fixed by changing the value of a resistor on the PSU board. Don't have details at hand, but will try to dig them out if you pm me.

HI Evan,
Your symptoms indicate that the OTC-supply may be coming on faster than the FBX-supply. At switch-on, the OTC is initialised along with all it's IC2 address to see which components are present. If the FBX is not present at this point due to a slow start, the OTC concludes there is no FBX and sends the set into protect.

A Philips service bulletin suggest the following mod:
On Aux power supply, replace positions 3031 and 3032 with a 27K 5W resistor. So you remove 3031 and 3032 and place this new resistor on posn
3028.
Replace 2002 with a 330u 25V elco and 2003 with a 680u 25V elco. Hope that helps,  Bruce
