While traveling from oceanside (L32) to vny via V23 and receiving traffic advisories from coast TRACON I asked for a TCA clearance. It was denied. I then determined to go around the east side of the la TCA via the 25 + DME arc of lax VOR at 4500'. I contacted ont TRACON (no handoff was provided). I was advised by ont (125.5) that I was inside the TCA. I advised ont I was 25.2 DME (outside the TCA 25 mi boundary) and immediately turned east to 90 to 26 or so DME. At no time was I less than 25.1 DME. This lack of coordination and service between coast, la and ont tracons once again points out the need for VFR routes through the TCA. At 140 KIAS there is little time to stand by and hope for a TCA clearance. Callback conversation with reporter revealed the following: VFR corridor over lax now reopened which will do away with the circumnav problem. Reporter feels the ont radar map was off but realized he may have been cutting it too close to allow for DME error.

Title: GA SMA SUPPOSED UNAUTH PENETRATION OF TCA.
Narrative: WHILE TRAVELING FROM OCEANSIDE (L32) TO VNY VIA V23 AND RECEIVING TFC ADVISORIES FROM COAST TRACON I ASKED FOR A TCA CLRNC. IT WAS DENIED. I THEN DETERMINED TO GO AROUND THE E SIDE OF THE LA TCA VIA THE 25 + DME ARC OF LAX VOR AT 4500'. I CONTACTED ONT TRACON (NO HDOF WAS PROVIDED). I WAS ADVISED BY ONT (125.5) THAT I WAS INSIDE THE TCA. I ADVISED ONT I WAS 25.2 DME (OUTSIDE THE TCA 25 MI BOUNDARY) AND IMMEDIATELY TURNED E TO 90 TO 26 OR SO DME. AT NO TIME WAS I LESS THAN 25.1 DME. THIS LACK OF COORD AND SVC BTWN COAST, LA AND ONT TRACONS ONCE AGAIN POINTS OUT THE NEED FOR VFR ROUTES THROUGH THE TCA. AT 140 KIAS THERE IS LITTLE TIME TO STAND BY AND HOPE FOR A TCA CLRNC. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: VFR CORRIDOR OVER LAX NOW REOPENED WHICH WILL DO AWAY WITH THE CIRCUMNAV PROB. RPTR FEELS THE ONT RADAR MAP WAS OFF BUT REALIZED HE MAY HAVE BEEN CUTTING IT TOO CLOSE TO ALLOW FOR DME ERROR.
