CRT Vestel 11AK37-11 trouble shooting

Can't Post

Hello, I am trying to trouble shoot a CRT TV with a Vestel 11AK37-11. It started when Q801 shored in the smps, I managed to get the TV working again by replacing Q801 and the IC800 controller, and also the Q601 HOT. Everything worked OK for a couple of weeks and then static on the screen started randomly. Eventually it go to the point where the TV would jump into standby, finally blowing the Q601 HOT. I have replaced the Q601 HOT again, the TV works powers up OK, but the static seems to be happening again, and jumps into standby. If I leave it running it will probably blow the HOT again. I have check all the diodes and resistors and all looks OK. I don't have any specialised equipment other than a dmm. I have followed all the items on this previous post http://www.tv-forums.com/forum/TV_Equipment_C4/TV_Repair_Forum_F3/CRT_Vestel_11AK37-8_Shorted_HOT_replaced%2C_still_shorted_P161799/ Any ideas what would be causing the static? Cheers
