CRT_Fan;... Good show,that's progress... ""Any more tests I can run in the meantime?"" No... ""If the flyback is bad, do you think it will take out the HOT and power supply transistors again?"" Most likely , yes.. IF you hear a "POW" , then most likely power supply is toast again... Just be quick with the AC cord, VERRRY QUICK !!!.. Just curious... Was the HOT physically damaged when you took it out ??? While waiting for the new HOT , check around the top area of the flyback for any signs of arcing , burn trails etc... Look into the gap area at the core for any signs of arcing... Take a close look at the thick red wire coming out the top for a pinhole that may have a slight burn around the hole.. Usually about 2~5 inches above the top of the flyback is where that occurs.. Also take a close look at where the red wire goes into the CRT.. Look for a burn trail coming out from under the rubber cup ^^^ to the gray coating on the side of the CRT... IF you see ANY indications of arcing or burn trails , flyback will be bad.... EXCEPT for the rubber cup.. That can be replaced.. When you get the new HOT & install it , do the following;=>.. Presuming you did NOT hear a loud "POW" , let the TV run for 15 seconds & turn it OFF ... Unplug the TV & using a finger , test the temperature of the HOT by placing your finger on the number side of the transistor... If it is warm & NOT hot , repeat the test & leave the TV on for 30 seconds.. If it is warm & NOT hot , repeat the test & leave the TV on for a full minute.. If it is warm & NOT hot , repeat the test & leave the TV on for 5 full minutes.. Check it again... If it is warm & NOT hot , repeat the test & leave the TV on for 15~20 full minutes.. Check it again... If it is warm & NOT hot , chances are that the flyback is good & the subbed HOT was the culprit ....... I'm NOT a fan of subbing flybacks no matter how good they are.. Always seem to have side effects.. Not worth the savings you get.. IF you can afford it , I'd recommend you get the original... Merry Christmas to you & your loved ones also... Later...Ron.M.....
