Your TVs anode cap is arcing. The sound you hear will be like "Ishhh", and a fouling smell of Ozone also be there from the top back side of your TV.. It will stop after some time, say after 10 or 15 minutes; and picutre will be oke thereafter. You must get it repaired without any delay, otherwise the final anode will get rusted, and will turn the picture tube irreparable.

The final anode of the picture tube is clipped into and is protected by a rubber ******, called anode cap. When the the humidity in atomosphere increses, the arcing also will incresae, and will take much time to get picture to come clear. Anode cap is a replaceable part, even though it is integreated with Line Output Transformer. Proper care must be taken when replacing it, and must be done by a well experienced technician. Do it atonce as fast as you can, otherwise thigs will go worse. The anode voltage of a 32" tv comes upe to 28,000VDC [28KVDC], so it is dangerous to handle by yoursef, if you are not experienced. The charge at that point will hold over for hours, even after the set is switched off. Anode must be well discharged before handling the anode cap. A well experienced on only can do this. Do it without any delay I advice you. OK.

Having trouble getting oil cap of engine.

THis can be a little hairy, but use a big screwdriver or a cold chisel and use a hammer to tap the screwdriver on the right side of the cap, turning it counter clockwise. Let me know if it helped. Oh, and then be sure to lube the mounting area when you put it back on.

CRT TV Screen Colors Off

The tv needs degaussing (demagnetizing) unplugg the set tonight and then plug it and turn it on in the morning. You should hear a a "bonk" noise when the set is first turned on after being cold- this is the internal degausse circuit working and it should fix your problem if you don't hear the "bonk" sound or it does not fix your problem call arepair shop to have the degausse your set and possibly fix the internal degausse circuit.
