maybe the electron gun had gone south? tube is dead? check with a technician to get full diagnosis. You may still be able to get part if a repair is needed

Hi Rayjanardank
Eht on all modern ctv is generated with in the flyback transformer , although some older tv set use a triplier unit feed with a 8kv pulse from the flyback transforme
To find out the one that you have got , if the flyback transformer as two controls A1 and Focus mounted on it then the eht is generated inside, if the Focus contol is mounted on the tippler unit unit .As you do not state the make mod No of tv i cannot be of any more assistant but you could cheek the A1 voltage on the crt base , if this is about 350/430volt then the eht should be ok. Hope this might help with your problem.
Regards windyhouse.
