It will be best to replace its Line Output Transformer [LOT]. It is not good to join the broken EHT wire. EHT arcing cannot be stopped by using glue.

The vertical ic of my jvc tv model no. av f21mx5 are always burn even i replace a new one

Just check the supply voltage input to the vertical IC. If it is more than normal, this type of fault can occur. Just compare this voltage . The TV schematic will help you to find this detail. Check whether the IC is firmly screwed on to its metal heat sink.

Hello
Your TVs power supply regulator section has got some trouble with it, that is why power indicator doesn't light up. You have purchased it only fourteen days back, surely there will be warranty for it. Do not open the TV. The company will give no concession if the set is opened. Send it to the authorised service center and get it repaired. Some power supply faults may fatal, and may have to spend more. Since your TV is a new model, spare part availability in the open market may be difficult. Send it to them and let them do the work. OK.

TV: bright line across black screen for several hours.

vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

civilman, the first set has either no high voltage or is collapsed vertically, until someone checks for high voltage there is no concrete answer, the AV27730 is vertical collapse from your description, either the voltage to the vertical IC is missing or the vertical IC has failed, not a big deal cost-wise, hope this answers your questions, if not e-mail me back, good luck, BMW Rider
