Look in middle of board for C926 or location like that--it should be 1000 mfd at 35 volts--fails a lot in these sets.

Let me know if you have questions as I am here to help.

JVC flatscreen tv model Number AV-21mt35 with vertical interference? how to solve this problem?


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.

Jvc tv power light keep blinking but tv wont turn on model av 27720


Its power regulator section circuit ahs the fault. If you want to repair this section, you must have through knoledge in electronics and work experience. Most of the components in this section are very dangerous to touch. It is fatal for an unexpereinced one to try to repair this section.
If you are confident, download the repair manual to your set from internet and follow.

Tv has a flat light across the middle of the screen. thats all it will do.


Very common issue is bad connections on the vertical output IC. If you can tap on the main board and the picture starts working or you see it flash to a full picture intermittently then you will need to re solder the IC. The location I believe is IC1421 on it should be near a connector and wires that are yellow and green in color. Please take a moment to rate my answer. Thanks...

Tv wont turn on


This is a general failure indicator and can be anything from a blown fuse to a bad power supply/vertical IC/lightning strike.

There are 2 fuses, check/replace both. if they blow again, check for physical damage to the vertical IC LA7832. If its cracked or had a hole in it , you are going to need to take it in for service.
