Does the JVC AV-56P776 have any kind of lock out on it went thru setup it plays dvd's but not regular tv


if plays DVDs via rear connections what have you got hooked to it for regular tv reception? Hooked to the coax fitting, using antenna or cable or sat with a box or not?

Good news is if it works with DVD set is likely ok and you have some other issue----just need some more information to decide what that issue is.

I have a JVC AV-65WP74, I went to bed watching the TV then turned it off for the night but the next day when I turned it back on the blue light came on on the TV but no picture, the TV makes a fast...


The clicking you hear is probably caused by a relay that controls the incoming AC to the main power supply. This is a protective reaction to a problem in the power supply itself or an overload due to a failure downstream from the supply. This is not a likely DIY repair. You will probably need a technician to determine which of these two likely problems it is.

It is worth getting an estimate. From the symptom you explained, it looks like the horizontal output transistor became defective.

Clicking and powering off


That's just the relay switch in the power supply trying to come on. Because it clicks right off it sounds like you may have a short in the circuit (power supply or high voltage). Get it looked at by a professional.
