Losing the picture

I have a JVC AV27BX4. When turned on the screen is black and has a
white line or it starts rolling. When I hit it on the side the picture
comes back. Not all the time does this work. Can you help me.

Thank you,

I had the same problem with my TV. It is some vertical modulation issue. You will need a tech to replace the chip or board that has the problem.

Unfortunately, this is going to cost you a tech visit or you will need to bring the TV in to a shop, but it is fixable and the picture will come back.

It has to do with the age of the TV.

The controller board for the screen is going bad. check shopjimmy.com for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.

hit your TV lightly on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some TVs on main board ( also on CRT circuit board ) at some soldering joints crack develops....then due to loose contact picture becomes small in size or abnormal width, or rolls etc ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears normally for some time............so solution is .....TV main board & CRT circuit board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again ................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer ........good TV service engineer will charge very less ...absolutely there is no need for new TV........if soldering joints are properly soldered then your TV will work for 1 more year ( minimum )......iam from bangalore - 09986222774 - sathyavijayasarathibabu@ymail.com ( computers, laptop, printers, etc )..............

Screen turn green tv is 57 rear projection


Good Day,
It appears that you may have a green drive issue. Try adjusting the Sreen Control it is located in the front of TV.
1) Remove Speaker Grill (it just pulls off) start at one end, 2) Remove cover (5-6 screws), 3) Adjust control. The control is located on lower right side towards bottom. A small black device with 2 rolls of controls, adjust the center control on bottom row counter clock wise, until you get a black and white picture.(adjust with color control to min).
If this does not work you light bulb (CRT) is bad about a $750.00 repair.

Good Luck, Big Irish.

My JCV av-65wp55 I have a issue when I turn it on it works fine for a while then the picture startes rolling with lines going accross the screen. I can turn it off and wait a while and the picture comes...


A number of this type of JVC projectors had issues with defective soldering to a large capacitor on the pc board in the power supply which could cause such an intermittent prob. Some models also had a similar issue, but one lead of the capacitor was actually broken when inserted at the factory. You would need a tech to look at this, unless you are capable.

Put an used casette inside; hit PLAY and then FFWD until you start seeing images. Eventually you will start seeing some with lines and then the black lines will get smaller and smaller until they turn into grainy lines. Stop and PLAY again and they will faint. RWD and PLAY back as you wish and it should be find. I think this is because of tiny dirt particles that your cassette will dust off for you.

Don't worry you dont have to buy a new camera :) When you press the menu button there should be an options menu. look around for the "effects" options or something along those lines. There is a black and white mode on the camera, my guess is that it turned on somehow. All you gotta do is turn it off.

I hope that this helps, feel free to ask more questions. I have a jvc video camera just like this one, so if need be i can just look at mine!

Theres a line threw my tv.


It has a problem in the vertical sweep circuit that puts a nonlinearity in its output and you see the glitch in the normally gradual sweep as a line. Since a hit upside the set seems to help, you should just resolder the whole vertical circuit area (doesn't take long) and see if that cures it. If not, start replacing the electrolytic capacitors in that area.
Hope Ya Fix It!

JVC A56P575


In the customer menu page thru it until you come to a page that has an item called convergence. move the cursor down to hightlight this and press enter. The next screen will have an Auto on the top line and a Manual of the second line. Hightlight the auto and press enter. The TV will attempt an automatic convergence alignment. BE WARNED>>>It will either correct it or make it worst. If it gets worst then the TV's convergence circuit has aged and is starting to fail. If it corrected it it's the same aging but not as bad, YET. If there is no change or it got worst then you will need to have the TV serviced preferbly by an authorized JVC service center because they have access to the service literature and buttetins.
