JVC LT47 that picture goes black (sound fine) after being on for awhile. Can turn TV off, then back on & it's fine. But then happens again about ever hour or so.

I have a 2 year old JVC LT47 TV that the picture goes black, after being on for awhile. Can turn the TV off, then back on & it's fine. But then it will happen again about ever hour or so. Does anyone know what the problem sounds like? A capacitor maybe?

Hello
Hello
It is due to some loose soldering points [dry soldering we say it technically], in the power supply section of the TV. Just check for it. Check the solderings of all components, that will heat up to an extent when the TV works on. Repeated heating and cooling may make solderings to the terminals of that components to get loose. Just resolder all the suspected solder terminals, by applying a little more solder, without making any solder bridge short in between adjecent solder terminals. This must solve the problem to your tV. OK.

My 55ld520 screen goes black, turn off for short time comes back on but then goes black again.


Start simple by using different cables, whether they be HDMI, VGA or standard COAX cables. They could be losing the connection. Also, it's possible the power supply is wearing out and it gets too hot. You might want to simply try some spray air duster type thing to clear out any dust that can make it hot.

Tv screen goes black after 15-20 seconds


It's not the TV from what I can tell. I would start complaining about it and say you want a brand new box. Not used. They tend to give out boxes from people who previously had them and either didn't pay their bill or moved and clean them up.

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 )..............

Looses video


There are so many thing that can cause this to happen. If you answer some questions we can narrow it down some. 1) when the picture goes black if you hit the menu button on the mitsubishi remote or on the front of the tv itself does the menu show up? 2) After it goes dark how do you get it back? do you turn it off and let it sit for awhile or can you turn it off and then right back on to get a picture? 3) what is the model number? this can be found on the back of the set. If you can answer these questions we can go forward.

Thanks!

No picture, sound ok


I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.
