The picture has gone black..sound and power are still

Customer Question

The picture has gone black..sound and power are still perfect.
JA: How long has this been going on?
Customer: Just this morning. When I turned it on no picture just black screen. It was fine when I turned it off last night.
JA: What's the make and model of your tv, and has turning it on been a problem in the past?
Customer: I don't know the make & model. It's a 32 inch screen about 5 years old. Never a problem prior to this.
JA: What troubleshooting have you tried?
Customer: Turning it on and off..checking connections and plug ins.
JA: The TV expert can solve this for you. Anything else you want him to know before I connect you two?
Customer: no thanks

Hi , I`m Jack , I will be helping you today
Can you please send me a reply when you are ready to proceed ?
Note that I need time to type and research for parts and info if needed so don't be surprised if there are delays between replies
Also ,Can you please give me the tv`s model number written on the back cover ?

Doesn`t happen to be a LG tv is it ?

Expert:  Jack replied 1 month ago.

Model number will be written on the back cover and brand at the front usually but only the model number will suffice

It's mounted on the wall so I can't see it or get to it but I must have done something when trying to get to it because now my sound is gone too. It's been mounted on the wall about 3 years with no prior problems.

O.k and does it still turn on/off ?

Expert:  Jack replied 1 month ago.

Is the screen just blank with some background light or completely dark like when the tv is off ?
If you`re not sure then darken the room and turn the tv off and on again while you observe the screen .
Can you see the tv`s own menu for example ?

Customer: replied 1 month ago.
The green light in the lower right hand corner comes on. When I turn the tv and wall mount to the extreme right I get the sound back. When I straighten it I lose the sound again
Expert:  Jack replied 1 month ago.

For the sound you may have a bad connection /cable but right now the picture would be the first thing to look at .

Try the TV's own menu , does it come up ?

Customer: replied 1 month ago.
Now I have sound again. It came back after turning it off then again

Customer: replied 1 month ago.
No. The set up function doesn't show at all. The screen is black
Expert:  Jack replied 1 month ago.

O.k then in that case , never mind the sound and the tv will have to come down the wall anyway if the next procedure does nothing ;

Unplug the TV's power cord and hold the power button directly on the tv ,keep holding it for 20 secs or so then let the tv sit unplugged for a couple of minutes before you try it again.
Although i do not expect much out of this procedure , it has to be done to confirm that this problem can be cleared or not with a reset.
If that does not do it then we are looking at internal problems with the tv.

let me know how that goes.

Expert:  Jack replied 1 month ago.

In case of internal problems then you would most likely be looking at a backlight inverter or led driver board failure in which case the only way I see this being worth the repair would be if you do it yourself.

I mean that I cannot see paying some $150 to have a shop repair it while you can get a new 32" for less than $200 nowadays.

Let me know about your ability to perform the DIY repair and with th model number I will be able to tell you the cost and where to buy the correct parts
