Here is a question that we see often.

Question:
I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ?
So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what is does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part your put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'No Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous use it as an excuse to get money for selling items that may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $2 parts and an hours labour.

A temporary fix to the problem is to put the battery in the freezer for a minute and then put it back in the phone and it will turn on just fine! I had an LGVX8700 and it just randomly started happening one day and my fiance told me to try doing that so i did and sure enough it worked. I had to go to verizon at one point to get a new phone because the one i had got damaged and the tech there used the same battery in my phone for the new one and he thought i was crazy when i told him to put the battery in the freezer but he was in for a surprise when he did what i told him and my phone turned on. It's annoying because you have to do that everytime your phone shuts off but i always made sure i plugged it into the charger before it went completely dead.

There is a capacitor on the rear of the display, you need to replace the capacitor or just buy a new display module.

It will most likely go away when you fix the board. I suspect there is a logic system in there looking for that port and is not finding it.

Bonjour,
Il se pourrait que le haut-parleur aussi bien que l'?cran ait besoin d'?tre changer , toutefois , il est toujours plus judicieux de demander l'avis d'un sp?cialiste. J'esp?re que ceci vous aidera

If you know how to access the region code, then I suggest you give it the code for "0" then you will not need to change it again. It should play back all.
