Nowadays to repair the LCD or LED TV is not so hard to compare 3~4 years ago. But when the LCD/LED TV problem is causing by their screen problem (some will call it as LCD Panel), most of them are beyond repair or not worth to repair it. Because the new LCD Panel price is quite expensive and nearly the 70~90% of new TV price!  

From these past years, I found out that SONY, TOSHIBA and OEM brands LCD/LED TV having lots of display problem and it is because of the Panel failure. And this Panel fault was causing by a “branded” Panel manufacturer! (Here I don’t want to write which company…  J).

They will not accept this TV into their workbench and ask customer take it back and don’t want to waste time to repairing it. Even the repair shop or repairer received call from customer with explain their TV symptom is screen problem, they directly tell the customer it's not worth to repair and better buy a new TV!
