Have TV Questions? Ask a TV Technician
Hi , I`m Jack , I will be helping you today Can you please send me a reply when you are ready to proceed ?
This is fairly obvious to me that you have broken connections internally and it would be difficult to say offhand if that buzz and the streaks coming out the LCD block are related but i can tell you that you will need a pro to investigate this .
The light engine will have to be pull out completely to check for possible loose or broken connectors or worse broken solder joints.
You can expect a $300 bill in average to have this done at home .
considering the age of the tv and the fact that you can get a new 50" tv (this one is 42")with all the bells and whistles for around or less than $450 ,I would think twice before investing that kind of money into this one.
I think your money would be better invested in a new tv .
