Hello, I have a LG TV model 37LV4500. Its power light is blinking but no sound and no picture. Please help me with any advice?
Call customer service in your TV book that came with the TV. They will find you a repair shop near you to get the part you need to replace. If it is not replaced it will eventually burn out and the TV will not work at all. I hope this helps, I had similar trouble with mine, had to replace the part. It eventually went out again so I just tossed the TV and bought another. I got 5 more years of use out of the first replacement part.
If you need a tech service, I can suggest you these guys www.tvrepairjacksonvillefl.com but you should search the best option.
don't try to fix it alone
Well I guess you have warranty and you can just take your TV to the manufacturer. If you do not have warranty you can find professional technician. If you want to repair it by yourself you can browse for tips on repairing TV. i can suggest you some:
