The speakers of a 55 inch Samsung led tv are suddenly buzzing / rattling above 50% of the volume. In addition, there are some vertical lines left and right of the screen. What might be wrong? Details I own a UE55D7000 Samsung LED tv. Motherboard no UE55D7000LSXXH. Power board no PD55B2_BHS, BN44-00428B Recently both the speakers started to rattle above 30-50% of the volume. Furthermore, I noticed some discoloured vertical lines on the left and right of the screen. I attach a picture of the vertical lines on the right. The picture was taken from the picture test menu (within the tv settings/ support menu). All inputs were disconnected during the test except of the power input, which is stable. Which part do you suggest me to replace / fix? I am grateful for any advice.

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

Don't replace anything, Vizio has issued a lifetime warranty for this set because of this problem. No joke, call the customer service line and tell them you got the pop of death. They'll send someone out to 'repair' the set free of charge. If they can't fix it they'll give you a new one. Even if your mfg purchase warranty has expired. Call them and post the results. I've been fixing TV's longer than I care to admit and this is the first time I've actually seen a company stand behind their products like this. I bought a broken tv with the intent of fixing it and after replacing almost every board I could only manage to get the vertical racing stripe line, except mine was purple. I put it all back together and called to find out if there was a recall on this set and within 5 minutes the (Actual English speaking) gentleman told me to sit tight and he'd have a repairman come and do his thing. He did, and long story short, he couldn't fix it. Last week they delivered a new TV to replace this one. I was shocked. I think Vizio will have all my future business.
Good luck.
