Check Streamline Systems they should have Denon. Sound and security should also have Yamaha.Humes wrote:Folks, recommend me a decent 4K receiver that I can buy locally. Might not need speakers, as my Onkyo set still going strong.
My set-up is a PC, a TV, and a console in a relatively small room. To be honest, I'm thinking of leaving receivers behind and using an HDMI switch and soundbar/subwoofer, but I need to weigh pros, cons, and price.
Any advice would be appreciated.

Best I can describe it is it intermittently does some very quick (for like 1 - 2 seconds) up and down flickers, which on first glance can look like a slight blur. However, after repeated occurrences you can tell the image is moving very slightly up and down very, very rapidly.
Anyway trying to determine if this might be worth fixing vs. buying a new TV. If so, any recommendations for a good TV repair technician?

iis this on all vedeo sauces?

You can attempt to open it (follow a YouTube disassembly guide how to do this), spray clean with WD-40 Contact Cleaner and re-seat all the cables and connectors.
If that does not solve it, my 2nd guess is a component on the timing control (T-Con) board is going, and could be something as simple as a capacitor, but it'll be easier for you to just replace the board. It could also be any other board who knows without testing? https://www.tvpartstoday.com/6871L-4430C-LG-T-Con-Board-4430C-6870C-0645A-V1-p/6871l-4430c.htm

So knowing the cost of each component that can go bad, I would suggest that you carry it to a TV repair store, let them diagnose for a fee, and you import the replacement board for yourself and replace it. It's up to you but I would do that, rather than throw it away and buy a new one. It's only about 6 years old?
TV main boards are very easy to change. Just be careful with the ribbon cable if you have to remove and reseat it.dredman1 wrote:maj. tom wrote:Either loose or damaged ribbon cable/connector. Maybe.

Thanks. Yep its about 6 or 7 years old. But its basically on EVERY day from 6am till about 9pm in a room that has no a/c. I have a small fan blowing at the back of it, but thats about it for cooling.
Will check out some vids to see how involved opening up and identifying/getting to the connectors are and see what I can do.
Question tho: how difficult are those PCBs to replace? I know a capacitor will involve soldering, but if changing out the whole board does that typically require unsoldering and re-soldering in, or are they usually just pull out and snap in?

Once the Amp and the aux Input section working, could use the rest just for display/aesthetic.
