NO , nobody can do that, ever, only testing reveals what is wrong. a shop does that with tools and documents you do not have and skills. the TV is 11 years old (2009) the bank lamps can be dead. for sure most the boards inside can fail, both power ,digital and the back lamps' why not let a shop do this or upgrade cheaper. like all others do..

bottom right hand side of screen. directly behind the screen or on the very bottom. the touch sensitive control pads are deceptive. there is no actual "button" per say. try using a flashlight to locate the power symbol along with the menu and volume "button"

pretty simple really don't install intake put push rods to hydrolic lifter dish and other end to rocker arm hold in place and tighten nut

bottom right side of screen, either on the very bottom or the back of the screen. should be a touch sensitive power button along with menu and volume controls

i dunno but mine is doing it and i have only uad it for 1 year

Sounds like the screen is no good or the circuit board with the drivers that operate the screen went bad which is a replaceable item

That depends. Most older televisions can't handle more than 99 channels. Also your cable provider will set the amount of channels you can receive.

I'm pretty sure the Sony codes work on my TV.

It think it might be a fault on the T-Con board. Could be a bad soldering joint or bad connection. But could be something faulty on the board itself.

I would certainly have a servicer check the Cable/satellite box. I have seen this with Dynex TV. But try this. Power off box, if there is a service card, take out, unplug box for one minute. Plug box in, insert card and power up. If there is no card, do as said...only. Let me know what you find out. Matt of Martins TV Repair.

Try opening it manual with paper clip od needle. On front side of dynex, there is a little hole near disc tray. Try puching needle or paper clip in that hole until disc tray open.
