You possibly have a cracked solder joint in the vertical circuit, possible the vertical Ic itself. You'll have to remove the board and look carefully at the soldered connection of the vertical circuit and see if any are ring cracked. Some soldering should fix the problem. If you let the problem go too long the heat these cracks generate will eventaully short the vertical Ic..

My emerson 20 inch flat screen tv is encased in a dog house for outdoor use. I can't get to the back to see the model number and I want to buy a remote control for it. Is there a universal emerson...


You should be okay just buying any generic universal remote. Any remote requires programming to work with a specific TV, but universal remotes are easily programmable. The instructions included with the universal remote will detail how you program that remote to work with your TV (usually along the lines of simply putting it in programming mode, and pressing the power button until it turns your TV off, and then locking it in)

How do i change the input on my emerson ewf2006 tv without the remote? i dont have cable or sattelite or an antenna, so i wanna use my ps2 game system to watch movies for now til i get cable. cant do that...


There is one way to try. I would have your playstation connected to the A/V of your TV. Power up your game. Now try tuning your TV to channel 3 of course. Now, press channel down on TV a few times...You may get an input. I'm not sure if this will help, but try anyway. If this fails, you need to purchase a universal remote with an input selection. I recommend a Philips remote. TV remote model # SRP 1003/27. This number is located just left of the universal price code. I found this remote as one of the best. Thanks for asking and show a few hands of support!

you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again

Panasonic CT-27L8SG displays gray screen and white hoizontal line


Is it still under warranty?
If not I would find a good TV Service Shop and have them check out the power supply as there more than likely a 'Capacitor' much like a battery that is going bad.
