Hi! Thank you for using Just Answer today! My name isXXXXX am happy to help you with this! Please bear with me and be patient as sometimes these issues take a little bit of figuring out before we know what's wrong. If you could give me some more information it will be very helpful: -If you push the MENU button on the tv, does the menu show up? -How old is the unit? - Do you have this problem while watching all different devices hooked to this television? (DVD player, cable, satellite, game counsel, etc.)
Please give me this information and I will be happy to assist you further. Thank you, Tim Nolan
MENU does not show up
6 years old
No other devices are hooked up
There are a couple of different things that could cause this problem, the first is the power supply, and the second the main board. Also either sustain or scan driver board can cause this problem.
To know exactly what board is the cause, you need to have electronic repair experience, and test equipment. If you have this let me know and I will assist you in the troubleshooting of this tv. If this is the case, then please do not rate this answer yet, just reply back with the CONTINUE CONVERSATION button and we can get started.
Otherwise you will need a repairman at this point. You can expect a bill of anywhere between $250-350 on average which is really a lot of money to put into a 42" tv these days given the prices of new sets out there.
I am sorry I don't have a quick fix or easy answer for you on this one, please let me know if you have the skills and tools and I will be happy to assist you. Also please let me know if there is anything else I can do for you.
