Question about Zenith C34W23 34" TV
Have a Zenith model Z20A21D and am unble to program my cable channels. I follow the weird on screen menu (which also sometimes does not want to go away), but still nothing. I put an alternate tv there to see if my cable anntena is ok and it is. FYI: I do not get pictures or sound, just the menus and the inability to program. Help!! Thanks!!

Redbarron, Might be that it could be some other circuit loading down the power supply and the x-ray protect has it in shutdown mode.. First I'd check the following: Cx2110/100uf@35v C2104/10uf@50v C2109/10uf@50v C2101/4.7uf@50v(Located Off Pin #4 Of Icx2100) Cx2107/2200uf@25v C2108/47uf@25v Cx3413/22uf@50v Cx3416/100uf@50v These are common lytics that fail in that unit. And Icx2100 Vert Ic is known for failing and shorts to Ground, Zenith p/n #221-00992 or the generic Tda8174. But if you don't do the testing and repair yourself you could pull the board and send it in to Tri-State Module for a complete overhaul. According to their pricing it would cost you $74.95 plus all your shipping.. Tri State's phone number is: 800-203-7484 Hope this helps. Bill

Dark picture? hmm.
meaning there is no brightness variation, assuming this is the fault I think U might be having low screen voltage. Check for high value ( around 2W) resistor, preferably from 100K to 680K on the "C" board or neck board. Post back
