It sounds like your TV's display has been routed to a different INPUT than the Cable/TV input jack, like a VCR in put or an RCA input. You need to change the input back to TV from VCR or LINE1 or RCA, so on. How to do this without the original remote, you are going to have to look up the program code for the universal remote and program that remote correctly, once done, change the TV Input until you're back on cable.

Techwood 42inch tv model 42832 hd digital white picture with sound then 30mins later picture comes on with no problems.


You have some capacitors on the circuit boards that need replacing. The top of the metal cans are supposed to be flat. If they are dome shaped they need to be replaced.

Techwood tv 42" model 42832 was working nipped to shops so pressed power button on side came back ten mins later switched it on and came on and changes diff colours as seen in video how can I fix this


you have a power supply partial failure if you know how to safely check your power supply check the voltages, swolen capacitors etc. leaking capicators are usually the problem. if you know nothing about power supplies do not look at the tv without the tv unplugged! better yet; have the supply repaired by a professional. a power supply can kill you!

I have a techwood 42832 hd digital tv and it will only stay on for an hour at a time then goes onto standby (the timer is not on) is there anything i can do to fix this problem?


It might be due to some loose solder terminals at its main power regulator section. I do not advice you to do it by yourself, because, the main power regulator section to all TVs are dangerous for an unskilled person to handle. Contact any experienced service technician.
