My telefunken 74cm crt tv wont pick up channels while searching channels and ended up with snowy picture or blue screen

SOURCE: TV problem

Are you using cable to get the picture? If you are, make sure the TV set is in the cable mode,If it is then you most likely have a bad tuner in your set. Good Luck

SOURCE: Snowy picture, no reception?

Hi, Your question "Do bigger TV's need an aerial booster or something?" - No, normally it should work straight out. Boosters are used for fringe location not bigger TV. Pls a questions and some ideas: 1. "TV worked fine the night before" was it hooked up to Cable or aerial? 2. If cable, it is necessary that you change the settings of the TV from cable to STD or Air or something like that. Normally this can be done via the remote, menu, setting, set-up; 3. If aerial, you would probably need the assistance of a qualified service personnel. Apparently something got loose inside the Philips TV, not a big problem because you can still receive (BBC 1) but not the other channels, possibly a loose wiring, a disconnected connector. 4. If you feel comfortable working on it yourself, unplug the tv and the aerial, open the back and poke around. Trace from the aerial jack, the lead wires used, the connector to the main circuitry. Wiggle the wires a bit for any loose connection. 5. If #4 is not to your liking or if you do not find anything or no significant improvement after closing it up and running it again, guess you're back to #3. Hope this gives you some idea. Lots of luck and kind regards from the Philippines.

Hi,

Without knowing the specific model, I can only venture that somehow the Parental Lock has been engaged. Often to disable/disengage, a password/code of some sort is required with entry through the remote.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Check the connector of the crt maybe got a resistor open or a transistor in short circuit.
