Its proberally the main controll ic, or the remote sensor is malfunctioning. you will need to check the remote sensor by disconnecting it,, and if you still have the problem then you will have to change the main board.

Tv won't change from chanel to chanel


Do a hard reset to this set and check first. To make it hard reset, unplug the set from AC mains wall socket, and re-plug it back after 10 minutes or so.If this do not help you, check and replace its main system memory IC.

I have an TV Phillips L01-1UAC-7638, the issue is, when I turn on the TV, after 15 or 20 seconds the TV turns itself off, but if I change the chanels the TV does not turn off, I mean if the TV is showing...


Hi, you don't mention the full model number, there should be a number on the back of the TV something like this 27PT543S37A, the problem you have seems to be fairly common and if this is your model number you could try this, on philips model 27pt543s37a will not power-up without changing channels for 5 minutes, transistor number 7461 is leaky between collector and base - needs to be replaced, and a capacitor rated 47 uf (microfared) at 25 volts, should be upgraded to a 47 uf at 63 volts, with a temperature rating of 105 degrees vs 85 degrees.

Hope this helps, I am assuming that you are able to use a soldering iron etc.

If you have no experience in electronics/soldering or how and where to get parts please consult a TV technician, dangerous voltages can lurk about in a tv even when not plugged in so please be careful and if at all unsure leave it to the people that know!

Ocassionally. digital TV did not load correctly, and must reboot and load firmwware to get the digital signals for the TV. Changing channel is not necessary for firmware to load correctly. But powerline glitches might cause a problem..

BEKO TRW325 TV. Frozen on chanel 1.


I turned the TV off. I held in all of the (4) buttons on the front of the TV and turned the TV back on again....this seemed to free up the remote control access and I was able to work the TV normally. The four buttons were the channel and the volume controls.
