Our CAL232 TV will not turn on. When pressing the power button, you can see a red light and a green light, but the screen doesn't start up as normal. The TV then tries again after about 20 seconds, but...


Hello,

My LOEWE CAL 232 will not power up. When the power button is pressed, the monitor turns on, with the LOEWE on the monitor, then the TV continues with the previous activity (antenna, DVD, VCR etc.). Now all that happens is

1. the red light comes on

2.after about 1 second the green light turns on for about 12 seconds

3. the the green light turns off for about 1 second

4. then the green light turns on again for about 12 seconds

and this continues until the power button is pressed to turn the TV off. During this time, the monitor does not turn on and the only sound I hear seems to eminate from the power button.

Any thoughts?

How to tune universal remote rm-300f+ to my tv


How to do an auto search for a Livewire Rm-300f+ Universal Tv Remote. These cheap (£1.00) remotes are available from poundland, etc.

1) Turn on your TV, ensure it it tuned to a channel and the sound is on.
2) Press the [set] button for about 5 seconds, until the LED stays on.
3) Press the MUTE button, the LED should flash twice.
4) Point towards the TV and press the power button. Don't worry if nothing happens.
5) Press and release the power button every second or so, eventually (for me about 120 times) the sound will go off. NOW press the [set] button to confirm your setting.
6) Pressing the power button again should switch the TV off. If not you're going to need to go through it all again.

Hissing sound from a Panasonic old TV...Sound and picture are OK. The hissing sound even continues when the MUTE on the Box is ON. The hissing only stops when the MUTE on the TV is ON. I am using the...


If you disconnect or power off the converter box does the hiss go away?
If you connect a VCR or DVD player does it still have the hiss? We
need to isolate what source is causing the hiss if it is from the set or
if it is from the converter box.
When you turn the volume control down on the set, does the hiss
reduce in level? If mute stops it, it should reduce in level as you
turn the volume down. Then turn up the sound level control on
the converter box whether its a manual control or by remote. If you
can get a combination that minimizes the hiss and gets higher sound
level from the programming that may cure it.
I am not familiar with the converter box you are using. Are you using
Audio/Video cables from it to the set or is it coming out with coaxial cable
and used on a channel? If you are using a very old set with a tuner input
perhaps the fine tuning is out of adjustment.

TV screen wont turn on but just a loud noise coming from the tv


I think maybe the G-board needs to be replaced. A TV shop will have to repair it. They normally start around $200.00

Hissing Sound


A hissing sound that comes from the back of the set (not from the speaker) usually indicates a high voltage leak, most likely around the "suction cup" at the top of the picture tube or around the flyback transformer. Remove the back of the set and turn it on, and when you hear the hissing sound, shut off all the lights in the room and you should be able to see a purple-ish or white-ish glow from the spot that is hissing. Shut the set off, discharge the high voltage and clean and seal the problem area. Of course this should be done by someone experienced with stopping high voltage leaks.

Sony KV-20FS120


It's normal for new sets, especially Sonys to do that due to some sort of gas build-up in the new tube. My set still gets a high-pitched buzz after power on and lasts for a minute or two before silencing. If the hissing continues when the TV is turned off return it to the shop ASAP. It could be a problem with the power supply, something getting ready to blow up. Good luck
