There is a only a vague picture on the screen. There is sound but no picture. And the problem is not the setup/tv menu. What is the problem. The TV is only one year old.


As a preliminary step, try unplugging the power cable and then push the power button continuously for 10 seconds (this should drain the flea power from the capacitors inside your monitor). Now plug the power cable back and turn on the TV to check.

This can happen when the back light / the back light circuitry is not working which actually lights the LCD panel in the monitor. Please check for the warranty for this product if so immediately contact RCA tech support. If the monitor is out of warranty then its time you approached a local TV / Monitor repair technician.

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?

My philips lcd tv has sound but no picture what is


change the backlight (cold cathode light) on your monitor.. If you are able to open the back of your lcd monitor carefully, the backlights are located at the upper and the lower part of the edge .. replace it with conventional cold cathode lights(protective tube was removed)... there are also instances that backlight was good but the ballast transformer is burnt. Replace the ballast. Its very cheap to replace that.

When i connect my laptop to the tv i get sound but no pic.


Computers have two seperate systems - one for video and one for sound.

The only computer (or laptop) connection that carries both video and sound is HDMI. If you do not have a HDMI/DVI connector on the back of your computer, then you will have to use the VGA-composite or s-video connectors to display your PC's output on an external monitor like an LCD TV.

On both my HP and Dell laptops the display settings (Start/Control Panel/Personalize/Display Settings) allow two modes - single or dual monitor mode. Single monitor mode allows me to switch between any one of three possible video outputs - VGA-composite, S-Video or laptop screen, or a split-desktop (display spread over two seperate monitors). Dual monitor mode allows the same display on any two of three possible video outputs.

Switching is performed using the fn keys on the keyboard (fn key plus the F2, F8, etc. function key with the display marking). You guys use single monitor mode until you figure out what your are doing. Select VGA-composite or S-Video.

Non-HDMI sound to your TV monitor or sound system must be obtained from your laptop's Headphone or S/PDIF jacks. Headphone is stereo and S/PDIF is 5.1 surround sound. Headphone is electrical, but S/PDIF may be electrical or optical (laser light). You must set the sound jack that you intend to use as the default on the PC control panel (Start/Control Panel/Sound).

None of these connectors is two-way in the context of an LCD monitor - your PC cannot record a TV picture or sound from the external monitor. To accomplish this you must purchase a video converter box that converts cable TV or video+sound inputs to USB format usable by your laptop. Do this and you can turn your laptop into a Tivo recorder/DVD burner using Beyond TV, Sage TV or a variety of other software packages.

The sound/volume turned to mute automatically?


Assuming that you are using one, take the batteries out of the remote, then turn the sound up with the switches on the monitor. Tactile switches somethings get stuck. The mute switch could be one of them. If it is the one on the screen, check the "feel" of the mute button compared to the others. Damaged ones usually feel "flat".

TV has sound but no picture


It is possible one of the internal fuses blew out.
It could be a bad horizontal outut transistor.
It could be a bad secondary of the power supply went bad
And many other things.
If it's just a fuse, it won't cost much, but a lot of them do not look like you would expect a fuse to look like.It might be a little yellow, green, or gray rectangualar box shaped part. :D

You should check to see if the sound is really coming from the TV- you may have the sound from the directTV cable box composite audio red and white RCA connectors.

Try connecting from the audio out of the TV to the stereo

Try the menu and see if you can adjust vertical and horizontal hold.

unplug tv for 10 minutes - tehn try again.

change battery in remote, if the remote does not seem to work

good luck

No picture or sound


On mine the indicator light is indicating that it is in STANDBY mode, which means it is OFF. Press the button again, which will turn off the light and now the tv is ON. Now merely press(possibly multiple times) SOURCE to find the correct source for your Cable/SAT and your good to go.
