Did you fix your problem? If so, how?

I am having the same problem and at times it tells me my lamp is bad, which I know it is not because that is new.

Any ideas?

Good pictures but no sound just static


tvs get their picture and sound on different channels, and in europe, and in the usa the sound is on different channels, try in sound settings to set it to your area's sound defaults, so the tv will search for the sound at the right channels.

I have an onn 42 inck flatscreen tv and since last night have lost all colour on screen,,,tried cable and scart all seem ok,,any ideas


Hi.

If the problem happens using different input and devices, then it is either the terminal circuit (input/output connectors) or the processing unit in main board. The terminals are unlikely the culprit if problem concerns different inputs.

I imagine that the picture is not properly B&W (gray-shades) but some kind of reddish, bluish or greenish picture as the LCD will process picture using RGB (red green blue) channels instead of CYMK (cyan yellow magenta black) like CRT TVs.

Test the TV using an external aerial. You will notice if the channels have the wrong color even from static.

Use different inputs, different cables and different devices. beware of SCART cables, the SCART contacts are very easy to break. A defective cable will loose picture. Better testing using AV cables and component cables. AV cables are red/white for sound and yellow for video. If the two-wired yellow cable does not work, then the TV is faulty.
Other test can be done using component cables. Component cables send the three red-green-blue signals on different cables, hence testing is simple. Test swapping cables and see if TV tone stays the same if color tone changes the problem were the cables. Test also using at least two different devices (e.g. one DVD player and one TV receiver or a playstation).

If you find that the TV is defective call the manufacturer at the number listed on manual. If the problem is that one or more RGB channels do not work the TV main controller board must be replaced.

Sony Trinitron: Frozen Static Issue


you could be experiencing two problems. the first part of your description states the static with two horizontal bars, this problem is usually erratic and it is caused by a defective varactor tuner(this happens while watching a channel thru your channel selector) the second part that it also happens while using the front hookups could be taht the front input connectors have developed some loose solder connections and thus the video problems (very common problem)

3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall)

4- Release the power button

5- Plug in the TV into a different outlet

Suddenly no sound & no picture overnight: is my TV dead?


If you have static siugnal, sure TV is not dead.

Check the aerial cable, ensure it is well plugged in and getting signal.

If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.

Test the TV on standalone , connecting it to an external antenna.
Tune again the channels, and save the preset.
If still no signal then the antenna socket on the TV may be defective.

Try using the TV with a DVD.

If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.

Call the phone number listed on tv user manual to get support, and eventually repair it.

White Noise Sound


Your problem is somewhere between the tuner and video detector circuit. The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess! After the audio passes through all this, it is detected and sent to the audio processor. If any frequency has drifted away from it's value then you loose the sound. SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem. Stargazer

Tv seems ok by static and now, no sound (or very faint)


The problem you're describing sounds like a tuner problem. BUT you say that you have the same problem with A-V input too. That's weird!!! Possibly the electronic TV-AV switching circuit is messed up and stuck in the TV (tuner) position. If this is the case you DO have a tuner problem and a switching problem too.
