Question about Sony LF-X1 12.1 in. LCD Television

1 Answer

The audio transmits, but no video. . .

This happened after a power outage, could have been a surge on the home base power supply or through the cable TV box attached, after power was restored.

Check all cable and connection first, try unplugging battery for five minutes, you may need to replace the cables to the display.

    Forget about the battery, I mixed your model with an handheld tv.

    In your case leave the TV unplugged for one hour or more.
    When TVs get stuck after a power surge , that is becauso of the internal protection circuit, that keep the TV off.

    You often fix it by unplugging the power cord for a couple of hours, this will drain power from the set completely, and reset the internal circuits.

    If that does not work , that means that the power surge had blown something inside the computer (typically power supply problems) , and you need a technician to find the faulty part.

I have a 32" LED TV and a year ago I lost visual (picture) while the sound was still working. Repairs costed R1400.00 and the same thing has happened again. Why does this happen and what can I do?


Power issues are the most common cause of solid state electronics failures.
So, not so ironically it sounds like a poor power issue. Normally this isn't a problem in most places, and varies with quality and such; but, power brown outs and/or power outages wreak havoc on solid state systems. Audio is less complicated of an encoding and timing, so it appears that everything is working in the set, up to the decoders, this means, it's getting the signal, and it's processing the signal and sending the information to the right parts of the machine; but, when it comes to turning that information into a picture, or audio, the picture part is not getting decoded.
To do this requires great sensitivity in timing as a part of translation. Audio is not as critical as it's basically a single signal, whereas the video is made of colors, intensity, and knowing where the edges are in the code which requires timing as there's little time to buffer the image.

Or it's something as simple as the power supply to drive the lighting, and just shoddy quality that can be protected with a surge protector.

And so, basically, all this is probably handled on a single board or a power supply separate from the audio that drives the LCD lighting, and that could include the programming to decipher the signal and the clocks for the timing which would be high frequency, and it's possible the clocks that get damaged during brownouts and storms, or the power supply getting wonky from the power source and killing the electronics that drive the video.

Since you didn't name a brand; I'd suggest you not use that brand and see if you still have issues, and make sure it's surge protected.

At some point, usually 50% of the cost of a new device, it's not worth repairing; and if it's the second time, I'd include that as part of the math in figuring out if I wanted to do it again. If you don't get that many brown outs, or power outages, then it's just shoddy material; but, I keep all my sensitive electronic equipment connected to surge protectors, and some really sensitive stuff connect with battery backups with surge protection.

If you do have a surge protector, and it has a warranty, and you have your receipt, you may be covered by them for repairs; but, you'd need the warranty. Some are limited, some are for lifetime. But, either way, Power issues are the most common cause of solid state electronics failures.

HOW TO PROTECT YOUR ELECTRONIC GOODS AGAINST POWER SURGES


I have only been giving advice on FIXYA for a very short while but have noticed that an awful lot of the people who relate their product issues , particularly complain about faults developing after power cuts / outages. It is apparent, from a description of the complaints, that damage is being caused by outages that may be a result of power surges blowing electricity sub stations.
There are a lot of damaged audio devices / tvs being affected. As such I advise you TO BUY SURGE PROTECTORS for all you valuable devices.
I have them around the house and although we only get an occasional power cut here in the UK I know that at times they have saved my equipment fron power spikes. The small cost is justified in the long run.

If you have any electronics experience you should check the diodes or the bridge rectifier in the power circuit. Look for burned components or bulged capacitors.!!!Always unplug the unit and wait a few minutes before attempting any procedure!! I have found that capacitors usually fail due to voltage spikes which can happen when power is reinstated after an outage. Always use surge protectors on electronic devices. They have a component called an MOV that will absorb voltage spikes and save your equipment.

My TV will not register channels


Think that your tuner section has been compromised by the surge. Happens. If your other audio/video inputs work you can plug an external tuner in there.

Yamaha RX V671 will not turn on anymore after a power outage


The protection mode has activated.
Reset the protection mode as follows and see what happens.

Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.

Hello,

Depending on what caused the power outage, you may need to replace the power supply in the server. When outage happen and the power is restore. a power surge can destroy power supplies, especially if not connected to an UPS unit.

Receiver will transmit t.v. sound but no picture


Maybe the video portion of your receiver was fried by the lightning. The good news is, you don't need it!
I run all my video sources (sattelite, xbox and dvd player) to my TV with hdmi cables, and a single toslink(optical) from the televison to my 5.1 home theatre receiver. it sounds great and I only use a single input of the receiver for all my video.

If your setup does not have toslink themn use coaxial digital. it is also one wire and probably is indistinguishable in sound quality.

for future, run the power for all your electronics through a UPS or fancy surge supressor to protect them from bad power (and lightning)

Speaker crackle


HDMI is a High Definition Multimedia Interface and has the capability to transmit both AUDIO and VIDEO all in one cable. Your setup right now is transmitting 2 audio frequecys (L/R stereo RCA and HDMI) into the Denon inputs. Not necessary! I would recommend eliminating the red/white audio cable from the direct tv box to the Denon.

After doing such, your receiver should be able to process audio/video signals appropriately. REMEMBER to unplug all POWER CORDS before reconnecting any speaker/audio/video cable, as it may cause a small electrical surge and fry a micro component in your system!

Poor picture quality on my samsung HD TV


Hey xf1racer,

Based on the description that you provided, it sounds like you are using a bundled composite video cable to connect your cable box and TV. Composite video cables generally consist of three color-coded cables: one yellow, one red and one white. While the yellow cable is typically used to transmit the video signal to your TV, the red and white cables transmit the right and left audio channels respectively.

Red/green/blue bundled cables however, are often referred to as component video cables - each of the three colored cables is used to transmit a different portion of the same video image from one device to another, and require a second separate cable (typically red/white) to transmit an audio signal.

The primary benefit of using component over composite cabling is that many users may report a cleaner, more brilliant image on their TV as a result. Please keep in mind however that this is not a guarantee that changing from your current set-up to component cables will improve the picture quality on your TV, as picture quality is often based as much on personal preference as it is the actual configuration and settings of the equipment used.

Additionally, many retailers may suggest changing your current configuration to one using HDMI cables instead to improve picture quality even further. Unlike composite and component cables, standard coaxial cables, and S-Video cables which transmit analog signals, HDMI cables are designed to instead transmit uncompressed digital signals. This typically means that more information is available for your TV to process in terms of color hue, color intensity, as well as image resolution. Again, remember that any perceived improvements will be based on both personal preference as well as your home theater configuration.

Should you have any questions or lingering doubts, I would strongly suggest speaking with a Magnolia Home Theater agent at your local Best Buy™ store for more information. Most stores will have similar TV's on display using more than one type of connection, and sales associates are always able to provide additional suggestions if desired.

Hope this helps you out.

Sincerely,
Aaron
Go Ahead. Use Us.

Tv won't come on


Sounds like the typical power surge created by the outage has caused a power supply problem inside your TV. IF that is it, there not much you can do yourself.
