What is an hv cable?

Trying to figure out why spots emerge. manual says check to see there is no emitter sources (car HV cable or Neon lamp) or other possible interference sources.

what does this mean?

Hi,

If I may add to the postings of devocap and coolguy008 (and with their indulgence)...

Often, HV would refer to high voltage cables. These are ordinary wires but with extremely thick insulation. Some later day versions uses highly conductive carbon inserts instead of wire to reduce electrical noise emissions. They are used where the voltages transmitted are considerably higher than normally used. Examples are:
1. Sparkplug wires
2. Power leads to neon light advertisements
3. wire from the flyback transformer to anode cap in picture tubes.

Possible sources of electrical noise (that uses HV cables)
a. 2 stroke engines such as those in some lawn mowers, chainsaws, old models of snowmobiles, outboard engines, dirt bikes;
b. neon signs such as those in cafes, clubs, hotels, public places.

Hope that this be of additional help/idea other than those posted by devocap and coolguy008.

Good luck and kind regards.

Hey there ShelleySmith, they are basically referring to anything that is conducting an electrical current, around or near your TV. in particular, neon lights, microwave ovens, etc.Also watch for things that can generate static charge. If you can't identify any potential interference, you could move your tv to another area or room to see if this is still an issue there Good Luck!

It's a 5 wire cable that transmits HD signals from your HD components to your HD TV... unlike the 3 wire ones you use to connect VCRs and DVD to TVs... they permit a faster signal speed and allow for a higher bandwidth ! HV may mean HI VOLTAGE witch can cause electro magnetic interference with your tv. When an ac current passes through a cord a magnetic field opens and closes along the cord and sometimes unwanted RF can leak in to your devices via this magnetic field.They are not too expensive..

Goodluck,

No picture no sound.


The screen is blank with no raster at all. There are indications that the channel numbers are changing in the display. This indicates that some of the low voltages are present but these may be derived from the standby supply. Assuming there is no deflection and no HV, you either have a low voltage power supply problem, bad startup circuit, or bad horizontal output transistor (HOT) or other bad parts in the horizontal deflection. Check for bad fuses. (If you have HV as indicated by static electricity on the front of the screen and you hear the high pitched whine of the horizontal deflection when it is turned on, then the following does not apply).
  1. Use an ohmmeter to test the HOT for shorts. If it is bad, look for open fusable resistors or other fuses you did not catch.
  2. Assuming it is good, measure the voltage on the collector-emitter of the HOT (this is safe if there is no deflection). You should see the B+ - probably between 100 and 150 V.
  3. If there is no voltage, you have a low voltage power supply problem and/or you have not found all the bad/open parts.
  4. If there is voltage and no deflection (no high pitched whine and no HV), you probably have a startup problem - all TVs need some kind of circuit to kick start the horizontal deflection until the auxiliary power outputs of the flyback are available. Some Zeniths use a simple multivibrator for this - a couple of transistors. Others power the horizontal osc. IC from a special line-derived voltage. The multivibrator type are sometimes designed to fail if someone keeps turning the set on and off (like kids playing) since the power rating is inadequate. Test the transistors if it is that type with an ohmmeter. If one is shorted, you have a problem. The usual way a TV service person would test for startup problems is to inject a signal to the base of the HOT of about 15.75 kHz. If the TV then starts and runs once this signal is removed, the diagnosis is confirmed. This is risky. Take assistance of some technician also..
All the best

If you can put a light source behind the screen and see an image, then your lamp has gone out. LCD's have an image on the screen but need the light source to show the picture because they do no emitt light themselves.

When powered on, hear a click and it shuts off power internally. removed chassis, click seems to be coming from direction of HV transformer, but not sure. Also, the power source (TV power cord to wall...


This "clicking'; sounds like at HV transformer is shorting out. The sound is made when the ***35-50,000 volts*** jumps across the short. If you are not a tech, I suggest you stop trying it before you cause a fire. Take it to a shop or replace it.

If you are a tech, replacing the HV section or parts of it can be iffy. There is so much that can go wrong, it is bettter in most cases to replace the board, or the whole set. If you're still not dettered, the HV flyback almost always takes the HV output section with it when it fails. If it still works, but clicks, then maybe you can replace just the FB... it's 12 - 15 solder connections and couple of additional wires. Careful of the big red one, with the cup!!! the hole that the cup goes in can retain ***15,000 or more volts****, even after it's been powered off and unplugged for weeks!!!

No picture Just Sound


Hi
There are different possibilities in your case¸but what happened to me ...
The LCD Backligh is out , I mean the bulbs or neons of the screen BACKLIGH, you have to check either the lights itself or the driver circuit which supply the HV to operate it, usually its a separate small long PCB beside the TV main board .
You can try this trick , Keep all lights off in the room and bring a table lamp, preferred a white neon one and face it lighted on the top of the screen with the TV on , try watch a very dark but exact picture with the sound you are hearing. This is a way to be sure that it is LCD backlights problem when using an external light to illuminate the screen .
It worked for me ,Good luck

Hello,

 

Picture quality problems (such as lines, fuzzy image, or wrong colors)

  1. Check the cables and connections: Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
  2. Check the  display issue with  a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  3. Make sure that the image quality issue is not coming from your source signal. For example: if the image quality issues occur while viewing TV , switch the source to a DVD player to see if the image quality problems go away. If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and . If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
  4. Try to Reset the TV ( LCD) quality options. Please look in to User Guide to make the TV to factory Defaults..
  5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV . If the image quality problems still exists across all types of signal sources, the TV should be serviced.

I hope that this should resolve the issue. However, if the issue still persists then please contact LCD manufacturer for further more on the issue.

 

Bye.
