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,

Won't start weak spark


Hi Karl
Faulty Magneto coil or points or condenser (capacitor) or HV Wire if it uses carbon instead of wire. (This is for radio suppression)
Carbon resistor inside spark plug? Use another Spark Plug.
Rule of thumb is 25 tho contact Gap - thickness of standard hacksaw blade.
Use cheap Neon light tester close to HV Silicon Insulation & compare brightness to e.g. car HV cable.

Hi, I'm looking for user manual of Omron elepuls HV-F126


Hello -

I do not find a manual for the HV-F176 Omron Elepuls low-frequency massager on either the Omron Healthcare United States web site,
https://omronhealthcare.com/
or on the Omron Healthcare international website,
https://www.omron-healthcare.com/en/products/painmanagement

Therefore, if you reside in the USA, I suggest you contact Omron Healthcare customer service and ask about the availability of the user manual for model HV-F176. There may be a copy of the manual of the discontinued massager in the company Archives. If so, there may be a charge for a copy,

See the Contact Us (USA) information here:
https://omronhealthcare.com/contact-us/
There you will find a toll free (USA) phone number as well as a form to complete to send an email message.

Best wishes.

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.

Are replacement motors available for these fans? Lakewood HV 18 Lakewood HV 21 Lakewood HV 21T


mcdevito75 here, If the fan is not too old I would figure yes, but a replacement motor will cost as a new fan, if not more, then you have to install and the blades are a presss fit to the motor.

The light is out.


Usually, you have to remove the outer case after pulling the power cord and wait for maybe 10 minutes to make sure the HV power supply has discharged itself. The lamp should be plainly visible at this point. Be sure to use the same wattage lamp as the original. Good luck!

How do I remove the HV lines on the D board?


Do not cut them.
Push and twist thicker wire in HV block and pull out. HV block has 3 more wires going to 3 guns in TV.
Never cut this wire.
