How do I stop the hiccups at home

Hiccups are not difficult to be treated and some tips that are used mainly in our daily - life can help stop hiccups effectively.

When I have my hiccups, besides drinking lots of water until the hiccups are gone, I breathe into a paper bag. The method can increase the level of carbon dioxide in our body, and thereby creating more room for oxygen in in order to stop the hiccups.

This article in the link below can help you with more useful treatments for stopping hiccups. Home Remedies for Hiccups in Adults

My sharp tv model 21fl96, keeps turning itself of all the time and its getting worse

Sounds like your picture tube is going and it might be time to get a new one. A problem such as this is costly in a shop and it might be cheaper getting a new one.

TV will not come on

I am assuming this set employs a switch mode power supply as virtually all TV's do these days, the fact that the power LED is on means that the primary fuse is intact, usually means that the primary side of the supply is also working, firstly check the electrolytic capacitors in the supply especially the startup cap which is normally of low capacitance but high in voltage rating, eg: 2.2uf 450V, if this cap leaks it can cause the supply not to fully start. If the problem is still there you need to check that the supply is working, do this by disconnecting the main rail on the secondary side, this will be the highest voltage output usually anywhere from 80-135V and hang a globe of the same wattage as that stamped on the back panel of the TV, the globe needs to be a standard incadescent type that you use in your home lighting, switch the set on and if the supply hiccups then check for leakages in any of the diodes on the secondary side, best to disconnect one leg of the diode. if the globe lights the supply is running, the indication is then that the protection circuit has activated, although I do not advise disconnecting the protection circuit, I have done this to trace a fault, then reconnecting it, normally any faults on you main rail will enable the protection. if this doesn't help, I advise telling me more about the set.
I hope this helps.

Compaq Presario SR1030NX fails to start

Sounds like the power supply or motherboard is biting the dust. U may consider power off, open case and clean out the dirt, check U'r connections and if the power supply smells, replace it.
Else replace the pc. When the power supply dies, it usually stresses the motherboard out and it dies later, sooner.

JVCAV-N2043TV,Horiontal Output Transistor burns out everytime if fix a new one

Hi There,

The Hor Output transistor is connected to the Line Output Transformer. This transfromer provides a lot of voltages around your TV set but includes the very high voltage to the Picture tube...

These transformers are specially tuned to resonate at a certain frequency,
The Hor output transistor needs to match this if the wiring inside the transformer is shorted by "just a bit" the picture will be visible but the transistor is struggling to match the transformer impedance,from the mismatched the transistor draws more current from the power supply.. runs hot then burns out...

Usually manufacturers provide a Trip circuit that detects that an overload on the power supply is occuring and cuts the power to the Line output stage ...this is usually detected by a clicking sound within the power supply its called hiccuping.

If some one has altered the correct setting on the power trip circuit then the next thing that happens is the Transistor goes Blooooey like in your case.....

So to save you a lot of money replacing the output transistor
please replace the output transfromer as well next time...

But please... please... re-check the power supply trip circuit to save you a lot more expense in the future....

Best Regards From YUBEUT
