Re: 14" t.v. when i increase the Volume

I believe you have a regulation problem ,when you increase the volume the audio output IC draws more current therefore the power supply has to keep up with the increase in current,the symptom might happen if you increase the brighness to the max as well,the voltage changes need to be monitored closely to diagnose what component is not doing the work.If you are familiar with tv service this is a problem that will give you a challenge but if you are not too familiar be safe and let someone else get the headache.Let us know how it goes or if you need more information.

No volume

Look on remote to see if there is one button labeled "mute." If so push that when tv is on and see if that fixes sound. Or find volume buttons on tv and hold down button that is for increasing sound, should show a scale on screen with volume increasing.

Cable stations 2 - 12 fussy, distorted. All higher channels perfect.

This is caused by a bad ground connection. Check all of the connectors to be sure they are not loose. Also check the cables themselves. It is possible that the ground connection inside the set is bad too. If the cables and connections appear to be OK, try moving the set to another location where the picture is good. If hte pitcture is still bad, the TV tuner may have a problem internally.
Keep us posted.

Tv repair

You don't have to buy a new tv, it is a fairly simple problem, your vertical ic is blown, and it could be the powersupply to the vertical ic also. To verify, slightly increase the screen voltage, and a horizontal line will appear on the screen, if the voltages is okay, change the ic, but first try resoldering the ic pins. Good luck

Sound form Bush TV

It could be several problems, I'll share with u a couple. All of them need a tech.[technician]
Your volume control works by adjusting the voltage\current to the speakers. The VOLUME CONTROL could be damaged\fixed at a point [even if you are raising\lowering] at high volume.Sometime the control has a crack ********\********* in such a way that the volume arm won't go past crack[see above] on HIGH volume.
The audio IC could be shorted in high volume. Sometimes the audio IC is PART of a 64 (sixty-four) pin ckt. How do u test for that if u are not a techo'
Let someone take a peek at it.

Picture is unwatchable

I have not seen this happen in a long time. Ok first of all that is a sign of poor High voltage regulation, which is not user serviceable. I suggest you find one of the shops on Fixya that can fix this for you, or you can take it to a shop near you.

Picture break up

My first gut tells me that this is a power supply problem. The power supply runs out of capacity due to the increased load of the audio amp. Possible problems might be power supply capacitors have changed their value (lowered), if it has a linear power supply, the full wave bridge (that converts AC to DC)might have a bad diode, if it is a switching power supply one or more of the output capacitors may actually be open. Another possible problem is a cold solder joint. Does the picture breakup occur when the case is slapped? This could indicate a mechanical failure (like a solder joint). Is this the only symptom that this set has?
