Question about Sony KV-27V42 27" TV

Noise when turned on

My sony which i've had 7-8 years has been making a noise for the last year or so when turned on...I would describe it as like a loud electrical thud or buzz for about a second ... picture comes on and is fine...have noticed on the wall behind the tv where back of tube is close, a black burn-like spray...nothing smells like burned wires,etc while in operation....what might be the problem?...thanks for any insight

For the age of the set I would guess you have many loose conections in power supply and horizontal driver circuit,you need to call someone who can locate all of the overheated areas and resoldered them.Do not try to use it anymore or it will fail completely.Do not do it yourself unless you know how to safely work on a tv set.

Loud noise when power steering is on full lock Kia Sedona 2004

There may be 2 possible causes for this problem. THe first may be cv koints failing or excessive turn angle of the wheel which would be binding up the cv joint. This can be checked by a wheel aligner testing the maximum turn allowed at the wheels.. The second is that power steering pumps should never be operated at tight full turn. To umnderstand this consider this. Power steering pumps are only under load when you move the steering wheel ans if you turn a bit the pump moves the wheels and then the pressure is let off until you move the wheel again. You have to move the wheel to shut off a valve in the box that allows the pump to build up pressure. When you hold the wheel hard against the stops at full turn you are making the pump work at maximum pressure and if you continue to do this you can expect premature pump failure. Jusat turn until you hit the stops then ease off a fraction. The noise I expect is the pressure relief valve in the pump is releasing rapidly and it probably sounds like a hammer hitting something metalic. Try the alignment and try not holding the turn hard at hard full turn. Haveing the pump pressure checked might also point to a fault

I have a 25,000BTU Enerco IR garage heater that is about 12 years old pilot light does not stay completely lite it makes noise and smells like gas

When was the last time you cleaned and serviced the heater? From what you described, it sounds like the pilot is clogged, as well as the burner. That's why it's making noise and smells like gas. Not all the gas is being consumed.

Loud noise during spin cycle

My formula: Purchase price divided by # years before service = Cost per year. If the cost of the repair divided by the expected # years it should last is equal to or less that the first then I go for it(usually figure the replacement parts to last at least half as long as the original)
