Sounds like the power supply is making that noise. At this point I would just exchnage the TV.

Have to turn way up in order to hear


Have you gone into the TV's menu to make sure that the audio outoput is not set to "variable"?

On my Sony I have the option to set the audio output as "fixed or "variable"

make sure its set to fixed

if that's not it try a different input on your receiver. you can use anything EXCEPT PHONO.

Lastly on my Denon receiver I have to specify how each input should get its signal if you are using an optical cable then you may have to go into the menu and tell it to look for a digital signal not an analog one.

Hope that helps

When I turn the tv on It makes an awful high pitched sqeeling sound for about 5 secs then silence then back again. Its a pattern. No Picture and lamp isn't coming on. Im thinking the lamp is trying to come...


Have the color wheel replaced on this unit, The high squeal is the color wheel bearings gone bad. Fortunely on this unit it can be replaced with out purchasing a entire optics engine assembly. The unit will not ignite the lamp until the color wheel has gotten to a pre-determined speed. Around 9600rmp, if it does'nt then the ballast will not get the signal all is well and ignite the lamp.

It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.

Tv will not come on at all


I had the same problem with my Sylvania TV. Turned out that the power supply in the tv was bad and had to be replaced. TV worked great for about 2 years then the same thing happened again. I recommend buying another brand.
