Re: tv power problem

It sounds like you have an integrated power supply issue. This type of supply truns on the horizontal oscillator which provides excitation to the Horizontal Output stage which in turn work with the HV section of the TV the extra LV levels are supplied by this interaction. That tsss noise might be the oscillator trying to work or the startup circuit trying to work. I would check the Horizontal and HV sections for failed components.

My tv won t turn on i just purchased it today i plugged it in and it won t turn on

Check the electrical outlet which the tv is plugged into. Make sure nothing is loose at the outlet as well as on the back of the tv where the power cable plugs in. Another thing to try is plug a different device into that same electrical outlet and see if it turns on. If it doesn't turn on, it could be a faulty electrical outlet. If you've tried both the remote & the power button on the tv, a shot in the dark would be to change the batteries in the remote.
You could always try calling their tech support at 1-800-256-2487. A last resort would be to return the tv from where you purchased it.

You should check to see if the sound is really coming from the TV- you may have the sound from the directTV cable box composite audio red and white RCA connectors.

Try connecting from the audio out of the TV to the stereo

Try the menu and see if you can adjust vertical and horizontal hold.

unplug tv for 10 minutes - tehn try again.

change battery in remote, if the remote does not seem to work

good luck

Tv wont turn on

The sound can be called screaming from the power supply,it senses a short and creates a frequency you can hear,the set has a problem and it needs to be repaired,I will check the horizontal out put transistor for a short,sometimes it goes bad without a reason and sometimes the high voltage transformer is also bad and both have to be replaced but first the transistor only if it goes bad again then you replaced the transformer too.Seek assistance from a servicer if you are not too familiar with tv service,it can be dangerous.

No sound

Check first if theres a speaker cutoff in the menu of the set or the back of the set. Next see if theres a headphone jack and plug in a set of phones to see if you get sound. If you do a connection on the jack is bad. if you put youe ear right next to the speaker and hear a little background noise or a little sound then its probably in the volume control curcuit. if you hear nothing at all its the audio output IC or the speaker itself is defective. Good Luck
