    Hello. What happens is when I turn on the tv, the volume is a high pitched screech. I have to mute the tv volume. It goes away after 3-4 mins, but I fear this is going to get worse. It started out a week ago and only screeched for 1/2 a minute. Also, when I change channels the picture become green with vertical lines. That is now fading in and out when I am watching a show, not just turning the channel.

    Thank you so very much,

    Jerry

SOURCE: High pitch screech w/no signal

is this a picture tube type of tv? big in back? If so, it could be the tube/circuit short.

If it flatpanel, it could be a bad capacitor in the DM or "Y" board or even possibly faulty power supply. Further testing will be necessary

SOURCE: screeching sound and display of color bars with no picture

it is two 1000uf 10 volt capacitors on the power board. the tops of the
capacitors will look like they are bulging. total cost of parts around
five dollars. if you can use a soldering iron and have a half hour to
spare this will fix it .there are alot of polaroid customers that have had
this problem and fixed it themselves. just click on the follwing to see
the video on this fix http://www.youtube.com/watch?v=unuS3CvmWtw

SOURCE: Polaroid 3700 lcd (2006): Every time it is turned

Hello: This is a problem with the power supply unit, There are two capacitors that need to be replaced in this unit. They are the two 1000uf 10V Capacitors that is failing on the power supply, If you take off the back there is a metal module in the center of the unit, lf you open it the power supply is located towards the upper part of the system. Look at the capacitors for puffy and swollen tops, just in case you don't know what capacitors look like they look like tall batteries mounted vertically on the board with metal type tops. If you run your hand across the top of them they should all be flat. Look for the two swollen ones and replace. The Value on the Capaictors should say around 1000uf at 10V. Replace with 1000uf at 16V. The reason you television is malfunctioning is that these caps are leaky.

Testimonial: "Your solution was exactly right . The only thing that was confusing was the part about the capacitors being mounted vertically . It is fixed. Thank U "

Turns on then gives a High pitched Screech then shuts down even after totally unplugging it and reconnecting it blinks on then Screeches then turns off rinse repeat


are you talking about just the monitor of the computer as a whole? if you are talking about the computer then, there is something loose inside the case, which is causing the high pitched sound.

Power light comes on, followed by a high pitched whine


Hi, If after trying the TV again later and problem persist, repairs are in order. A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube. Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry. Good luck and kind regards.

High Pitched Sound


I am to believe that your static sensor on the playing head is touching the the head and it sould not. just bend it up "slightly" and the noise should disappear
