Question about Samsung TXJ2879 28" TV

1 Answer

High pitch sound and fuzzy

My Samsung makes a high pitch sound as soon as I turn it on. The pitch stays the same despite of different volume settings. It annoys the heck out of me. Second problem has to do with the picture quality. The pictures seem out of focus. When I watch baseball, sometime I can barely make out the score. Is there anything I can do to fix these two problems? Thanks.

The high pitched sound, probably not, unless you open this TV set and find out what is making the noise and replace the part. Most likely a coil or transformer is vibrating so fast that the frequency is very high. On the focus, possibly can be adjusted. Now when you take off the back of this TV set, i must warn you, follow my instructions to the letter as there is enough High Voltage in this set to make a grown man cry! After you take out all of the screws off the rear cover,carefully lift up the cover straight up. Oh by the way the TV should be face down. Opps! Not stand back up the TV set and there will be a Grey or black block like looking thing with a large red wire going to the top of the picture tube. on this block you will find two controls, one will say screen, and the other will say focus. DO NOT ADJUST ANYTHING ELSE WHEN YOU ARE IN THIS TV SET!!! No slowly rock the focus control back and forth till you get the sharpest picture. Put back on the back cover and enjoy!!! Good Luck

High pitch noise from speakers

Hello there!
Sometimes High pitching its just that, static on the area, like if you are near a microwave, or near other electronic equipments, but, if the skreetching sound keep going or even if you do nothing it could be a line inside the sound card, or you need to clean the volume botton with special electrical cleaner. other that these, its contacts, or bad cap for the volume board inside.
Good Luck!
