Popping noise I have a Hitachi which is about 7 yrs old and its starting to make a popping noise and the screen goes black and white for a second. The noise happens every 30 minutes. Will the condition get worst if not immediately fixed? Thanks

since it is electric, there should not be any popping noise or sounds. Since everyone has their own idea of what a sound is, I would look into this as it could be an electrical issue of some shorting or arcing.

I was watching my tv model LT-50a330 JVC and it made two popping noises and the screen went balck but the green power light stayed on. I unplugged it and could smell something bad like a short. I havnt tried to turn it back on, does this mean I need a new tv, it's not even two yrs old.

it is a common problem usually when the unit is an old enough, the cause is a leak capacitor at horizontal section. sometimes bulged to its casing due to overheat and used for a long period of time.

CRT,s are arcing . This set is over 3 yrs old

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php That crackling sound could be of the color wheel:The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9601073A you can find original here:http://www.discount-merchant.com/Samsung-BP96-01073A-lamp-p/samsung-bp96-01073a-lamp-oem.htm?Click=48173 .Have a blessed one!

I would guess you have a High Voltage Leak at the Anode Lead Cap where it Mounts to the CRT. This is not a area to mess with You are better off calling a professional to fix it. It may be a little difficult to confirm if it is a intermittent problem.

Sounds like flyback shorting out and shutting down high voltage, causes TV to turn off for protection.

I would send in for repair cause this is big $$$ cost!

Turn down the volume and see if you still hear it,a loud pop or snap could be high voltage call your servicer in your area ASAP
while its under warranty and have him check the high voltage circuits for a intermittenting pop or snap.And have the model # ready!! Good Luck!

Check C702 near flyback xformer--if shorted, relace w/3KV cap.Example==102K/2KV replace with 102K/3KV SONY # 1-161-754-00.

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock.
