Loud popping noise tv

THis could be one of the CRTs (Color Tubes) is bad or the high voltage is leaking somewhere.
Toshiba projection TVs have history of yoke problems.
My guess is one of the CRTs is arcing inside. This TV has 3 CRTs red, green and blue. Replacing a CRT is not easy or cheap to buy if you can find it. If you like this try calling a TV technician to track down the high voltage arcing. DO NOT TRY TO DO THIS BY YOURSELF.

Best of luck my friend.

Hi,
According to the symptom the FBT Which is called "Fly Back" is popped, and it needs replacement. Details like Part No. and Description is given below:

145334611 FBT ASSY (NX-6000//J1J4)

Replace the FBT and your tv work fine again.

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.
Hope this helps,

if the noise is from inside the tv in the back,the high voltage transformer that feeds the anode for the rgb tubes,28000volts probably is arcing.

The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.

I just had this same problem over the weekend. Is your TV hooked up via HDMI?? Mine was and i've been having problems with the tv image shrinking whenever i turn on the tv, so i would have to change the channel 1 or 2 times for the image to come up normally. On Saturday I went to change the channel and then all of a sudden I hearld this loud pop and when the image came on it was just a sky blue screen, I couldnt see anything, but I could hear the channel. So I disconnected the HDMI and hooked up the tv with component cables I had and now it works fine. I ordered a new HDMI cable just to see if it will work again. If not, i'm calling Olevia.

Could be a possible flyback. yes.. for a 27inch i would not think it would be worth it... 27 inch tvs are realativly cheap.. the lowest price to repair would be about 200 if you got lucky.

Thats the CBA board heres a link where you can get one but its expensive.

It needs a new FLY BACK transformer. That is what you are looking at. The origionals are not made for the set any longer but insist on having a generic on installed by a local TV shop. I just put one into a RCA 31" and it works nice. Don't throw away the TV. Get it fixed. MAKE SURE YOU INSIST THEY USE THE GENERIC ONE! THEY DO WORK!
