HL-R5656W Unit made loud pop and pic went black, ordered bulb but there is a loud crackling with some flashing going on when I re-inserted old bulb, is this the ballast that needs replaced?


Wait until you get the new bulb to determine that. The old bulb is probably arching as it tries to start.90% of the time the new bulb will do the trick.

Loud popping on jvc av56wp74


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.

My DLP TV made a loud popping sound then went off


first. unplug the set for 5 minutes and see if it will reboot. if it does not the you have 2 problems, the chassis is also bad. next open the lamp door cover, it is behind the speaker grill, and behind the lamp door.
take out the lamp and see if it has broken on the inside if it has it needs to be replaced. mits will send you one i believe it is about 100.00 the number is 915P020010. if the lamp looks ok then the color wheel has probably fallen apart.if this is the case the light engine need to be repaired. check out www.tv-techs.com

Popping sound and picture goes out


Sounds like the flyback or the picture tube. Either items can cause this. If the pop comes from the rear right side its the flyback. If the sound comes from the lower front behind the speaker grille its the tube. Let me know what you discover as I have access to any of the parts you would need.

Toshiba 61H70 Popped Loud & Fixed Then Popped Again & Again ;(


my guess is that that high voltage seals on tubes are leaking out high voltage from tubes if not probly sealed with silicon they will leak out high voltage.replace them and seal coorrectly this may fix your problem
