Have 1080dlp sound but no picture


DLP type sets regardless of brand all have some things in common--use a lamp, a Ballast, etc.

If sound you need to see if the lamp is coming on when set is turned on--usually in these type sets if no brightness one or more lights on the front of the set will be blinking---no model number is indicated with this question..

We heard a "pop" noise


The pop noise could be a capacitor poping its top up.This is a common problem to most TV sets today. Usually located at the power supply board.Once this parts give up it usually shorts the circuit and blows a fuse.Replacements of these parts mentioned will often remedy the problem.Flashing power indicators indicate a problem.If you have the chance of counting how many the blinks are I could have told you the problems code are and the source of the problem.

RCA HD50LPW164 turned on TV made a pop


the loud pop you heard was probably a capacitor blowing its top. The grinding noise is likely high voltage arching that was occuring due to rising voltage since capacitor isn't there to smooth it out.

Loud pop Blank screen 42 inch Viore Plasma


Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

Read replace lamp then afew weeks later heard pop noise and now black screen


Two things in your TV can make that popping sound. One is the bulb of course and the other is a capacitor. Have you pulled out the bulb to inspect it? My guess is that you have broken glass in the cooling fan, which is why there is a grinding sound. Most bulbs tend to contain the glass from getting everywhere as it's only the filament inside that pops creating little diamond looking pieces inside the lens. If a surge was strong enough or if the bulb was poorly manufactured, the whole unit can explode inside spraying glass everywhere.

If the bulb looks fine, the pop must've been a capacitor on one of your circuit boards resulting in no display. Since the TV still powers on, your power supply and it's fuse appear to be fine. Check the bulb first and go from there.

No picture, just a high pitch sound


Sounds like the flyback and horz output is shorted.
