Hi,
In my opinion, pop sound was lamp that got broke.
remove lamp cover and take out lamp from its housing, inspect it, replace it if it got broken.
Let me know model number of your Sony tv if you have additional question.
Thanks.

    =========================================================


    There are two thumb screws at lower corners if you see tv from rear, remove these screws and pull lower front panel of tv.
    In center of lower panel space, you will see lamp cover, remove it and unscrew lamp and pull it out.
    Lamp replacement procedure is also written in user manual, check page-18 for details.

    Thanks.

I was watching tv and i heard a loud pop.then my picture went out but i had sound.red light in the front comes on model number is 50pl9126d/37


Hi,
If it is a lamp led light in the front panel, this is an indication that the lamp is not working. Pop sound was came from the electrolytic capacitor most probably in the ballast board that's why the lamp is dead. When the ballast board gone to malfunction, no high voltage will feed to the lamp resulting to that kind of symptoms.
Faulty capacitor has a physical indication of fault like bulged/dome at the top. Check the ballast board and inspect the capacitor. If you found it faulty, I would advice you to replaced the entire ballast board if you can't troubleshoot it yourself. Click this LINK for the replacement.

Also, check if your unit is still under warranty/extended warranty period, avail it because the manufacturer will fix it for free. Opening the back cover will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

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.

Your filter capacitors have popped due to diodes shorting, P-channel FETs shorting from gate-to-drain. Pull-up resistors have changed value and as a result your capacitors have peaked (popped)....so now the tv is in protection mode to prevent further damage to your tv. Take it to your local shop for servicing, or take it back if its under warranty......

I have a KDF 42WE655..while watching tv, I heard a popping sound.


If the lamp is blowing that soon, the cooling fan is not working, or is plugged with dust. I have heard some people have a filter that needs changing or cleaning. Check your manual. The cooling fan is on the optical block and not easy to get to.
Probably a job for a tech.

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.

If it has "Popped" then I would expect a rather catastrophic failure, and Lamps don't go "Pop.. they just fail more likely a Capacitor, Resistor, maybe even a semiconductor... so it's off to a reputable repairman get a "quote" and proceed from there.

Tv went dead


This sounds like the small blue capacitor next to the horizontal output transistor shorted and cracked, which blew the B+ fuse. The B+ fuse is the solder-in type which looks like a small resistor and the value of the blue cap is usually 1000pF at 2KV.
