Can dust cause Sony Trinitron 34" tv to go black and make popping sounds?

Dust rarely affects this kind of set---this model had high voltage problems---and if popping I would unplug it.

To be honest this set weighs a ton and is expensive to fix, average repair can be well over 200 dollars.

A lot of them now are being retired and replaced with LCD sets etc.

I have an F32650 and it wont turn on and also no sound. I also hear this clicking type sound coming from the rear of the TV.It sounds like it's coming from the right right rrrear of the TV.

Sounds like a probable shorted Horizontal Output Transistor (hot) Hopefully thats all. Sometimes the flyback will fail as well. If your not familiar with electronics I would recommend a tv shop repair. If its just the HOT transistor average repairs are 75-110 depending on your location.

RCA 32 in TV no picture no sound just a beeping noise TV power is on

the tv has one part of the power supply working this is needed to have the microcontroller ready to work. But the tv needs more than that for work im talking 'bout the high voltage power supply who is now damaged. the parts required depends on the diagnosis in the bench but at least two are needed. the cost of this repair of course depends in how many parts are going to be replaced, but i concider this repair kind of average in this technology.

Weird sound coming from the inside

TV needs some kind of service and dust inside to be removed.
Regarding sparks sound, it can be leakage of high voltage of Fly-back Transformer. Qualified tv technician can check and repair it as high voltage risk is involved here.
Thank you.

Our screen went black no picture only sound

Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. If this does not bring the picture back, then you should consider buying a new TV. The costs of a repair ( labor and parts) might exceed the cost of a new TV. Your 10 year old TV has served you well, and has exceeded the average life expectancy of 5 years. May it rest in peace in TV heaven.

No Picture but have sound

OK I got my first TV, first to repair myself that is, and I have no training at all but am kind of a tech dork wannabe. So I checked and I have sound but no signal through the TV tuner, so I hooked up my Zenith VCR to aux 1 and sound with signal appeared, the VCR tuner still works :) so I am leaning toward the TV tuner. It is visibly damaged, and I'm hoping it is as simple as a broken connection. I also noticed a vertical flash and pattern of horizontal lines when it is turned off (white). sooooo I push on.... help!!!!!!!!!!!!! :>}

Spongebob tv SB314 no picture or sound

It's very likely junk and would cost far more to repair with labour than to buy a new one. Sorry to be the bearer of bad news.

No picture / No Sound / No nothing

that sounds like the Hi voltage transformer went bad.. If your a tech simply disconnect the horizontal output transistor and see if thats shorted. If it is then it is for sure the HV transformer. If its not shorted look in the main power supply. Its cost is around 40 bucks or so and the transistor is about 15 to 20 bucks. This entire repair should cost ya around 150 to 175. So if you decide this tv is the one you like then have it fixed. Good Luck
