Hi everyone.

I’m new to CRTs and don’t have much electronics knowledge, so I’m hoping someone can point me in the right direction.

This is a Sharp C14R12.

Here’s what happened:

-The TV was working perfectly.
-I made the mistake of leaving a speaker on top of it for a few days.
-The image became distorted, but after removing the speaker and leaving the TV unplugged for a while, it came back to normal.
-Later, the problem returned on its own.
-Now the TV takes a long time to power on. It seems to “wake up” very slowly.
-When it finally starts, the picture is heavily distorted (photo attached).
-I also noticed a burning smell.
-Today I tried powering it on again after it had been unplugged for several hours. While it was starting up I saw a small orange spark somewhere inside the TV, so I immediately unplugged it.
-My HDMI splitter and HDMI-to-AV converter work perfectly with my other CRT TVs, so I don’t think they’re the cause.

Someone suggested it could be a B+ power supply issue, but honestly I don’t really understand what that means.

At this point, do you think this TV is still repairable?

What would you do next? Should I remove the back cover (without touching anything) just to inspect for obvious burned components, or is there something else I should check first?

I really like this TV and would love to save it if possible.

Thanks!

Tenho 3 crts aqui e tentei fazer um esquema de vídeo Wall. Liguei esses dispositivos da imagem nas 3 de uma vez e percebi que ao ligar todas fizeram um bagulho estranho e não ligaram normalmente. Rapidamente desliguei tudo e as outras duas parecem normais, mas essa pequena ficou com a imagem toda distorcida assim. Estou sentido um pequeno cheiro de queimado saindo dela. Eu estraguei tudo ? ;(

Edit - tirei o maldito auto falante de cima, tirei da tomada e vou esperar para ligar amanhã novamente e ver o que acontece. Realmente torcendo para não ser algo muito sério :,(

Picked up this CRT from the cafeteria at my brother's company. It had been sitting there unused for years, so I couldn't let it go to waste.

My brother helped me load it into the car and then asked:

"So... how are you planning to unload it by yourself when you get home?"

That's when I delivered the line that became this post's title.

Now I'm home, the CRT is still in the car, and I'm starting to think he may have had a point.
