Unless you know Solid State Electronics, there is nothing you can do. At best, You could unplug the TV, remove the back cover, slide out the Circuit board, and check the fuses. They will be at the front of the Circuit board, left hand side. But in all likelihood, it is not just the fuses, the Power Regulator STR would also be short circuited (happens often in SONY TVs) and so it is best that a professional technician have a look.

Since the you were vacuuming behind the set before this happened, I'm going to assume that you unplugged an input. Check the wiring, not just on the back of the set, but, on the back of the peripherals (DVD, Satelite, cable box, etc.) If wires are connected, then, take a component, such as a VCR or cable box and hook it up to the RF connector (AKA the cable connector) and run it on channel 3 or 4. If you have sound, then, you have a configuration problem and need to rewire your set. Hope this helps.

Sounds like horizonal output transistor could be over heating. There could be other problems. But I would start there. You can find the part number on the schematic inside the set. If you change it yourself don't forget to use the included insulater. Part should cost between 15 & 20 dollars. You will need make & model # of set at electronic parts store.
Diagrahm inside set will show you location of transistor.

Sounds like a failed vertical amplifier circuit. This is normally primarily contained in an integrated circuit mounted on a heatsink.
There are other possibilities along the line but the one above is the most likely.
Now all you need is a TV repair shop that is still in buisness.

Screen doesnt work, sound works fine. It worked fine last night but wouldnt turn on this morning, why?


is the screen dark?, if is it, see if the TRC filament is light, if is it afirmative, turn a little clockwise the fly back knob that say SCREEN and watch if there is a horizontal line at midle of the tv screen. if is it, your problem is in the vertical stage.

No picture, sound ok


Rca has been known to have bad solder joints in the deflection circuits. Usually around the flyback and transformers.. check it over real good. Just be careful as you can still get shocked after the powers removed the capacitors and picture tube will hold a charge in them.
