TV Sparks inside case

When I power up this tv it sparks near what looks like the power supply. Bright blue power! Looks cool at night but not as good as the Olympics coverage after 3 times.

I think I would turn it off and unplug it. You could get an estimate on reparing the power supply cord or whatever the problem is or the TV maybe ready for replacement.

Yes,there is a fuse in inside on the tv main pcb board near the power a/c cord.But if the tv have sparks,main pcb board could have more other components fries too.If tv less 10 years repair it by a shop,more than that should buy a another tv.

Sony Trinitron won't power up


if the power went out all that may be bad is the fuse; follow the power cord inside the set and it will take you right to the glass fuse; these sets also had problems where the power supply in them fails--several parts get killed instantly--if this is the case---good advice would be to look for a new tv.

Weird sound coming from the inside


Hi,
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.

No Power


you need to isolate the failure.
first, measure the voltage (called B+ usually) on the biggest elec. capacitor in the power supply. This should be about 130-160 Vdc.
If this isn't here, then the problem is in the power input circuit.
If there, then the high-voltage supply is down. If the set is anywhere near 10 years old, then replace the flyback transformer and its transistor (H.O.T.) and go from there.
The worst case is that a power surge or something has killed the TV's brain chip and you'll have to do a board replacement.
Let me know.

Arcing blue sparks internally


the thing which you have seen is resistance not the capacitor. whenever that goes hot or arcing it is due to heavy short ckt in tv. as you are not much aware of tv technology please caall skilled person to do it for you. please now do not start again unless it is repaired. otherwise it may be problematic. good luck.

Rca tv electrical problem


Hi, If the TV is still operational, what you are hearing are probably high voltage arcing. Most common are in the anode cap area brought about by accumulated dust, grime and dirt on the outer glass envelope of the picture tube. This occurs mostly after a continuous or heavy rain or when the surrounding air is damp. Since the unit is still operational except for the "sparks", this should only require cleaning of the above stated area. However, there are extremely high voltages even when the unit is off that perhaps you are better off seeking the services of a qualified TV technician. Other possible areas of arcing are the fly back transformer, the horizontal output transistor PCB soldering points, the G2, Focus solder points. in some remote cases, it can be just inside the neck of the PIX tube. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

Sparks


Where exactly are the sparks coming from? If you remove the back of the TV, can you see exactly where the sparks are coming from?
