My rca hdtv does not have picture only voice


Some possible causes:

No filament voltage to the three tubes.

No high voltage to the tubes.

The set is also prone to bad connections at and around the high voltage transformer.

How do i find out if sony kp/57ws510 picture tube is bad


While the set is prone to bad tubes a double or 3d like image is convergence--this model uses two of the STK-392-560 CHIPS for this.

Go into customer menu and call up convergence--if off and will not adjust in any area of the screen the chips are bad.

Sound, but no picture


If before it was going rather bright red or a version of that--it is related to the circuit for the red picture tube this set uses---the tube itself or the circuit board that plugs onto the end of that tube.

If bright red, green or blue screen set will detect too much current being drawn and blank or turn tubes off; not likely a do it yourself repair and this set is prone to this and many other problems---Just Google the model number with "problems" and see what I mean.

I have a husqvarna chainsaw 41(1994-05) is what the model number is showing the carb has been rebiult new gasgets it has fire but will not run can u help


The 41 was quite prone to blowing the crank seal on the flywheel side, remove the flywheel and check, at the same time check the flywheel key has not sheared, behind the carb fixing plate is a rubber induction tube, make sure this has not split, als check the impulse seal underneath the induction tube.

My picture is blurry and discolored.


THAT KIND OF TECHNOLOGY IS PRONE TO WHAT ARE CALLED CONVERGENCE FAILURES. PROBABLY THE MOST COMMON FAILURE HAS TO DO WITH THE CIRCUIT THAT KEEPS THE 3 PICTURES FROM EACH OF THE PICTURE TUBES ALIGNED TOGETHER.

TO IDENTIFY PART ON '93 FORD 302 EFI V-8 USING EXPLODED VIEW DIAG


Sounds like it is the tube to part of your emissions equipment. It usually goes to another hose that goes to a one way valve from the air pump for the air injection for your exhaust gas recirculation system. These are prone rust and can be purchased from Ford for replacement.
