Question about Grundig GF70-600 TV
My Grundig TV has a full picture but the colours are all over the place ( like a rainbow effect ) in circles on the screen - sound and picture is still clear tho.
Any suggestions ??
You have a magnetic interference problem. First, have you put any magnetic objects like speakers near the set recently. They will cause this. Turn the set off at the wall and wait for 15 mins for the PTC device that turns on the degauss coil to cool and operate. It is the loud burst of hum you here when you turn the set on from cold.
The PTC is a postive tempeture coefficient that allows alot of current to flow at first, heating up as it does, and then slowly less current as it heats. This is why you need to turn the set off and let it cool. If the problem remains The PTC may be faulty allowing too much current to flow and upsetting the magnetic flux about the tube. If you dont have the skills you will need a technician to sort it out for you.
