My samsung tv model hl-t6187s has no red

The red LED chip has burned out. Samsung purposely overdrives the red LED to make the colors look better and the red one usually fails from heat.

My telefunken tv model:ttv 293a.system has completely lost its color due to magnetic interference

It needs degaussed. Turn the tv off and unplug it for 24 hours then turn the TV back on. If it's still there buy a very cheap degaussing wand on ebay. They come in handy.

Tip: Keep magnets, vacuums, etc away from the tv.

if it is i think the posistor of your tv is not working. it is the one who activate the degaussing coil around the picture tube the prevent color miss-landing upon opening your tv set.

Loss of color after lightning storm

In tradition televisions, each color has its own gun, convergence and control circuit. One or more of these are most likely bad. Repairs on standard CRT TVs nowadays are usually cost prohibitive.

If you turn the color all the way off the picture should have good black and white if not the crt is at fault. If it is good it could be the jungle ic or the possibly the red color driver in the crt board

Bad color

If it is a glass crt then you need to have the set demagnatized with a demagnatizing coil. All tv shops have one. This is worth fixing and usually at the price of a service call.
