If you tried to clean the mirrors or someone else tried, there may be an object on one of the picture tubes. I've seen this happen. In one case I repaired a projection TVwith a piece of black tape across the red tube. It may have left the manufacturing plant this way. Please check and see if a cloth is laying on one of the projection tubes. If not, you have a contaminated picture tube, replace the fluid. Thanks for asking!

is the blurry all around the picture have different color like a smear of red, blue or yellow?
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.

Green line in middle of tv when switched on


Is there a picture with the green line going through the centre. If it`s just a green line with no picture, it sounds like the Frame (Vertical scan) Output IC has failed and possibly the safety feed resistor near the LOPTX. The reason why it`s a green line is to protect the tube from phosphor damage. The older TV`s would produce a VERY bright white line across the screen which could burn the phosphors withing the tube if left turned on in that condition. It`s not an expensive repair, but is it worth it with the price of Modern TV`s nowadays. If there is a picture with a green line, it may be due to phosphor damage, in which case, it`s a new CRT (tube). Ian

Intermittent 3 inch green vertical line-5 inches from right side


it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected
and if all seems to be ok, the DG board will need to be replaced.

If you dont have any repair skills I would recommend you to take you TV to a repair shop since this is complex repair

Panasonic - Poor Picture Quality


There can possibly one problem. If you check on tube bords. There is a white plug that plugs into the tube. If you carefuly open that white plug, there is 2 silver contact point, called the spark. clean it with benine., but it must be clean. If you have to use small peace of sand paper ok. But afther that use clear Q-Tex (for Nails) and cover points. Let it dry and set will be ok.

Thanks

Panasonic Color Rings


It sounds like you have a warped shadow mask in your picture tube if your set uses a picture tube. A shadow mask is like a screen wire that lets the three color guns shoot electrons to their respective phosphor dot on the screen to produce the three primary colors which are mixed properly to produce the scene that is being shown. In other words you have a bad picture tube. Stargazer

Red spot in the middle of the screen


You most likely have a burn in on the surface of one of the picture tubes. What you need to do to confirm this, would be to take off the front screen, and with the set turned on, look directly into each one of the lenses, and see if you see a mark on the green or the blue tube. if this is the case, and I am pretty sure it is, the picture tube will need to be replaced, but this set is not a young thing, as the green faint lines is most likely a bad capacitor in the screen drive circuit. If the picture tube is indeed burned on the surface, most likely be better off buying a new TV set. Good Luck

No picture, only sound


The set has a shorted vertical output IC, probably a TA8427k. The capacitors around the heat sink of this IC dry out and cause the IC to run hot. The correct repair is to replace the vertical output and the electrolytic capacitors near it. Also use 105 centig instead of the original 85 centigrade. The is some time a pico fuse or current limittng resistor which must also be replaced. This a common problem with Toshiba and is not a bad picture tube. The usual cost of this repair is around $120-150 depending on the integrity of the technician. Scrivitron
