The TV was free from craiglist but has a problem: The color was distorted due to blobs of red in the top-right corner and green on the right-vertical side of the tube. I have tried to move the adjustments around the CRT neck but this only moved the blobs around. I hope somebody can offer some help. I am handy with solder gun and am not afraid of trying. It gives me satisfaction to fix things and not throwing away TV that appeared to have minor problems only.
Thank you for any help.
Hello!
The manual to this TV says:
Trouble - Poor color or no color
- The station may have broadcast difficulties. Try another channel.
• Adjust the TINT and/or COLOR in the PICTURE menu.
• If you change the direction of the TV while it is turned on, the picturecould suffer from color shading. If so, turn off the TV and allow it to cool
for several hours before turning it on again.
Here is a link to the "Troubleshooting" part of the manual. I hope it will help you

Toshibas are notorious for developing shorts in the inernal guns of the picture tube. In your case the green gun is shorted to G1. The noise you heard was an internal arc between the elements. It is unfortunate however, the repair of this problem usually requires the picture tube to be replaced. Sometimes a savvy technician with sencore picture tube rejuvenator can remove the short. This however usually does not last. Scrivitron

this is degaussing problem keep tv off for half an hour and if you have changed the direction keep it as it was. if any magnetic thing is there near to tv remove it like speaker or headphone etc. hope this will help.

If degaussing doesn't work, it may just be time to pony up and replace the crt as it sounds as if the shadow mask inside the tube has come loose. And, as you know, there is no opening that to service it.....accordianman

your tv has become magnetized the easiest way is to find a deguasing coil to demagnetize it however only services shop usally have those! you can try unplugging and turning set back on several times to see if that will clear it up as sets have a built in deguasing setup good luck from television tech!
