Check soldered-in micro fuses in power supply. Ex.--F851,F852.
If there is a blown fuse, identify which B+ circuit it protects.
Most common - convergence IC's bad===replace.

Toshiba tw40f80 cannot adjust green and blue


ok, if you do have a sound problem it is separate from the convergence trouble; this set uses two STK-392-110 ic's. you need to change both and any of the resistors near them that may be gone or open---then adjust the set with the original remote--you can do the adjustments in the customer menu or if needed in the TECH menu-I can tell you how to get into that menu--if you have no sound from the speakers in the set that is a separate issue.

I do this here for free--if you have questions or need help reply here--if this has helped you give me a vote here.

Most of these sets with a convergence problem just need the two chips replaced and the set adjusted---you can buy both chips on Ebay for less than 14 dollars plus shipping.

Tv clicks on red light comes on then begins to blink no picture


Well it seems more to be an issue with the ballast, that doesn't have enough voltage to keep on with the lamp. And the ballast is trying to ignite, that's why you hear that clicking sound. Ballast are not that expensive, they're running around 60-70 dlls, It's worth to try.

I have sound but no picture?


Have you replaced the lamp before? If not then it's most probable you need to replace it, also listen closely to see if you notice any strange noises like a clicking, humming, whirling or whinning sounds... if you don't hear any of those noises, i recommend you replace the lamp first, but if you have those noises and need free troubleshooting bc it could either be a color wheel or a ballast go to discountdashmerchantdotcom the troubleshoot is free

No picture or sound on my toshiba tv


In this unit it's likely the convergence amps are the cause. Those and possibly the 2.2ohm resistors (especially R7726) in the yoke return path - that's why you found the open fuse.
