You did not provide a model so I am not sure of the type of set u have. Wheather it be CRT, LCD, DLP or LED. My 1st guess regarding "color float" is possably the convergence board/section of your set. And the warming up issue could be the result of cold solder connections and/or faulty caps on 1 or more circuit boards. Search your model number through the internet for clues.

SOURCE: Sony KP46WT510 picture goes back and fortto horizontal color bars

The pictures show the result of a bad terminal input board. You can verify this by checking the inputs. Connect devices to the board and try different inputs. You will most likely find this problem on the tuner and component input were your DVI and composite video will be ok. If it is the same on all inputs replace the A board

SOURCE: TOSHIBA 57H82 TV Blurry for 15 minutes till warms up

This is a model first sold 2002.

They have a history of the Hyper board failing. Usually noise or lines in the picture and the warmup time gradually gets longer and longer.

This board processes all signal from all inputs inside the set and is no longer available from Toshiba.

The only way to get one is from a national company called PTS Electronics who rebuilds or repairs them--cost for rebuilt board is about 220 plus shipping and part number for this model is:
Part Number23148024


I have a service bulletin with photos of the board on my computer.

It is a financial decision, not a job for the average do it yourself person to attempt.


Let me know if you have questions or need help.

SOURCE: Picture image is unsettled when

LINES or noise from left to right etc. This is a classic problem in a lot of these sets--that this clears up after a while is also typical---the period will gradually get longer and longer for it to become normal.

This set uses a Hyper board for all signal from all inputs---about two dozen tiny surface mounted filter capacitors on that board---they dry out and lose value---flat caps will when hot attempt to regain some of the value they should have.


Board is no longer available from Toshiba, only way to fix is remove one in set and send out for repair to someone like PTS Electronics.

I have seen experts try to replace the tiny caps--usually several are off value or open---cheaper to send board out. Last one I saw cost was about 200 for rebuild, keep in mind same problem will happen again in 5-8 years.


Let me know if you have questions and if this told you something you did not know, rate this solution as very helpful as I do this here for free.

Zenith z56dc1d dlp tv picture works for about 1 minute then starts shaking and tv shuts off


You may want to get it in a rather warm room and or remove rear cover and use a hairdryer to warm everything up inside the Cabinet--with rear cover off look to see if the fans are dirty etc and if they all come on, if a DLP especially look at the lamp itself and the fan that cools it.

3-D picture with color lines


Seems TV has dry/ cold solder joints (loos connections) in convergence out section.
Please check cold/ dry solder joints in convergence out section in TV, specially on pins of convergence out ICs. resolder these solder joints and all would be fine.
