How to find out if your MITSUBISHI REAR PROJECTION CRT HDTV has convergence failure because it no longer turns on.

the set like all has a hard reset which requires a four digit number code and the original Mitsubishi remote---sets almost everything in the set back to original except convergence.


also, don't buy any TV or electronics on CL as people dump their problems on someone else..

hi welcome to fixya
i want to clarify first the problem sir so as of now the problem with your tv won't power on then you are using again the old main board is that right ? when you use the new replacement main board the tv is functioning will the only problem is that the HDMI / DVI inputs doesn't work. and now you encountered power supply problem like won't start up or something that cut the supply in which the stand by indicator is turn off so as my idea it has a problem with the old board. but before you come up with the board making sure all the connectors coming from the power supply is properly connected to the main board as will as flexible and lvds cable for the T-con board is properly inserted.just let me know if is that what you are asking for so i can give you additional solution thanks for consulting the fixya.

Sounds like you have a convergence problem. If you go into the setup menu of your TV, there should be some settings to adjust the red, green and blue hues and re-position them so each color matches up. If this does not work or if you don't have a menu, your TV *might* have a circuit board with several plastic screws on it. These adjust the picture and it's a very tedious task to re-align each hue correctly.

My projection TV is an older model from 1995, which is probably why it has this circuit board in place of a convergence menu built into the TV.

If adjusting the convergence still doesn't work, you might need to purchase a new convergence chip.

With TV turn off Press and hold Vol- and CH- at same time ,wait untill TV turns on then you should be in service menu adjust convergence,BUT if when TV is on and you Go to menu then setup and you do not see convergence listed in menu ,you have a blowed fuse FL231
