Blue light remains lit but lose picture. no other indicator lights flash. if i unplug the tv it will restart but lose picture again after half hour


I have a toshiba 50hm67 tv and with mine the blue light would come on and I would hear sound first and then the picture would finally come on... this happend for about a month.... next the yellow and blue light would come on but the pic still wouldn't come on until it clicked off and on by itself for about 10 min this went on for about a week. All of a sudden last night the red lights by the power light started blinking. No tv now and when the tv shut off it said lamp not working.

Have a Toshiba TN55V71 whose color seems to come and go. Sometimes it is just pea greens, yellows, and blues. Other times, the color is flawless with brilliant reds and oranges. What gives?


That usually means the color wheel is going bad.
If you like the Tv and you are handy it is fixable. If you are not ready for that, give a repair man a call. It is worthe it.

Thank you for the chance to help.

you will need two convergence ICs they are both STK392-110 and you should also order four 2.2 ohm 2watt resistors. You can get replacement ICs and resistors at the following link with free instructions.

Red light bflashing


Sometimes a power surge will cause a projection back TV to shut down and flash like that. If you unplug it from the wall and let it sit for a minute and then plug it back in, it should reset itself. If that doesn't work it will probably have to be serviced. If it does work, make sure you get a nice surge protector so you don't fry your TV.

Toshiba TN55V71 55 in. Rear Projection - Damaged


Hi. If the convergence is out but uniformly then chances are its not electrical problem more likely to be physical see if the 3 small crt tubes are loose & can move about. Or was your stuff insured during the move if so put in a claim.
