How do you know the bulb is fine? Are the LEDs blinking together or alternating?

I have toshiba 50hm67 replaced lamp...tv worked, then quit working again, and giving blinking yellow lamp error light when turn on...after a few moments tv tries to turn off and back on


OK. I have this same issue. I replaced my bulb a month or so ago. TV worked fine. Then one morning I turned it on and it was on for a good while, till it went to a black screen w/ sound only. Lights were going through the reboot process as designed for 8 attempts before it went to the solid red light. From the red light, if I unplug and plug back in, the tv will come on for a given amount of time, which varies, and then cut to the black screen. A repairman told me that it sounds like the digital board is bad. He wanted $150 for the board and $100 labor. I cannot find anywhere where the board would be located or where I can purchase a replacement.

Ballast Board? it is what Powers Lamp, or CK Lamp Fan if it stops running and is not Keeping Lamp Cool

Bad Bulb?


the pins that protrude into the lamp compartment have a tendency to get out of alignment where the lamp will only make partial contact. It sounds like what youre describing.

Screen went black an hour ago, the sound is ON


Start by replacing the bulb. If thats a no go, check the ballast. Its a small circuit board directly underneath the bulb housing and is replaceable through the bulb panel. If those two don't work, comment back and I'll walk you through more 'in depth' repairs.

Sound but no picture


there are several things that need to take place for the lamp to turn on. first the color wheel needs to turn on ( if you can hear a whinning noise then this is fine) next the tv will send a signal to the lamp ballast to turn on, and the ballast needs the 130v dc supply from the power board ( simoly remove the lamp and reinstall the lamp door, turn tv on, and if you hear an arcing noise from the ballast you know this is fine too. the board that controls all of this is the dmd board. so if the color wheel works, ballast starts then i would replace the dmd board....

There is a lamp driver error in your TV set. Most likely the ballast circuit for the bulb. Depending on who you take the set to, you will pay anywhere from 300 to 500 bucks to have this set repaired. This is why i recommend an extended warranty on all of these types of TV sets. This repair will involve replacing a board, and it could be one out of three of the differant boards that control the lamp. good Luck.
