I have a toshiba 62HM15A. I had the light engine

Hello,

Have you tried checking the socket to make sure there is voltage present and that the contacts are making connection with the bulb. Sometimes melted plastic blocks the connectivity of the contacts of the bulb with the contacts of the socket. Use a voltmeter to check for the voltage on the socket contacts.

I hope this helps,

If you are using component cables make sure they are all connected properly( pushed all the way in and in the correct input). I have seen the red cable come loose several times and cause no red color in the picture. When you change the lamp it is easy to pull on one of those cables and cause it to come loose.

Often convergence issues do not require the entire board to be replaced. You can resolve it by replacing the convergence ICs. The part in question is STK392-110. You will need two of them and they cost around 10$ each. But replacing them is a pretty complicated procedure and I would not suggest it to someone without prior experience. A service manual should get you started in the right direction if you are planning to do this yourself.

PS: Disconnect from the power supply before you start the repair. Also read the legend, the hv circuits are denoted by a special symbol, so you will know what you shouldn't touch.

You may also need to replace the nearby resistors that may have popped the IC in the first place. Read the service manual for further details.

Good luck,
Sai.

It sounds like you need to replace the lamp. Take the lamp assembly out and inspect it. It will have a white smokey look or may be cracked if it is bad.

Have you replaced the lamp recently? If not the lamp is the first suspect on a picture that flickers...
