A tech would have to open it up and try boards next time.

Few months ago our older Samsung HL - s6187W would randomly loose sound, local tech said to change the lamp. Well for whatever reason that seemed to fix the issue (odd as it sounds but it did fix the issue)....Fast Forward...sound would go off for a few seconds and then the set would shut off, changed the color wheel as tech said that had to be the issue, it kept happening even after that fix.
Now the TV just shuts off and back on off and back on, sometimes it will stay on for a few minutes, but mostly just on and off until I unplug it.
The lamp cover housing is on tightly and the little switch is where it should be.
Unit was fully cleaned and dusted, none of the capicators seemed to be bulging.
Help, I don't want to have to buy a new TV at this time, and have already spent $75, on each tech visit as well as lamp and color wheel around $160.
I'm also being hopefully it's not an expensive fix and someone can help me troubleshoot.
