PoisonJam Posted February 5, 2008 Report Share Posted February 5, 2008 Hey, all. Bit of a longshot here but I know we have some HDTV gurus. I have a Pioneer Elite Pro-610HD RPTV, and I'm afraid she's dying. Periodically my screen will get progressive brighter and brighter over the course of several minutes, and then give a sharp blue flicker (sometimes accompanied by an audible "POP") and return to its normal state. This happens on both inputs, and regardless of source (Xbox, cable box, DVD player). Sometimes it doesn't happen for several hours, while other times it happens several times an hour. It's been going on for a few months now, with no increase or decrease in frequency. Any ideas on where I can start looking to troubleshoot? I would love for it to be just a dying lamp or something because that's easily replaced, but it doesn't sound like it. Anyone else experience something similar?

foogledricks Posted February 5, 2008 Report Share Posted February 5, 2008 Pop for me indicates exploding lamp. but since your TV still works, that is not what happened. Hmm. Quote Link to comment Share on other sites More sharing options...
JTello Posted February 5, 2008 Report Share Posted February 5, 2008 I have no clue. Just brainstorming,... could it be something wrong with voltage regulation, and the sharp blue flicker electricity? That would seem like a potential fire hazard to me. I think I'd get it checked soon, just to be safe. Quote Link to comment Share on other sites More sharing options...
Josh Posted February 6, 2008 Report Share Posted February 6, 2008 That's a capacitor starting to bug out, at least that's what it seems to me. Some sort of capacitor/limiter that's failing and hitting a backup. Quote Link to comment Share on other sites More sharing options...
exile Posted February 6, 2008 Report Share Posted February 6, 2008 How old is the set? Usually the convergence board blows around 8 years and the power supply board goes in the 5-6 year range. I'll bet it's a power supply. There is no bulb in the CRT RPTV world Quote Link to comment Share on other sites More sharing options...
PoisonJam Posted February 6, 2008 Author Report Share Posted February 6, 2008 Thanks for the suggestions, guys. Now that you mention the power supply, I recall that the first time I noticed this happening was right after a power "dip" over the summer, where the A/C kicked in and the whole room (including the TV) dimmed for a second. It was right after that that the TV brightened to the point where I was thinking WTF?, and then flickered and went back to normal. It sounds like that power dip did something to a board somewhere. I'll have to find a reputable repair shop around here to come take a look. Thanks all! Quote Link to comment Share on other sites More sharing options...
