\015\012"moves to 6 different homes and not one service technician call has ever been needed" (sic)
\015\012well it maybe now that it may make up for it.... :(
\015\012This could be your color engine, it may also be your color wheel? even a PSU problem, however unfortunately these symptoms you describe, are symptomatic of many many many faults. This realistically precludes diagnosis via, a forum, and one really must examine a set before a determination could be made, well unless a "Clear Cut" fault was exhibited, this one is not. These units never had any "Weaknesses" so to speak, and were/are a reliable set, though very out dated now. Once they start to fault, it is the "Thin end of the wedge" so to speak, and repaired units will usually fail again with 12 - 18 months. (According to statistics)
\015\012\015\012With this symptom, it is impossible to tell what the exact "Cause" of this symptom is. The LED's do not tell us what is wrong, sometimes it may indicate the "Area" in your case it is the X board. BUT thats NOT where the "Fault is" thats just the part that is affected. T What is happening is that you have a fault in the set, that is potentially very bad, and the Power Supply senses this and attempts to shut it down, now when it shuts down, the fault clears momentarily, and so the PSU, again tries to power up, sense the fault and tries to shut down again, we call this a Hic-upping Power Supply, and is often the symptom of a much larger underling problem. These days unlike the "Old" analogue days it just isn't realistically possible to fix anything but the most basic of problems with todays sophisticated units. This is quite apart from the Safety aspect, any unit that can cause a firs or have an explosion, or both, is NOT to be treated lightly, and and the repairer, of the unit is legally responsible, another thing to think about. Also, one must have tools, a Multimeter, a soldering iron, a deslodering iron, an oscilloscope, a signal tracer, tools, and most important of all, a Service Manual, without which, there is no way to even begin to understand and fix it, and more importantly Program it, AFTER it has been fixed. As these days a TV, is a PC, a Tuner, and an HDTV Monitor, and more, all in one. in the "old" days TV"s were more, rudimentary, and built to last for 20 years, and a "Parts" supply was set aside. They usually used to fail for only a few reasons, and they while still difficult, were less difficult to repair. Electrical knowledge was transferable, and they could be and would respond to, This-is-the-symptom-This-us-the-Fix, But that no longer applies, as now, it can be a Fault on I squared Bus, or "Sensor" failure, or it simple may have "Crashed" just like a PC, It could be a Diode go bad, and that will stop the whole thing. You see, in the day, the sets were Very "Fault Tolerant" because they were Analouge, and a faulty, component, or more sometimes, the set would always diplay something usually, and when they didn't it was one of only a few things, sure there are always the horrid ones, and there are pleanty of those, but all in all it was quite easy. But with Digital Electronics, it either goes, or it doesnt, there are usualy few half measures. I mean thats the definition of logic either going or not. So it can take very little to completely paralyse a set, and generally give the only sysmptom, it can, by not working, usually No picture, or the like. So you, see the list is endless almost for any given SYMPTOM, as that is what is being seen, not the cause, as I keep going on about. Also any fault, usually involves the Power Supply, it is either the cause, the cause of the damage, or it is damaged. or ALL of them. Then after you have done the electronic repairs, you then must program the set to work, and align, and set up in general, any one of those settings missed or done wrong, back to square one.\015\012 So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else
1. the moving could have thrown the color guns out of sync.> your TV unit will need service .
2. the horizontal out put circuit and or the vertical sync circuit may need to be serviced.
3. Your TV may need a TV technician to look at it to determined the fix.
Checking the main board with schematic and Oscilloscope for possible fail components is what will be needed to fully resolve your issue.

My Vizio plasma vp422 made a loud pop and went off. Now it won't come back on. U can turn on and the vizio display turns from orange to white but nothing else. Also u can see the little green light in the back is burning. I have removed the back and don't see any visible damage such as blown capacitors. Also I checked the 4 little white fuses and their is continuity running through them. I don't really know where to start looking next. Would it be one of the boards? Is there any way of checking

I have a Samsung HLP 4674w DLP. The picture started to lose color and look like a negative image. Then it would get scrambled and eventually go out. Powering on and off sometimes fixed it, but only temporarily. Sometimes it would also turn off and on by itself. I thought it may be the lamp so I replaced it, but it did not fix the problem. Next I thought it may be the color wheel so I replaced that, but the problem did not go away. Also when this happens the Power switch will not turn the TV off.
You need to change the lamp out, it builds up a internal resistance, and pulls your voltaged down, it will get to the point where you TV will not come on at all. Replace your lamp, you can get one at ...
