I have the same tv with the same problem. Not the power supply, not the inverter boards. I'll try a used main board and let you know. Did you get yours going yet? If so what was the problem?

Sound but no image on Hitachi 42pd5000


Two things need to be checked. The ballast board and the T-con board. Shine a flashlight on the screen with the TV on...If you see a faint picture moving, then the T-Con board is OK. The ballast board for the white backlight is bad. If you don't see a faint picture, then the T-con board is bad.

No picture, no menu, black screen, no raster, sound ok


From your detailed description, it sounds that the main chroma processor IC has damaged. Raster means nothing, but the lighted screen that appears, when a TV is switched ON. For some brands, there will be a blue screen; when there is no signal input, and some others will have a bright white screen with some snow.
I advice you to contact any service technician, to get this TV repaired. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

Sony tv mfm ht75w tv doesn't stay on, works for 10min sometimes,, other times only sec. i opened it all the caps seem ok, any ideas


Please clarify whether the entire tv powers off or only the screen turns off and you can hear the sound so that we can continue with the diagnosis. Sony LCDs are notorious for backlight inverter failures.

Just out of warranty Dell TV W3706MC,two years old


Sounds like a bad video board. No easy way to fix a bad video board. It needs to be replaced. That is why the repair shops will not fix it; they do not stock video boards for all models. And it is a pain to track one down all of a sudden. Once a warranty is up, you are running on bonus time. Electrical components have a definite lifespan. It is possible to recover some money by selling it "as-is" online somewhere. You could get 200-400 for it broken, pretty easy I suppose.

Screen white tinted, horiz lines, then shuts off


Not acutally a solution. We are having this EXACT same problem; it started this week. Let us know what you are having done. I've called Toshiba and service reps but they are all quoting a price which is almost half the value of the tv. Have you been able to fix it? We are pretty upset since the 2year warranty recently expired. Obviously, it seems that others are having this problem as well. Email us: briamanda@comcast.net
