magenta blotch when RCA 20F424T should show a blue screen
If this is the wrong forum, please tell me where I should post this question instead.
It's a low-end television, yes, but not all of us can afford much more, and the RCA 14F514T we already have in another room had been working well before I bought the 20F424T and it still does.
When we momentarily get a blue screen in changing channels through the 20F424T's ATSC tuner or its digital QAM tuner, or when I deliberately tune to a channel with no signal just to see the blue screen, a little to the left of center there can be a pink, possibly magenta, blotch about 1/3 the height of the screen and maybe 2/3 to 3/4 as wide as it is high. It appears only after the set has been on a few minutes, and sometimes it's brighter than others, and sometimes the area is the same blue as the rest of the screen. As the set stays on, the splotch can fade (not in front of our eyes, but it can be closer to blue with each tuning) and then get pinker again.
When we're actually viewing a signal, usually the colors are fine, but sometimes -- more often when it's receiving upconverted native SD material broadcast on an HD station (it has happened on both 1080i and 720p channels, but of course as an SDTV it downconverts to 480i), roughly that same area of the screen can have a pale greenish tint. The area subject to the greenish tint is not quite the same as that of the magenta splotch: it stretches from the top of the screen nearly to the bottom.
The greenish tint comes up infrequently, and the splotch doesn't interfere with viewing, but are they signs of more trouble to come? The set's return period at the dealer ends this coming Friday, so I have to make the decision soon. I'd return it just for peace of mind, but it's very heavy for me. I'm much weaker than the average adult man, and a dolly won't help with getting it down the front porch stairs nor with lifting it from the dolly into the car, so I don't want to lug it back on a whim.
[Adding a CECB to the NTSC set that it replaced (still in the basement) is not a good alternative. The OTA reception in that room is poor, and our cable provider is aiming to go all-digital around the same time as the OTA cutover, so we need a set with a digital QAM tuner to get unencrypted digital cable stations without renting a box after the cable provider goes all-digital.]
Thanks for any assistance.
