    I have the same problem M50WH187YX1. I have a white screen with stationary black spots or specs and about 3/4 of the way up there is a solid black horizontal bar. Above the bar is the same white screen with black spots. Sound is fine, channels can be changed, but the white screen does not change. This happened interminttently for 6+ months and would come back with a power cycle. Now it will not work at all (only white screen). Any ideas?

SOURCE: "weak signal" on my RCA scenium

Hey! I have the same problem as you. But! this would happen only when I got a power outage. Unplug the TV for a couple of minutesand all was fine. For the last 5 day I have no TV. I have tried everything. All the out on the TV and I still get unusable signal. My rep told me to unplug for 24 Hours. Still didn't work. My menu option work as well and every time I put the TV on, off or if I change the input sound will come on for 2 seconde and stop. If I find the salution I will let you know. Gilles Ottawa

SOURCE: RCA TV flickering problem

Help! I have an RCA 40 inch HDTV (Model# D40W20). I've had it since 2005. Recently, the picture will flicker when I turn it on, but will stop flickering after a few minutes. My brother has the 52 inch model and his tv did the same thing before it broke down completely. Does anyone know what the problem could be?

SOURCE: dark picture on RCA Scenium 61 in DLP

Yes, the lamp will gradually get darker as it nears it's end. The rolling lines sounds more like the set is on a local channel for the cable hook up. If your local area has a channel 3 or 4 live terestrial broadcast simply tune the cable box output to the other one, the same for the tv.
If this is cable/local broadcast issue it will go away in Febuary when the NTSC broadcast ends.

I have the exact same TV and have had the exact same problem. I talked to a TV repairman who said it has to be my deflection board. I just found this out today so I am looking all over the web for a deflection board. I hope this helps! Tyson

SOURCE: rca 32 screen turns on but stays black

Theres no start-up signal being encoded, this means the interface board has an offset capacitive value. You need to test and measure the capacitors and npn/pnp transistors, along finding some open diodes too on the main board (interface). You have to test the capacitors under their operating voltage also to see at which point their breaking down. The problem is a 'load' condition on the main board. You can repair the board if your savy and you have test equipment or you can just replace the board. If you want to replace it e-mail me and I'll help you out....

I believe it is the digital projection chip that is beginning to fail. Causing white and black spots to appear. To repair this may cost more than a new tv. If you want to attempt it yourself check out the above link. Hope this helps

Sounds like the color wheel or lamp I would check the lamp first to insure thats its not broken as they can make a pop when they fail sometime (Breaking) then I would check the color wheel you will be able to tell if the color wheel arear has the noise coming from it. If you need more assistance let me know.

When I try to hook up my nintendo wii to an hdtv I get a black and white picture? The RCA cable only has 3 cables and the input on the tv has 5 outlets.. could this be the reason? how can I get it to work?


The RCA cable you are using is meant for standard resolution TV's. There should be a spot on the HD TV for the standard RCA cable. This will resolve the black and white color issue but unfortunately you will not get the benefits of your HD TV. Your best be is to get a composite cable for the Wii. You can get the cable from target or wall-mart but online shopping will typically result in a cheaper price.

I hope the info listed above has helped in some way.
If possible please rate this solution.

No picture, siren type noise as restarting


My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?
