Question about Toshiba 57HDX82 57" Rear Projection HDTV

1 Answer

Grainy picture I have a Toshiba rear proj. t.v The picture is grainy and i cant get a d.v.d player or any game console to work. The t.v is about 5 yrs. old and never had a problem before. When any of the above are turned on i get a blur for a picture.I was told that maybe the tuner needs to be replaced. If this is true is it hard to replace or is it something that can be unplugged and put back in.

Hi and welcome to FixYa,

Initially, some ideas you may want to try/consider:

  • other than the TV, all switched off and unplug. Try evaluating the reception of any/all TV channels;
  • if quality is bad, either the tuner (least likely) is bad or a problem with your cable system/provider;
  • if the quality is good, then either the DVD or the game console has an RF modulator that interferes with the Toshiba's reception;
  • if the grainy picture is when using the Audio/Video inputs, then it would not be the tuner but rather the video processor;
  • should the tuner really require replacement, it would be relatively easy since it is a single block/assembly with a couple of pins and a mini coaxial connector;
  • best approach would be to reference a Service Manual. Pls bear in mind that voltage check requires the unit to be powered on and therefore exposes you to potential electrical hazard.
Check and perform preliminary visual or necessary inspection. Pls post back result(s). Good luck and Thank you for using FixYa.

SONY rear projection TV - Whites have started looking "snowy"


This is your Picture tubes getting very weak.( low in emission ) You have three in there and I guarantee they are no longer available so I would start thinking about investing in a new set, but use that one until you can't stand it anymore.

Fuzzy Picture


Fuzzy is a funny word. I never use it to describe a picture problem. That because fuzzy can go too many different ways. There is snowy fuzzy, blurry fuzzy, grainy fuzzy, and demodulated fuzzy. If the set goes out of focus intermittently that has something to do with the focus ciruitry. If it goes grainy that is a front end problem, usually tuner related. The other types of fuzzy are generally associated with problems in video processing some where. So, which is it?

Oh, and BTW that unit has three small picture tubes in it, one red, one blue, and one green. It doesn't have a 'bulb'.

Video 1 is the only input that gives clear picture. I tried my playstation2 in imput 2 and 3 but it is black and white and grainy.


You probably need new cables for the PS2. This was my problem when we got a new HDTV. Worked like a charm.
