Hello CAPTKING,

Your TV specs as a flat screen and not a projection TV. So this diagnosis is for that of a flat screen CRT. It appears that your filament voltage might be low or the CRT cathodes have excessive oxidation on them. These are the two primary reasons for this type of failure. The secondary reasons would be low video signal, problems with the screen, focus, or control grids, or low anode voltage (which would also cause picture shrinkage). I would suggest that you take the TV to a qualified TV repair shop to have the work done.

Have them run a diagnostic on the CRT with a CRT analyzer and check the CRT voltages with the TV connected to a video analyzer set at the normal configuration for a color picture.

I hope this helps

Thank you,

Good day!!!

Sorry but I can't see any previous questions from you to my email but anyways lets proceed to your problem..

If you are watching TV shows and the picture is ghosting kindly try to play a DVD movies or anything that having video on your DVD if the picture is fine when you play a DVD movies your TV is in good condition you don't have to worry about..If the picture is fine when you play a DVD let me know and I will give you next step of troubleshooting..

However if you play a DVD but still picture is ghosting there something wrong with your TV..

If you are using DVR then when you back to TV it become ghosting..It is possible that you hit the wrong button on remote..you can also try to restore factory settings to correct all possible wrong set up and also to to auto scan your TV to get back all channels clearly..

Hope it helps..

regards,
chester

Trying to connect my inspiron 15 to my toshiba 32af44 and i can't get a picture on my tv. I have bought a pig tail that goes from VGA(the lap top side) to s-video/audio-video cables(tv side) but still...


> I have bought a pig tail that goes from VGA(the lap top side) to s-video/audio-video cables(tv side)
A simple pigtail won't convert VGA to S-video. The VGA output consists of separate RGB lines and horizontal and vertical synchronization lines.
If you have an adapter that really converts VGA (this output has no audio path) to S-Video and audio lines, then you probably just need to re-select the input through the TV's menu system.

Daytek DVK2001S will not read "PAL" DVD.


Yep, your dvd player may be capabile of producing a PAL video signal, but that does not mean it will play DVDs from a different region. If you require that functionality, do some research on the internet to find a player that will play any regon before making a purchase decision.

Toshiba 52" REGZA has a grainy picture


There is no easy (read: cheap) solution for this. Especially because your TV is so big, the only thing that will look good on it is something that plays at the very least 720p HD output.

I don't know what your DVD player model is, but you want an upconverting DVD player, and even then, the quality will not be full HD. The only thing that is full 1080p HD on the market today is Blu-Ray, and game consoles like XBox 360 and PS3.

As for the sports, it depends on the TV you bought. If the deal was too good to be true for a 52" TV, you probably got one with a low Hz, or a high refresh rate. This means that the images played don't update quick enough for high motion video like action movies and sports, which is why it's blurry. Mine has a 3ms response time, by comparison.

Hope this helps, please rate me.

Good day.
Your units problem could be traced down to the loose contacts in your chroma and crt circuit sections. Have these sections resoldered. This should resolve your problem.

response is highly appreciated.

PS2 Picture Problem


Hi MG86,

Most PS2 games are dark and auto brightness controls will casue your LCD tv to brighten up automatically in response the dark video coming from PS2 games. I suggest you get into the menu settings of your TV and find a setting that will shut off the auto picture controls.

Toshiba 51H83 51 in. Rear Projection pisture issue


I have a wild guess. I have the same tv and channel 72 is the proper channel to watch tv on. I don't know why, but maybe try channel 72 instead of the usual channel 3. Good luck, maybe a quick fix, maybe not!

Picture too dark


You didn't say if you are receiving an off air picture or cable or satellite. The reason the commercials look good is because the local station (or source) transmits them "in the clear", that is, without any enhancements to the video signal. Network programing or local newscasts are sent through a device which inserts a reference signal in what's called the "vertical interval". You may have seen this as a series of flashing dots or pulses at the very top of the picture. There's a lot of information packed into the VITS (Vertcal Interval Test Signal). One of the lines contains a reference pulse for video which is set at a certain level. Your TV sees that level and automatically adjusts its circuitry accordingly. What I suspect is that your set is out of calibration and is pushing down the video signal because it is not "seeing" the level properly. A video alignment should correct this and can be done by a good repair facility. Hope this helps.
