Poor picture Hi There, I have a Samsung LE32R74BDX which I purchased in September 2006. The picture has deteriorated recently particularly when it is first switched on, and appeared lifeless and dull, and would always improve within 1 to 3 hours. I had an engineer come out this morning and he identified the following:- 1) The Energy Saving feature was set at high and he turned it to Off. 2) He also adjusted the TV to Dynamic Mode from Standard. Both of these adjustments have improved the picture dramatically, but I have still some concerns which the engineer could not answer. Why is there a Energy saving feature if it cannot be used and must be switched to Off? I have also read that using Dynamic Mode is not good for the TV and can cause screen burn. I would welcome any thoughts and comments. Many thanks Michael

Summary


Should a customer express concern about one of the following:


* hesitations,
* poor or no start,
* deteriorated fuel economy,
and upon investigation diagnostic trouble codes (DTC) P1412, P0490 and P1335 are stored in the powertrain control module (PCM), the probable cause is a sticky exhaust gas recirculation (EGR) valve.


To rectify this concern, a new EGR valve with a stronger EGR valve motor and revised PCM calibration should be installed.

It sounds like the T-CON board problem, you can try reseating the connector first, the board is mounted under the metal shield which sometime can be difficult to get to.

Additional information is required for us to assist. Can you better describe what you mean by "poor image"? Are the colors separated? Is the picture out of focus? Are the colors wrong?

Please describe the picture or post a picture of the screen if you can.

Thanks,
Dan

Hi,

If you visit www.quinny.com, you should find the information you require.
If not, I have I 2006 September manual that I can email to you on a pdf format, not quite sure of how to do that via this site tho.
I hope that this helps.

Hi,

Hardware related, needs an engineer as not a simple fix.

Thanks

Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.

Try to change the screen resolution on your computer right click on the desk top properties then settings tab. If this does not help try adjusting the video options on the tv like contrast and such.

Good luck

this is because most new lcd tv's have a poor tuner built in and require a stronger ariel, to pull in the analogue or digital signal. Check that your ariel is freeview capable whether using freview or not, as these ariels are better at pulling in the signal, or do what i have had to do and buy a mains plug in signal booster from Asda for about £6.00, this did the trick, especially if you don't want to replace an ariel costing about £30.00
