SOURCE: samsung le40a lcd - picture quality

Hi - I have some suggestions. The following factors effect picture quality:
1. Source (because LCD TVs have much higher picture quality than traditional CRT "Tube" TVs, the worse your source material, the worse it looks on a LCD TV).
DVD and Sky/Digital TV should look excellent on this TV when connected with a good quality Scart lead (nothing too expensive, but a Oxygen Free Copper Gold lead may help) directly into one of the TV's Scart inputs (avoid using "switching" boxes for multiple equipment).
Also, bear in mind that this is a HUGE screen (40 inches I think) and will REALLY show up bad source material.
The best advice I can give is, if you have HD-ready equipment use HDMI connections for everything (ideally with an HD-uplscaling DVD player which will "improve" the quality of standard DVDs on the TV - I recommend models by Philips) and check that you are in "Movie" or "Cinema" mode on the TV.
Make sure that all of your equipment, like your Sky digibox, is set to 16:9 mode (not 4:3) aswell to preserve the true widescreen aspect ratio.
Hope that helps!

SOURCE: JVC LCD Lost Sound

Yes it is repairable

Do you get good audio from the headphone jack?
If yes, then it is the Audio Amp or some component in the Audio Circuit
If NO, then then Audio Switching IC is defective.

Expeens will depend on the person fixing it. expect $70-100 parts. I think labor is normally $80-120. so $150-220 total.

You can get a new 26" for that though. If the headphone works then the Audio Out of the TV will work. I suggest a miini system for audio out.

SOURCE: our samsung flatscrenn lcd has sound but no

If you get the vertical lines from the top all the way down to the bottom of the screen, it can be two things: the LCD panel is bad (very expensive) or the LCD panel driver board.

I have a Samsung LN46A630M1FXZA TV that had sound but no picture. I changed the T-Con board and now there is a picture but it is very light, washed out.


This is often caused by the Y-sustain board, be careful to drain all power before undoing the ribbons and are all secured before testing with power, I blew my whole board this way.

TV clicking on and off with colored screens and noises, not power supply capacitors this time.


Sounds like a main board fault. Contact any service technician to confirm. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

32" LCD SAMSUNG 2YRS OLD - PICTURE FOR 5 SECONDS THEN SOUND ONLY


I know it seems like it is a rip off but the diagnoses is probably right. It may well be caused by the digital controller that is mounted to the LCD Panel and is not sold separately so you need to replace the entire Panel whether the Panel it- self is bad or not. Cost of the LCD Panels are expensive and get much more expensive as the size of the screen gets larger. Sorry of the bad news.

Sounds like your LCD panel has gone bad.

If the unit is under warranty, take it to a Samsung repair shop. If it is not under warranty, go buy a new one. LCD panels are usually more expensive then buying a whole new monitor.
