Question about Sharp LC-37BX5M 37 in. LCD TV

Open Question

I have sharp lc-37bx6m lcd tv. After playing it for 2-2.3 hrs, in the right side, in 1/3 area, a wave comes and the waves turn into 8 horizontal lines after 2-3 mnts. If I turn it on again after 2-3 hrs, there is no lines and it works all right. But after 2-2.3 hrs, again those lines appear. Technisian told that its a logic board problem. Do I really need to change the logic board, please guide. Also, please tell where can I find it in India.

SOURCE: TV No Picture

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

SOURCE: Horizontal green line appears on screen

my maxent plasma tv has the same problem but it has green and red lines. I found out that hitting the tv from the back works. It used to last a long time but now i have to get up now and then to slap the tv on back with my hands! anyone with a long term solution?

SOURCE: green vertical line on the right side of screen

Warranty still alive?
Hope so; the problem could be an expensive one.

The screen appearance is controlled by allowing light from a backlight through by turning pixels off and on.
This switching is done by a matrix that turns on vertical and horizontal pixels of the right shade at the right time to produce the image you see.
One of the control elements for the vertical that controls the transmission of green light from the backlight, has died (no longer switching off and on when told) and these are normally a part of the LCD screen assembly itself and not easily replaceable.

I would be talking to Sharp - this shouldn't happen in 6-7 months of use.

Horizontal,wavy lines on sony xbr4 52" sony lcd tv


hi,
check the ground connection of your house wiring. fist of all remove all the external input like set top box, cable connection, dvd etc from the tv. Then power on the tv and watch is the wave is there or not. if it there then ,if the tv power cord comes with three pin connector then remove the earth connection on the wall outlet socket to which you connect its power. the connect the power and switch one the tv.
if the wave will not appear then connect external devices (set top box, dvd etc) one by one and watch which device produce this wave in the tv. also check the ground connection of that device which produce this wave.
If all these will not help full then the SMPS power supply of your tv have some problem. Normally this type of complaint arises due to the faulty Main filter capacitor. you can see it in the power supply.. It will be the big capacitor according to others. Normally There will two or more. replace the same. will solve this problem. if you need any more assistance feel free to contact me through fixya
ok

VIDEO TAPE WHEN PLAYED WAVE AT THE TOP OF THE TV SCREEN


This is a common problem usually seen when playing copy protected tapes. The part of the picture affected is normally off the top of the screen. Sometimes the problem is also due to the VCR itself and differences in tapes. It's also possible for the TV itself to be causing this, although you would probably also notice this flag-waving (that's what it's called) on regular TV viewing if that were true.

Sometimes increasing the height of the picture can push the affected area off the top again. But this can also cause you to lose part of the picture you want. Also, the height adjustment may be difficult to find as it's not something normally used. On some TV's it's a small pot somewhere on the board, but most newer sets have electronic adjustments through a service menu that you need to know how to access.

I'd suggest trying another VCR first and play one of the tapes you know shows the trouble. That might be all it takes. Then consider trying to increase the picture height if it's just a small bit at the top of the screen.
