thanks very much about your technical support.but i solve allready the problem of LG LCD TV MODEL LT-15A10 TROUBLE; no picture with sound, i replace the socketed ic SDA555XFL62 PINS. THANKS... LODIVAR.
I just bought a 32" dynex lcd and saw that i couldn't program my two $5 ge remotes to work it. From reading in this forum and others I'm not the only one with the problem, I thought I was stuck with only the dynex remote. But the dynex website tells you how to get universal remotes to work,
It tells you to try the codes for Orion, Emerson, Memorex, Sansui, Sylvania, Zenith. The second orion code worked for me. both my ge remotes look and work the same but one uses a four digit code and the other uses a three digit code. I used 0135 on one and 135 on the other. There is a good chance that if you try the codes for the brands dynex lists you will find one that works. The 0135 or 135 might work for most dynex tv's.
If you have a ge remote and haven't programmed it for volume punch through you might try it. It allows the tv volume to be controlled using the ge remote even when it's set to something other than tv.
It looks to me like you have a possible power supply issue (poor brightness on screen, shrinking of the picture, and initially no picture) This problem may put you in danger of electrical shock, so I would suggest that you not try to repair this set yourself. I would suggest that you take the television to a television repair shop.The power supply issue could be a low power or a high power supply problem.
A lot of times the dc jack where you plug the power cord gets loose conections after so many times of use,if that is the case the set nneds to be open and the jack resoldered,sometimes is the ac adapter that is intermitant ,try twisting the wire to see if it makes any difference.If your tv looses power when using batteries you might be looking at a broken board.
