Hallo an alle, ich habe zwei Problemen, eines ist, dass mein Deutsch sehr schlecht ist, also, ich bitte Sie, dass Sie mir in englisch schreiben durfen.(danke)
My problem is with a SHARP TV. The schema ist hier http://tibor56.hyperlinx.cz/index.php und in my http://www.urbiaclub.com (sehen Sie gastbuch).
The problem is a follow: black screen, sound ok, HT ok, digital modul and scart modul unit ok (I have swapped them) picture screen module ok, if I give more G2, the screen iluminates, with return frames, and a little image, but a very little image can be seen. SDA and SCL appears to be correct.
NVM, MEGATEXT IC, RAM Megatext changed, all currents are and voltages ok, through scart I have good image to another TV, but if I put a video signal from out to the TV, then happens the same, so it's something about the digital module, but it is not, sure, its is now working in another tv set. The megatext IC, have a RGB output with TXT and MENU signals, they are OK, if I connect there an TV (through scart), in this other tv appears (without sinc) the menu and TXT if called, so, all the problem is in something near the digital module. vertical pulses are present in the module, all appears to be OK, except the only piece I have not found and is the guilty. please, help me. i know I do not help here, but my german is bad and I can't understand some technical words., I'm moderator in a spanish forum like this (not as good as this :D:D:D:D:D:D:D)
thanks
