Good day friends, I humbly ask for your valuable help, since they gave me a 32-inch PRECISION LCD screen, it turns on well, it changes channels, it receives all kinds of inputs, a specific example happens when it is on the Blue screen and the same at 2 minutes or less begins gradually to "dye white" until it forms a curtain on the whole screen, achievement notice after it is all white that, a line seems to feed the entire curtain as it passes from side to side slowly and barely noticeable. I have changed the T-with 2 times for used ones which do not consist of me that they are in perfect operation, but they assure me that yes, I have reviewed the voltages of the T-con, the fuse is supposedly perfect, and in the DC circuit -DC I see the voltages 27v, 3.3v, -7.2v, 14.2v and the same input 11.9v, apparently all the capacitors work normally given that I do not detect them in short or open, the Diodes seem to respond well to the voltmeter. Any suggestions please? I appreciate in advance the help provided Slds,
