Samsung CL-29D8W TV with flashback stripes.
Good evening: Do you know the chassis it is? .. At least per model I did not find diagrams ... (The + B can be 130 volts and the 200 is for RGB transistors, of course you have to measure it after the corresponding diode ) If the 200 volts is missing, the fault that appears on the screen is: White screen with a lot of brightness and trasos
hello I already did other tests, I already check trc voltage and arrive approx 198 v. One curiosity I found is that after desoldering the trc card and connecting and turning on surprise TV, it works fine. no backslides and with the screen at 300 v and the image settings work. but turning the TV off and on returns the problem, the same when desoldering capacitors and changing some. and turning on tv looks good again, but when turning on and off the problem returns, the commentary of fellow jesus I will still check and comment later.
Friend I forgot to tell you that this effect is also produced in some cases by the screen soke.
Apparently it is the flay back that is causing problems. I have graduated in approximately 320v. even if the image looks very bright and it becomes out of adjustment again. The screm button, when turning on the TV causes intermittent and then opens the normal screen but after a few hours the TV returns to normal brightness. but when you turn the TV off and on, you can no longer see it and oh, that adjusting the screem again. Now it is no longer set to 320V, it is now set to 350V and I will continue commenting. fatty With respect to the soket components well. Capacitor and resistors. Without diagram very complicated to work.
