M-PEG VITRON DVD MAXTRON
M-PEG VITRON DVD MAXTRON and even GMC are very similar, used or MT.Maka sunplus chipset that all complaints of damage from two brands is almost the same.Here I discuss about the damage "BLANK" on DVD MAXTRON MAXTRON model 83000-5 and 683, only asessoris lights are lit, others Matot (off total).All the output voltage of power supply units are normal hinnga go to IC chipset (sunplus).First I re-soldered around the legs of the chipset, it turns out the lcd can be performed, open-close any running normally, but after about 2 minutes, M-peg manjadi hangs (not functioning total) and chipset temperature suddenly increased temperature (heat) . Optical was never able to read (reading).As in most cases happens to his brother (vitron). Immediately I check the path for the chipset voltage 3.3 volt, As a result, it turns out two IN4007 diodes and one transistor S8550 is very hot and cause the drop on this line.I immediately change into four components (two and two-TR IN4007 S8550) and its elco 220uF/16V and 10uF/16V.Meskipun if the measure look normal.Why is that, because a heavy burden for both transistors and diodes causes the component temperature rises, a result of leakage current in both the semiconductor is increased as well (near the point of maximum voltage semiconductor break).Setelahnyapergantian, the visible optical walk normally.Not only there, after about 10 minutes of walking, again I check all the conditions of the circuit, there are still problems, namely two in the power supply 220/35V elco join this suhunya.Elco increase in the output path - 12Volt on power supply block.Elco turn of the last two is the last process in repair this MAXTRON DVD case.Good luck.

M-PEG MAXTRON DVD and even VITRON GMC is very similar, using a common chipset or MT.So sunplus That all complaints of damage to the two brands are Almost the Same.Here I talk about the damage "BLANK" on DVD MAXTRON MAXTRON model 83000-5 and 683, only light asessoris that, other dead totalAll the output voltage from the power supply is normal to the IC chipset (sunplus).First I re-soldered around the foot-feet of chipsets, the lcd Appear cans, close any open running normally, but after about 2 minutes, M-PEG hangs (not working total) chipset and the temperature Suddenly Increased temperature (hot). Optics was never Able to read (reading).As in most cases Happens to his brother (vitron). Immediately I checked the line voltage to 3.3 volts chipset, Hence, the two transistor diode IN4007 S8550 and a very hot and cause a drop in this path.I Immediately change to the four components (two and two IN4007 TR S8550) and its elco 220uF/16V and 10uF/16V.So if seen in the normal measure.Why do so, Because a heavy burden for the two transistors and diodes component is Causing the temperature to be Increased, Hence the flow of leaks from both Semiconductor is Also Increased (to a maximum break point voltage Semiconductor).After changed, the visible optical running normally.Not only there Until, after about 10 minutes to run, I check back all the series of conditions, there is still a problem; the two elco 220/35V Participate in the power supply Increased temperatur.Elco this path in the output - 12Volt power supply on the block.Turn of the last two elco is last in the process of repair cases MAXTRON this DVD.Congratulations try.
