Power ic damage


Check and replace the power regulator IC. But, before replacing and power up, check all the associated components in the main power regulator circuit, and make sure, all of them are OK. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

In asus P5GL-MX mother board the power supply regulator ic 2 piece has been damaged (short) how would i know plz help me


Hi if the regulator ic has been damaged in your power supply even you replace that there are some electronic component where also damage because the ic will not damage where there is no over voltage flow on it. This means there are some resistor or a transistor is also shorted it advisable to replace a new one than to repair your power supply. Because even you repaired it the performance and the life span of your power supply is not stable. So it better to replace a new one.

I have a proview lcd monitor model pl866s .What is the size of the power connector for the 19vdc @3068a psu?I have an extra psu with the correct voltage /current .Thanks Robert.


For the above LCD Monitor, I actually saw a small spark at the top part of the main board once the power input jack was connected. It prompted me to the exact location and when I check the SMD ceramic capacitor (that generated the spark underneath it) with analog meter set to X 10 K ohm range; it actually developed a slight short circuit. Replacing only the fuse and the SMD ceramic capacitor solved the no power problem in this 19" LCD Monitor. This Monitor uses the inverter IC (OZ960G), A1084-25CM (2.5 volts voltage regulator), AMC1117-3.3 (3.3 volts voltage regulator), ADC IC (MST8136B) and CPU IC (MYSON MTV312MV64).

If the IC your talking about has a designation number of IC601, the number is MX0841AB-F. Common regulator IC. Sony says that IC is no longer avaialable. You may get lucky and take out the entire G board and have ptscorp.com, or Tristate.com repair the board for you. Good Luck

Tv won't turn on


Your problem could be the Convergence board is loading down the power supplies and will not let the TV set come on, or the power/deflection board, part number AA94-08574A, or the STR type regulator IC, part number AA13-00105A. If you locate the convergence board, unplug the connectors, and see if the set will come on. if the set does come on, replace both of the STK convergence IC's at once. The part numbers for those IC's are STK392-40. You can get the original replacement IC's from MCM electronics for about 15 to 16 bucks a piece. Do not use the less expensive STK IC's as they are not the same. the replacement IC's should have the name of SANYO printed right on the face of the IC's. Good Luck

RT2250 Shuts down on its own after a few minutes of regular operation.


I have the same problem and it seems like it is going into thermal shutdown as ICs 104 and 106 are overheating which are fed from C138. All input source voltages seem to be correct and I do not get any voltage fluctuation from any input on the following regulator ICs. IC 106 3.3 VDC regulator is giving me 3.3VDC as a Output Source voltage and IC 104 5VDC regulator is giving me 5.0 VDC. IC102 15VDC regulator is giving 15VDC output and IC103 -15VDC regulator is constantly dropping voltage from the time of "Power On" until shutdown which takes about 5-7 minutes. I get right around -11VDC when shutdown occurs. ICs 102 and 103 are not overheating which leads me to believe that the IC 103 -15VDC regulator is faulty and putting a load on the other regulators which are trying to compensate for the voltage drop. I plan to replace the regulator with an NTE 969 replacement.

Set has power, but fails to turn on


Your going to need a schematic diagram and some troubleshooting skills here or a quilifyed repair person. This set has several power supply problems as well as sweep dirived power problems. The biggest problem is the STR (I dont remember the other #'s)(ie- STR#####) regulator IC It is alway the first thing that goes bad in these chassis. Now do not get a general replacement as it will blow out as soon as you turn on the set. I've been through this and a half a dozen regulators till I relized that the replacement ics do not have one last digit on the ic that the original did have!! and that one last digit made the ic completely differant. Another common problem here would be The Two filter capacitors off the sweep derived 15 or 18 volt lines Good luck to ya.
