Question about Philips DVP642 DVD Player

Power supply blew U301 (5M02659R chip)

Worked flawlessly until one day on power-up, the 5M02659R chip U301in the power module exploded, melting off pins 1,2,3 of its DIP8 package. Where can I get the power module cheap to try if the rest of the unit is OK?

    No 3.3V but I noticed +12, -12, +5V, -24V. However, the display module connector has also STDBY pin, S5V and AC1 and AC2 of unspecified parameters... which is a bit of a pain to figure out what it should be and if I don't plug in the display module I may not be able to get the buttons working and / or remote control. I don't feel like tinkering with it as this is a cheepo machine. Thanks.

I don't know where you can get a replacement module, but this dvd player uses very standard voltages (3.3, 5, 12, etc). If you feel up to it you can power it up with a standard desktop ATX supply. It's just a matter of matching the proper wires. I do believe they are labelled in the player.

I would first double-check the "known good" power supply. If there is something bad wrong with the MB, it could have blown the fuse in the power supply. I have seen very few fuses on motherboards, they are normally in the power supply. If the power supply checks out OK, then double check the connectors between the power supply and the MB.

Look for a fried (possibly exploded) transistor or diode on the power supply board. In particular, look at the transistor mounted on a heat sink (metal radiator block) between the fuse and the largest transformer on the board. It may also have a damaged regulator chip driving it. Modern TV sets operated by remote controls generally have the power supply split into two sections - standby and main. Your problem is most likely in the main section.

A voltage sniffer won't tell you much - most sets have power right up to the fuse on the power supply board. If the fuse is blown, don't bother replacing it until you find out what blew it - you'll just waste another fuse. I generally start by doing ohmmeter checks (power disconnected!) on the diodes and transistors - anything reading less than 1 Ohm is probably fried or is being shorted through a transformer winding by another fried component. Other readings must be interpreted according to the circuit design.

The problem can be bad backlight inverter board or the 24vdc power supply for the backlight inverter is not working, it is easier to look at the power supply module than to get to the inverter board, These are the two most failure parts in LCD TV. Look for bad capacitors in the power supply first or burnt parts.

LCD monitor stopped working on my CPU but works on my Brother's


Definitely some electrolytic capacitors are blown inside the monitor in power supply module. Open it and observe any of them rounded on top, replace with proper ones.
You see, controller operations with VGA and DVI inputs takes different current from the supply, that's why it may take different time until PWM chip in the power supply will decide it is time to shut down before getting smoked.
Replace capacitors.

Monitor fuse keeps blowing


There is definately a shorted component that causes the fuse to blow. Nomaly the ceremic capacitors are the cause of the problem. Check to see if there is visiual dark or burnt ceremic caps with label sameting like this "SCK 083" near the fuse area and change it. Hope it helps,cheers.

My motherboard BIOS is not starting


look for the CLRCMOS or CLR or JBAT1 terminals. These are the cmos settings and may need to be cleared, so refer to your motherboard manual for which one you have. Although what has probably happened is that when the PSU blew it may well have shorted the cmos chip which cannot be repaired, or damaged the graphics.
