Question about Yamaha DRX-2 DVD Recorder

Open Question

Power supply drx-2 total damaged, tea 1507 burned and fet p3nc60 shorted 0 ohm also r3318 (47 ohm) defective.

My solution : replaced ic, fet and also optocoupler and resistor.
But no good result.
5 Vreg is to lo (1.5 V) and 12 Vstby = 10 V. There is also no display and the Fet is going very warm. Only the rec. button on front blinks (weak).
Most all components in live part are checked all good. Secundary fuses and Fet 7302 are all good.
Do you still have any repair idea ?

with kind regards,

Unplug all speakers rewire the speakers making sure not to cross anything check all wires for shorts (cat bites etc) Make sure that only 8 ohms (one speaker ) is on each wire or the ohms that are specified on the amp. In electronics 2 eight ohm speakers in parallel becomes 4 ohms total and will put the amp into protection mode. watch for stranded wire pieces crossing to the other wire. If it still has problems it may need to have the amplifier transistors/ics replaced. While the cabinet is open look for electrolytic capacitors that are bulged or split and replace them.

Lightning damage


Replace the parts with the original ones, a .5 ohm difference on a resistor on the video circuits will cause the unit not to work correctly.

It sounds like the power supply has failed. A good idea would be to check all components in this section, in particular the IC regulators, as well as diodes and capacitors for leakage and/or short circuits. Look for bad solder joints, burnt spots around parts, swollen capacitors etc. The ICs in this series (especially those in the power area) are known to cause trouble, so check those first. Also check resistors (fusible, high wattage (usually white block types) and normal colour-banded types) to see if any are open circuit or have gone high (resistors don't usually short circuit - they either go open circuit or change their value).

To ensure long-term reliability, it is a good idea to replace ALL of the electrolytic capacitors in any power supply as well as any blown/open/short-circuit parts. Capacitors are the most likely culprits for problems, so when replacing them, uprate their working voltages and/or values where necessary. If none of this restores your machine to full operation, take it to a service centre and seek a second opinion on this matter.

Our panasonic dvd recorder keeps "saying" self check for days now. We can't use the machine. Nothing works. We put off the electric and put it on again. With no result. What can we do?


From experience - it is probably the main IC (IC1) in the power supply - it may have become defective somehow, or been partially destroyed by an increase in voltage going to it. The power supply is the biggest problem area in this series of DVD recorder (the Panasonic DMR-E55 is another model which has a similar problem). My suggestion would be to check every component within this ciruit for leakage, short circuit/open circuit, as well as the IC itself before replacing any parts. The number on the IC should be type STRxxxxx (whatever the number is) and this device should have 5 pins or more. I also recommend replacing all of the electrolytic capacitors in the power supply to ensure long-term reliability.

You have to measure where the short circuit comes from.Usualy the fault is in the power FET ( if so the IC nearby must be replaced to) or the rectifier has a short circuit.
If the FET is broken always measure the high ohmic resisters nearby for open circuit.

My DVR5013 has a faulty power supply as well, I replaced 1 cap and it was working ok for a while but now it looks like the FET has died, another on order..

Has anyone got a circuit for this beasty?

Seems that the major problem with these units is always the Power supply, low quality, cheap and nasty.

Sounds like a faulty diode on the power supply. If you know a bit about electronics then investigate, if not find a competant technician. Good luck.

The Power supply was made to fail on this model. I would recommend using a Regular Computer Power Supply. It would cost $20 to $30 dollars for a brand new supply if you don't already have one to use.
