Panasonic DMR-E75V VCR/DVD Recorder combo player - Lost power

I recently purchased a Samsung VCR/DVD combo player. I brought it home and it had no power I'm trying to repair it and currently have another thread open as I work on it (HUGE thank you to those helping out, hopefully close to a solution).
Soon after bringing home the dead Samsung (before I thought to post on here to try and fix it) I found a Panasonic DMR-E75V VHS/DVD Recorder combo player. This is even better as it allows you to record VHS straight to DVD...well, it would if it worked.
This time I was at least able to plug in the player before bringing it home to make sure it had power! (Ha! Getting smarter I thought to myself). It DID power on but I was unable to do any other testing before purchase. Once I brought the player home I took off the lid and did a visual inspection. She was pretty dusty/dirty inside and I noticed 3 capacitors with issues. (See attached photo's). One is obviously leaking and two others were bulging. I've circled the two on the power supply side in red in the attached photo. The third capacitor was on the VHS side of the board (I can post a pic if needed).

I replaced the 3 bad capacitors, cleaned out all the dust/hair etc. and plugged in/ powered up the player. I then gleefully played some VHS tapes and DVD's with no issues for two days! Ok, there was one small issue. When I pushed the VHS tape into the player (gently) it would take the tape but then jam and eject before fully loading the tape. It was almost like the carriage would try to lower the tape before it was in all the way. A second try at loading the tape always seemed to work though, and once it lowered into place the tape would play perfectly with no issues. On day 3 I decided I would take the combo player to my work bench to see if I could determine why the VHS tapes were jamming. I unplugged the player (which had a display/clock when I went to unplug it) showing it still had power. I moved it to my work bench, removed the cover and plugged it in to do some testing. DEAD. Nothing, no lights, no reaction whatsoever, totally dead. I thought it had to be a coincidence since it just had power before I moved it! I tested the outlet I was using and it was fine. I tried another known good outlet, same results...DEAD.

The obvious glass fuse in the system is not blown. Visually everything else looks fine. I'm wondering if changing out those capacitors fixed one issue but then "blew" another part that was "on the way out". Attached is a closeup photo of the power supply side of the system with the new capacitors in place.

SUMMARY:
System had power initially but 3 bad capacitors were present.
Replaced bad capacitors with new, equivalent value, caps.
System worked 2 days. Was unplugged, re-plugged in and suddenly had no power.

I was unable to find a service manual for this system online, unfortunately. The user manual is readily available (although not overly helpful here).
I'd love to get this machine working again. I have a multi-meter, capacitance meter, soldering iron and a somewhat limited knowledge of electronics. (No fancy tools like an oscilloscope). Any advice welcome and I'm happy to provide more photo's, info etc. Thank You!

 

Checking tracks and all looks good as far as I can tell. I have pulled the capacitors from the board and tested with a capacitance meter. All pulled capacitors measure fine, although the three 220uf 25v measured under 220 but still within tolerance range at 210uf. The two very large capacitors I left in the board and measured. They also measure fine. Photo shows power supply section of the board both front and back. I need to reinstall capacitors.
Any other advice on what to look for would be appreciated.

 

I soldered in all new capacitors (I tested them all before install with the capacitance meter, just to be safe, and they all measured ok).
I applied power to the board and measured DC voltage on the bridge rectifier. Results were 164.
I then tried to measure DC voltage on the two Zener Diodes located at D11158 and D11155.
I had the multimeter set to 200 DC. I applied the positive lead to the anode and the negative lead to the cathode.
D11158 measured -01.3
D11155 measured -09.8
(attached is the manual for my multimeter so you can see it's functions, etc.) Let me know if I did anything incorrectly.

Device number for the controller IC is MR1521 (number 1744 is above that). From what I'm seeing it's a MOSFET.

Thank You for your input! It is greatly appreciated.

 

What would be the safest point to use for Ground when measuring the voltage on Pin 4? I'll be measuring from the back side of the board as it will be easier to access the pins from there.

 

Lol, well I did say I had "limited" knowledge
Ok, with the multimeter set to 200 DC it measures a steady 9.8 on pin 4 of the MR1521.

 

The other part on a heatsink is FCQ 10A06 (N4F above that) labelled on the board as D11270. It appears to be a Diode Rectifier.
I'll have a look at the capacitors on the secondary side tomorrow and do more testing. I'll report back.

Thanks!

 

I plugged in the VCR and noticed a light buzzing noise. Prior to this the VCR had been completely dead so I went ahead and reassembled the system. I plugged it in and, lo and behold, we have power. Switching out the capacitors must have done the trick. I noticed that the fan at the rear of the case is not working at all so I'll need to test/replace that.
Hopefully we are good on power from here on out but I still have an issue. When putting a vhs tape into the cassette carriage, the carriage moves forward and lowers before the tape is completely seated and jams. If I hold the carriage, to prevent it from moving forward, and gently push the tape in until it's seated properly, then gently push the tape forward the motor takes it and lowers it properly. What would cause the carriage to move forward before the tape is properly seated? Are the gears misaligned?

 

This unit still experiences issues. Replacing the capacitors did not resolve. It will sometimes power on and work, then spontaneously lose power and refuse to come back on. Leaving it alone for a few days may allow it to come back on later. I'm not sure what to do next to try and troubleshoot.
