Re: power up

I followed instructions posted at
and I opened the unit.
I unscrewed 3 black screw on back, removed two side covers, then I unscrewed 4 silver screws (2 & 2) on both sides and removed the top cover. Then I unscrewed 4 screws (those four screws that hold the silver hlder on the board - they are down, so you need to use long screwdriver.
Carefully moving & holding HDD in the silver holder (moving it only little bit up from the board to see underneath on the board), and I was able to see 2 blown capacitors (with brown stain on top). They are C1261 & C1260 caps - ELNA 680uF RJF 10V.
I did not attempt to remove silver holder with HDD totally now.
In reverse order, I screwed everything back.
I ordered parts at support page for model SC-HT1500, then choosing SA-HT1500 - Main Unit. I found those 2 same capacitors; they cost $1.89 each. Shipping & tax came higher than price of parts. I
I already have soldering iron, and I will try to replace blown capacitors by myself after receiving ordered parts.
I will post my next message after receiving parts - approx. in a week or so.

Re: power up

Kudos to the person who posted the circuit board location and capacitor values of C1260, C1261, & C1262. My problem sounded exactly as described by the others in this post including the hissing (almost a squealing fact I thought it might be the drive beginning to fail, but alas it was not) before the final failure which resulted in the power light flashing on and off. I ordered the parts from Digi-Key without even opening the unit to confirm that my 3 caps had indeed failed. When the parts arrived, I opened the unit, went straight to the board under the HDD, and sure enough, those 3 caps had all leaked. With new parts already in hand, the fix took 10 mins to replace the 3 caps and seal up the unit. It powered up perfectly and is back in service! Total cost of repair was less the $4 including shipping. The DigiKey P/Ns are: 493-1494-ND (680uF 10v), and 493-1527-ND (1000uF, 16v). Note that the 1000uF that I pulled out of my unit was rated at 10v, so the 16v replacement should have a longer life. Thanks again to those that posted this fix!

Re: power up

At first teh red llight would come on then, some quirky soft chirping\squeeky sound on SA HT1500. I first thought it was the horizontal transistor, then when I later read about the capacitors, I was certain teh capaciotors were dead. The C1261 & C1260 caps had a slight brownish excretion.
Repair was done to are C1261 & C1260 caps and then it booted straight up without any issues.
I bought my caps from R.S. and the vertical type. Thanks to all who contributed.

Re: power up

I made this repair on my unit with 2 new capacitors. However, I had to bend the multipin jumper thing so I was afraid it would break if I keep moving the daughter board so, after replacing the first capacitor, I tested the unit, it worked so I put everything back without replacing the second cap. Well...everything works except the TVG feature. I redid the whole TVG setup but it still got no programming info. Not sure if this is related to the capacitor I didn't replace or not (hopefully not).

I'm thinking of opening it up again to replace the other cap. I was thinking of upgrading the HD while I have the chassis opened. Does anybody have experience with this? It's just a regular 3.5" HD. I imagine that, if you clone the drive, things should be OK but not sure what to expect. Has anybody done this?

Re: power up

Found this as a reply elsewhere on the net:

Re: DVR whined, wouldn't stay turned *off*, now won't boot
A followup: the DVR is now repaired. The problem was 3 bad radial-type capacitors in the power supply (which explains the three stages of the failure). The repair company gave us the old caps, which were made by Elna. All three have clearly leaked out the top.

IMO they overcharged us a bit for the replacement capacitors ($6 each for two 16V/680uF caps [online catalog price $2.10], $9 for a 16V 1000uF one [online price $1!]). It incurred the minimum labor charge of $100. But the repair was done fairly quickly and the unit is working again, so we're happy.

Seems like they talk about the same 2 680uF caps along with a 1000uF cap.

Will have to try the repair after the holiday weekend after I get parts.

When you turn it on The blue light flashes and it returns to the red light and will not turn on

This is a power problem from the unit. The unit receives power into it but does not supply the power sufficiently enough to get the unit to function well. This is why the blue light flashes when the initial burst of power is sent into the unit but due to lack of follow up power the unit fails to remain on.
Best get an expert to identify if the power supply distributor in the unit is bad or the ic which is responsible for the distribution is the cause.
Hope this solution has been helpful?

I bought a Sony BDV-E570 in US and it came locked for region 1. As I live in Brazil, I need to run region 4 dvds. Do you know how to unlock it? Thanks


Full procedure for a oneforall remote is as follows:

1. Press DVD
2. Hold the magic button until the DVD button flashes twice.
3. Press 0533

4. Hold the magic button until it flashes twice.
5. Press 994
6. Press Magic Key (don't hold)
7. Press 00189 (if your oneforall remote uses 4 digit or 3 digit codes, use less leading zeros)
8. Press 1 ( this sets it to key 1 - it flashes twice )

9. Hold the magic button until it flashes twice.
10. Press 994
11. Press Magic Key (don't hold)
12. Press 00255
13. Press 2 ( this sets it to key 2 - it flashes twice )

14. Hold the magic button until it flashes twice.
15. Press 994
16. Press Magic Key (don't hold)
17. Press 00095
18. Press 3 ( this sets it to key 3 - it flashes twice )

19. Hold the magic button until it flashes twice.
20. Press 994
21. Press Magic Key (don't hold)
22. Press 00221
23. Press 4 ( this sets it to key 4 - it flashes twice )

24. Hold the magic button until it flashes twice.
25. Press 994
26. Press Magic Key (don't hold)
27. Press 00079
28. Press 5 ( this sets it to key 5 - it flashes twice )

The remote is now programmed and ready to use, to make the BDV-E370 region free:

1. Use the remote that came with the player to bring the player out of standby, make sure there isn't a disc in it.
2. Press 1, 2, 3, 4, 5 on the oneforall remote. The 24p light will start flashing. (Centre light)
3. Put the player back into standby with the Sony remote.
4. Hard reboot machine (remove power)to prevent the 24p light flashing indefinitely.
5. Next time you turn on the player it will be region free for DVD playback.

This worked for me, but obviously I accept no liability for anyone who tries it on their machine.

My Panasonic SC-HT995W keeps on flashing W and the rear speakers wont work. Ive tried turning off all other wireless devices but it still persists

I had exactly the same problem. My unit worked fine until a loose power cable resulted in the receiver being turned on and off a couple of times in quick succession and then after this the a/c in light on the rear speaker was lit but the wireless link light would not come on (and the 'W' on the main unit flashed constantly). The solution for me was basically a reboot. This is what I did;
- unplug the wireless receiver
- unplug the main unit
- remove the digital transceiver unit from its slot in the back of the main unit
- plug the main unit back in and turn it on - the 'W' won't flash as the transceiver has been removed (not sure if you if it's necessary but I made sure it was producing sound to the front speakers)
- unplug the main unit again
- reinsert the digital transceiver
- plug the main unit back in, turn it on and set it to produce output/sound (the 'W' will be flashing)
- then plug the wireless receiver back in again
...presto the link is made, the 'W' stops flashing and the rear speakers work again.

Hope this elaborate reboot works as well for you as it did for me.

When i push power light jus flashes and nothin powers up

there is a single capacitor on the main power board that has burned out. I found another site that had a great step by step with pics but now cant find the link...if you take the unit apart and look at the board where the power cord is your finger across the top of the black and silver capacitors you will find one that is slightly buldging up...that is your problem child...a new one cost a whole $1.62 at cost me 3 bucks for the solder since I couldn't find took about 35 minutes to repair...the hardest part is flipping the board over and melting the correct solder point around and see if you can find the web site I mentioned he did a great job of explaining it...his fix was for a slightly newer model but it was spot on...good luck

My power light keeps flashing.

Diagnostically this isn't a signal that the company lists. This therefore must be a short. Bring this in for service and let them know that your device wont power up. I'd say it need a nes switch or power supply. Hope this helps! Thanks!
