Toasted my DV-981HD today! It spit out the DVD I was playing with full speed. Then after rebooting the screen says PO (letters missing) and power light is same time red AND blue(ish). The player was pretty warm over Power Supply Unit (left side) and I opened it up and it looks like 400V47uF (TC501) capacitor has melted at bottom. Also some temperature marks on circuit board.

 

 

This is the second Oppo DV-981HD for me. First one went to warranty and I got back another with no cost. First one worked under one year with average use of 3-4hrs / week. This second lasted about 3 years.

If you send it to OPPO for $50 you get a rebuilt unit. I did and they sent it back in a week. The display and power supply were fried as weell as he qptical drive so all got rplaced with a 90 day warranty.

Yes, got mail from Oppo. $49 for repair service + postage. Most likely there is more damage than just a PSU circuit board. But I happen to live in a country that has high postage fees (over $60 just for sending the unit to Oppo) so it's not worth of repairing for me. I can get a new Blu-ray player ~ $100.

 

Thank's to Oppo's customer service (answers came almost immediately). Sadly there is clearly design flaw or bad components in this product.

Worth repairing OPPO DV-981HD for $89 plus shipping?

The OPPO DV-981HD I purchased in 2007 just went on the blink. It got great reviews back then during the HD/Blu-Ray wars & it has worked fine for me. It now has the purple/pink light of death on, which, per this forum seems to be mean the power source has fried. I emailed OPPO and they said they would repair it for $89 plus shipping (a bit more than the $49 mentioned in the older posts). Not sure if it is worth doing. I don't have any Blu-Ray disks nor a 3D/4D TV. Mostly use this for playing CDs and upscaling to 1081P my legacy DVDs. I use my Tivo Roamio to stream movies. I like that the OPPO unit has a display & I don't really need any of latest features. But for about the same price, I could buy an inexpensive Sony or Samsung. Worth fixing? Opinions appreciated. Thanks.

Welcome to AVSForum.

Doesn't Sony use Mediatek in their players? Same as OPPO uses for Source Direct and pre-video processing. They have really upped their game in recent years and I suspect will give better DVD images than the Faroudja processor from the 981 era. (I think the 981 had that....)

I did mine and total with shipping was $80 CAD but I have a lot of DVD-Audio disks. If you don't need it for that, then no I wouldn't do it. I think mine was caused by putting a bad firmware on it. Do you know what caused your unit to fry?

You might want to try replacing the cap yourself. I did one on a motherboard that was fried a few years ago and it worked after.

Here is what my Oppo info screen looks like. It stopped working. I blew the unit out, which seemed to help, but something IS amiss! Can I get some firmware? The linkI hit a few posts back is no longer good...

Heads up for DV-981HD owners that Oppo is no longer fixing these. They are out of the front panel repair part and have decided not to offer the repair any longer. If you have a working Oppo that was not refurbished by them, I would strongly advise that you recap the power supply now before it goes bad and ruins the front panel. I have an original and refurbished PS from Oppo and will post some info shortly regarding the repairs they made. Some cap sizes were changed from the original, as well as one power resistor value. I have been unable to find the ET16310 chip on the panel which might be the culprit (it is possible that the leds themselves are bad, Oppo was not forthcoming on this info, just said the panel goes bad). If the panel is already malfunctioning (displaying odd characters), then repairing the PS will not bring the unit back. I replaced the PS on a bad unit with the Oppo rebuilt power supply and the unit would not turn on. All lights on the panel lit up blue, but no power on was possible.

Oppo DV-981HD

So its a power supply issue. Mine went out just after a firmware update and I thought it was that. Oppo repaired it beautifully but I fear that FW update will fry it again. Am I out in left field.

P.S. I love your handle LukieDog:)

Well, that explains why when I contacted them yesterday about this same issue the e-mail reply said it could not be repaired. That confused me because I had remembered others having this issue, but you just confirmed that it used to be something repaired, but no longer. Oh well...

Oppo DV-981HD Fix

I am posting pictures of a stock and “repaired” power supply board for the DV-981HD. The caps you see with gold stripes are the ones Oppo replaced (they did not replace them all). These are now “low esr” capacitors. All caps are 105oF. Most importantly, the power supply gets hot when the unit is sitting unused. I would suggest unplugging the unit when not in use or installing a switch at the outlet to easily turn the power off to the unit. Heat is a killer and it is this heat that is probably the main reason why these units are failing.

Stock Revised
TC505 1000uF/10V 1000uF/10V
TC506 1000uF/10V 1000uF/10V
TC509 1000uF/10V 1000uF/10V
TC510 1000uF/10V 1000uF/10V
TC512 47uF/50V 100uF/50V
TC511 100uF/16V 100uF/50V
TC513 100uF/16V 100uF/16V
R511 220 ohm Dale RS-1A 400 ohm

Basically, caps were replaced in kind with “low esr” type, except TC512 and R511, whose values were changed to what is shown on the table.

I would suggest just going ahead and changing the few other caps on the board, why not? Just a few bucks. Low esr are fine.

TC503 470uF/25V
TC504 470uF/25V
TC508 100uF/16V

Use good quality “low esr” and “high reliability” capacitors from respectable manufacturers. If you had Oppo repair your unit, they used “Acon” capacitors, probably crap, might as well do the right thing and replace with name brand capacitors. The Dale resistor is fine, though. If you are not up to it, then just ensure that you make sure unit is unplugged when not in use.

If your unit is experiencing strange characters on the display, I am sorry to report that the unit is toast and will not benefit from this repair. This repair (and unplugging the unit when not in use) is to ensure the unit does not go bad. If your unit is working properly, proceed with this repair immediately before the unit dies. The reason this is so, is that the failed power supply destroys the display chip ET16310. This IC is mounted behind the front panel. Once destroyed, repairing the power supply will be futile, the unit will not work with ET16130 fried.

If a unit appears on eBay quite cheap with issues, forget about buying it and thinking the power supply repair will work, it will not. I am keeping my eyes open for ET16310 chips to effect a repair, but these may no longer be available and it is why Oppo will tell you they can no longer fix this unit. With a Quickchip repair kit, this IC might be able to be replaced. But you will need to get ahold of one, and at present, this appears to not be an option.

So if your unit is working, replace all caps and resistor as directed and keep that unit off while not in use.

Ah, so if the unit is already at the purple power LED stage with a bad power supply then ET16130 is already fried and no point in replacing the capacitors?

I installed a known good power supply into a unit with a bad display panel and it did not fix the problem. Once the display is gone, the unit is dead beyond repair until a replacement chip becomes available. Best thing to do if you have a working unit is to plug into a power strip and use that to cut the power on and off. I believe the unit cooks itself dead while in idle, you can feel the heat on the case in the front left side.

OPpo is repairing them again. Sending mine in
Really? For the purple power-on LED issue? They told me via e-mail before they would not. So did you send a new e-mail and get authorization to send it in?

mewisemagic Did you get your DV-981HD back from Oppo repair yet? Was this the power-on problem (where the LED stays purple) that they had said they would not repair?
