DRC8335 info regarding VCR board components DU83 and RU83

EERepair. In addition to the usual #C226 capacitor failure, I furtheridentified two other PS caps running excessively hot, which I'vereplaced. Specifically caps #C216 and #C218 both of which are 1000µf.The former having a 16 volt rating and latter 10 volt, as installed atthe factory. After upgrading both to a 35 working-voltage ratingthey're no longer even noticably warm.

Beyond the faultypower-supply capacitors I further discovered zener diode #DU83 on theVCR PCB was red hot, just as in your case! For this reason, I'vetemporarily taken it out-of-circuit so it won't load-down thepower-supply, until it's been replaced.

At this moment, I'm notsure yet myself what DU83's voltage rating is. It's so tiny in size youcouldn't possibly read any of its identification markings (assumingthere are any) without the aid of a powerful magnifying glass! Ichecked all the Service Manual sites, but none have one for theDRC8335. So I'll proceed by using my DMM to measure the source DCvoltage on it's pads and let you know, once I've determined what DU83'scorrect value should be.

Unlike your situation, my VCR board'sRU83 (51ohm 1/2 watt 5% tolerance) resistor didn't fry and appears tobe in good shape. So I'm able to provide 1/2 of what you asked andneeded to know. Hopefully I'll have DU83's value determined in anotherday or so, once I have more time to resolve the question.

Questions:
Have you discovered any further information regarding DU83 since your August 14th post?
Other than DU83 and RU83, were there any other damaged components on the VCR PCB which had to be replaced?

I'mhoping once I've determined DU83's value and solder-in a replacement,this much alone will completely restore the VCR deck functionality. Butobviously there could be further components involved, as a consequenceof DU83's thermal-runaway breakdown.

I noticed one of thetransistors immediately below DU83 felt suspiciously warm, if notbordering on hot. But it was literally laying on top of the overheatingDU83. Once I repositioned the transistor away, it seemed to cool downquite considerably. Obviously I won't be able to make any furtherdeterminations until I've first replaced DU83.

Please email me directly if so inclined and you have time. It'd be the quickest way to contact me. mikeadams110@yahoo.com

My curtis DRC8335 IS STUCK ON HELLO - WHAT SHOULD i DO - I TRIED SWITCHING IT OFF - SWITCHED IT ON - STILL STUCK ON HELLO


There's a blown capacitor in your machine (when you open it up, the capacitors are the little things that look like pop cans). If you are good with a soldering iron (or know somebody who is), they should be able to replace the blown capacitor with a minimum of fuss. I believe the board location is C226.

Hello only on screen


On the power supply board I replaced CAP C226 as per another poster and the problem is solved. It is a 470 uF, 35 VDC capacitor. Bought one at Radio Shack for <$1.50 USD. Radio Shack part number is: 272.1030.

RCA dvd/vhs DRC8335 stuck on HELLO


December 27, 2008 received by email from Ann M.
Just like John H, my problem was also capacitor C226, but in my case overheating wasn't the give-away here. Instead, I noticed the bottom of the capacitor appeared melted a little and the top looked like it was slightly bulged. I removed the damaged capacitor and replaced it with a new one rated at 35 volts and now my DRC8335 is working perfectly again!


It worked it cost me 4 hours on hold with the Republic of the Philippines. Being told the new Unit sent had a 90 day warranty. It did they were right after 90 days it stopped working. The part was a Radio Shack 272-1030.

Just says hello


Capacitors in the power supply are prone to failure on this model. Try replacing C216, C218, C219, C226, and C228 with 35 volt caps available through your local electronics supplier.

This is a simple, inexpensive, repair costing less than $10...
Good Luck

Thanks to the help on this forum, I was able to fix my DRC8335 power supply. C226 was the problem, went to Radio Shack and found the 470uf 35V replacement. It came up and worked like a charm after soldering it in. (See the picture of the cap on the board). It was just slightly swollen when viewed from the top but when i removed it, the bottom was really distorted. Thanks to micro065 and Mike Powellebbca66.jpg

Resister burnt


Guest and Lesfix. RU83 located on the DRC8335 VCR PCB is a 51ohm 1/4 watt 5% tolerence resistor, color coded green-brown-black-gold. As to zener diode DU83, I haven't been able to determine it's value yet but am working on the problem.

Be aware when either or both these components fry, this indicates you need to replace the following two overheating capacitors on the power-supply board, which were directly resonsibile for knocking them out:

• C216 1000µf 16 volt (upgrade to 35 volts)
• C218 1000µf 10 volt (upgrade to 35 volts)

Could you email me regarding this problem when you have time. Mention Fixya and DU83 in the subject line so I realize it's from you. Thanks. mikeadams110@yahoo.com
