Philips Magnavox VRA670AT21 VCR tries to spin belt, then shuts down

My Philips Magnavox VRA670AT21 was working fine, and once when I tried to put a tape in, the loading mechanism went down without the tape in it. Now it won't eject, and whenever I plug it in the loading motor spins but the belt does not move. It shuts down after a few seconds of that. I cleaned the belt but it didn't change it. What should I do? Thank you for any help.

Buy a different one, it's going to cost more to fix than one can be purchased for at a rummage sale

    hi larry i can't find how to contact you but i need help with my 75Q8G hisense , i changed the powerboard , hisense sended me a USB to try reset the tv with fresh install , and nothing work , i even changed the cable , she stopped working after we loss electricity a night and she was on , this tv was used less than 30 hours and im so lost rn , i tried EVERY trick on the internet , and the white led still blink , she blink one time and pause 1 second , maybe it's a kind of code ? a LED is dead ? thank you

    Hi Jason, is your TV still under warranty? If so return it . The reason your not finding much info on the set is Hisense doesn't have the best customer service or that's what we have found. As long as the standby light is flashing you have standby voltage, next thing to test would be the voltage that tells the power board to come out of sleeping mode and turn on so the set can power up, most Hisense sets have it marked PON, you should see around 3 VDC there using frame as ground, if you don't see that voltage the main board has issues, if you get the voltage there the PMW circuitry should be working and the other voltages should be present. I'm going to have you test the power on pin and see if you have voltage there before going any farther

    sadly it's out of warranty of 2 week i asked if i can still have one , and they said no. i changed the powerboard completly already , and the cable ( and power cable ) , i just received the mainboard but i didnt install it yet , the tv didnt get shock or something we just loss electricity and was connected on a powerbar ( i bought a better one with antisurge build in ) and i was tinking is really the mainboard was hit by a simple unexpected powerloss....... ?? are these hisense tv that fragile ?? , and hisense doesnt help much ive been dealing with them since 2 month and they just basicly told me to f*** off.... if i change the mainboard , and the light still blink the issue than will be a backlight strips ??

    There was a chance of a power surge when the electricity went off, but that shouldn't have done anything to the main board, it could have damaged the power supply, but you have already changed that. Where did you buy the replacement board? Hopefully not ebay as it's a toss-up getting a working board or another defective one. Also, backlights shouldn't fail on a set with very low hours, it's possible but not probable. As long as you purchased a main board install it but I would be surprised if it helped, a simple voltage test would have told if it was working or not in the situation you have, the one I described in the last message.

    i bought the board from CCSI – IT Products, Services & Solutions , good rating and i double checked and ppl bought hisense part from them and work great , is the backlight and burn if the tv close with a electricity loss ? , or the controller backlight maybe ? , it's weird how just because we loss electricity the tv is done , i double checked with all the reset and fresh install with the USB hisense gived to me , and nope , nothing work , ill change the mainboard tommorow , and if this blinking led still happend , the issue is maybe from a dead LED that didnt like to close to fast... ??

  • Larry Jun 19, 2022

    No sure what you mean by "dead LED that didnt like to close to fast". I'm not familiar with CCSI but most companies that sell parts are ok, it's the fly by nighters on ebay that get sets that don't work and pull the boards out and sell them that aren't reputable. The backlight inverter is part of the main board, you replaced that so that should rule that out. If the main doesn't fix it, it will be time for some actual trouble shooting to find where the issue is at. Backlights shouldn't have failed from a power failure but with electronics anything is possible, over the last 40 years that I've been working on all types of electronics I've learned not to rule anything out

    update i changed the mainboard and everything work , doesn't make sense , how can these mainboard are THAT FRAGILE ??? next time we gonna loss electricity this issue can happend again , or should i buy a APC backup ??

  • Larry Jun 20, 2022

    There is more sensitive electronics in the main than the power board but usually the main is more protected as it's not directly tied to parts that get hit. Glad you got it fixed

Magnavox VCR/CD player will not come on. It is

I have purchased a new VCR/CD player. I tried everything, but nothing worked. I did purchase another Magnavox, but if this machine does not perform any longer than the first one, I will not purchase another one. The reason I purchased a Magnavox this time was that there were no other products available in my town.

T.V. shuts off when I try to play a DVD in the built-in player

Try putting in a VCR tape let it load and hit stop. If the set stays on it's the VCR deck causing the problem. It will be either be bad sensors or LED or possibly the mode switch. Let me know if this helps.

Philips Magnavox DV200MW8

The tape player section has some safety sensors inside that will shutdown the system when there is a problem. The most common cause of this is either a bad belt or "idler". If the tape is not moving or the take up side is not moving, this will happen. This is a simple repair for any shop and should runfrom $5-$25 for parts (belt - idler) plus the local labor rate.

Magnavox combo vcr dvd

What you're describing is common when the center LED has failed / gone out. If you're really good at taking a unit like this apart and putting it back together - and not too bad with a solder stick you could attempt this one yourself... It is a pretty intensive repair but not difficult for a good shop just time consuming. The part isn't too expensive either, just an infared LED... In fact, we've run a bit short on stock once in awhile and bought one of the off the shelf versions from Radio Shack which worked just fine. Good Luck Bill
