Re: video/dvd

A voltmeter and/or oscilliscope can tell you if the p/s is dead. If the +5 volt line is dead, the VCR will certainly be dead also. A visual inspection of the power supply section might find bulged electrolytic capacitors, and immediately give diagnosis.

You might succeed with repairs by just replacing these parts in the p/s. Capacitors are low cost- often less than $2.00 each. I use the Panasonic FC series available from Digi-Key for supply lines, and NHG or two in certain other areas.

A schematic would be helpful as Wolf states, but not always necessary in a dead power supply repair.

Re: video/dvd

You have to do is find a schematic for the power supply and replace every capacitor in it. Particularly the starting cap. this is tedious awful work and with the replacement value so low, but ok that's it.

Our Hitachi MX818E VCR is suddenly not playing videos. We can hear the sound however. We do not have the user manual anymore. Thank you, Ann

a common problem is rental videos that have been damaged in the first few feet of the tape by some other vcr's defective drive mechanism that "eats"the tape..What happens is the particles of the damaged tape clog the video heads in your machine,which have gaps in the millionths of an inch.Put a brand new tape in the machine and let it play for a half hour or so and it will usually clear itself.If that does not do it,insert a head clening tape and a couple drops of cleaning fluid and run it through.The newer machines will show a blue screen if there is no video information present.However,if you put it on forward search,it overrides that feature and you will see a snowy picture from a good tape,if one video head is clogged and the other is working.There are 2 video heads on a rotating spins at 1800rpm and that is the whirring sound you hear when play is pressed.If both heads are clogged,you will see a snowy screen and no picture at all.A 4 head machine has 2 heads for slp or 2 hour speed and the other 2 heads are used for lp and slp.A hifi vcr has 2 more heads,which are used for the hifi audio,a total of 6 heads.The stationary playback head has a control signal for tape speed,and regular audio,mono or stereo.

Videotape dubbing deck dead


1. Check to see if a tape is jammed inside (see 284 Extract a Jammed Videotape).
2. Try changing the video input and/or output source. Many VCRs have two ways to receive and send a video signal (coaxial and video direct). If that works, try changing the cable for the other method to see whether you need a new cable.
3. Clean tape heads (see How to Clean VCR Heads).
4. Open VCR and inspect any belts that are accessible (see 284 Extract a Jammed Videotape). A drive belt may be broken or loose.

If tapes are getting stuck / enmeshed inside the machine, itis 90% probability) a mechanical problem. Change the Belts, clean all rollers, idlers, and braking pads.
I would suggest that you also replace the Capstan Pinch Roller.

One vcr is about 2yrs old the other almost new one is a magnavox the other a philips they are both eating tapes not evetytime but alot of the time.I want to copy my tapes onto dvd but afraid I will ruin...

The problem is that both machines may have the same fault, or different faults.
Eating tapes is common and multi faults can cause it. Some of the most common are errors in unloading from around the head. The capstain roller being worn. This often shows in a crinckle cut effect on the tape.
The only way to know is to take the top off and see it doing the damage. You can use a old tape for this purpose.
The most common problem is mode switch failure, this means that the video doesn't know what position it's in, hence the tape damage. However fitting a new one is very hard as the entire mechanism has to be set up right.
You might have a better chance of getting the more recent video repaired as the parts will still be around.
If you have a look at it doing the deed, then describe it here on FixYa, an expert might be able to pin it down for you.

I have a two year old Phillips VR550 video recorder which,up until a week ago,was working fine.Now it wont record & seems as tho' it's not tuned in.We have tried everything.On a pre recorded's...

The most common cause of this symptom is a failure of the capacitors on the head/drum assembly. These caps are involved in the servo-lock circuit. Basically what is happening is that the heads are not spinning at a constant speed. This causes a mis-read of some of the vidio information. This is a simple repair of replacing the 3 caps on the assembly. Please note that these are likely to be surface mounted components and should be replaced by an experienced tech.

I have a Daewoo Twin Tuner hard disc PVR with a firmware

I had one with the same firmware faults - in the end I had to return it as Daewoo had no plans to update the firmware. When I returned it it joined a huge pile of them in Currys.

There is no regional coding for VHS. Its only for DVD's. All you have to do select the correct playback format - PAL/Secam/NTSC
Usually N.American tapes are in the NTSC4.48 format. You could also just set your VCR to "Auto".

Hope that hepls.

VHS tape was playing . After stoping does not play. Other tape will play

The idler wheel (that only drives the tape in play or scan modes) is slipping too much (very common problem). Try verify this by putting the tape in play then immediately press the fast fwd or rewind buttons to scan the tape. On older machines, the idlers used rubber friction tires - on newer ones, a clutch. Either replace the tire or increase the spring tension on the clutch.
Hope Ya Fix It.
