SOURCE: my jvc lcd shutt down every time and i dont know the rason

I can honestly say I have been quite happy with it and its performed pretty well with very few problems and is still going today.

First of all congratulations on getting so many years of heavy use (2002 - 2012) on your JVC VCR.

I have a HR-S3911U and a HR-S5912U from the same era and my 3911 has seen a million miles and both my units are still going strong. I did experience a similar problem with my HR-S3911U but instead of the eject function my problem was with a sticking guide-pin. I did a have similar ejection problem with one of my 1985 Super Beta Hi Fi machines. Really it sounds like the exact problem as you describe. What I did was I opened up the unit and watched carefully - it was just a sticking moving part. My JVC guide-pin problem was just sticking as well - after a gentle push into place the guide pin has not stuck since. I don't suggest using any grease unless you really have to. I suggest you open the unit - if you have a video camera video tape the ejecting and play back in slow mo to see if you can catch the problem. Sounds like a sticking moving part which can be common on any VCR.

..couple times its had issues with dirty heads as i would get a message appear on screen.

I'm very surprised that in the past you had "dirty heads" messages pop up on screen as I have never seen that message on my JVC machines and I do use them a lot and very rarely clean the heads. Proper tape storage is very important. Trying not to use the same tape over and over again also helps keeping the tape path reasonably clean.

I think it could benefit from the heads being cleaned. I don't even really know what are the heads. Is it that big round drum? One thing I did notice is that when I load a tape, it straight away wraps the tape around that drum and the drum spins away and just idles there constantly rubbing on the tape before i have even pressed play. I have left tapes in there for days and days, so I assume this cant be good having that thing spinning away on the tape for such a long time?. I am not sure if this is normal or not but I wont be leaving tapes inserted in the VCR long periods now.

The heads are tiny little things inside the big round drum. I will show you if you post a picture of your unit with the cover off.

The tape staying wrapped around the drum with the drum spinning is normal but the drum should stop spinning five minutes after you load the tape as long as you don't touch play, rec ,ff or rewind. This is called a "long pause" (the tention is a little eased and is not rubbing hard as a normal pause would) and the long pause is there so the unit will immediately start playing or recording if you push play or rec within 5 minutes of loading the tape. If the drum does not stop after 5 minutes of sitting idle then your VCR has a malfunction and you should not leave tapes in the machine idling.

I am concerned about your heads clogging up - that is not normal unless you don't take proper care of your tapes - is there very high humidity in your area? That could cause problems.

Sorry I posted this in a hurry but will go into more detail later if need be.

Se50fy10 backlight not working


This is an exact problem that I am facing with my Seiki 50" TV. From my research, here are the probable issues:
1. Main Board/T-Con Boards are fine
2. Power Board : MIP550D-5TB could be defective - most probably the culprit. There is a power test to try but w/o schematics, it is not possible to identify component
3. If Power Board replacement does not solve, it is the backlight LED strips that are defective - tought one to replace.
Will update this thread at a later date.

Our Haier 42HP25BAT Plasma TV made a loud pop sound and the picture went out but it has sound...will the replacement of the TV-5210-96 Digital Board solve the problem?


The TV need a thorugh check up, before doing any repair to it. Some repair works, can be done manually. It sounds that some electrolytic capacitor on the main power reguaator board has bursted out. Check the power regulator baord first. Digital baord faults are rare. In most cases, main power board might be replaced as card basis.
