No picture The VCR is playing but I cannot get it to show on the TV monitor--no picture, sound, etc. It was working fine, but then stopped working. I checked the power and the connection between the vcr and screen, but these are fine.

It sounds like you may have your vcr connected via composite cable. Check the back of your VCR and follow the cable to your TV. You should see a Red, White and Yellow connection on both ends. The Yellow connector is the video.

Here is an image to help you find it:

The TV channel should be set on Chanel 3 or Chanel 4.
Use the remote control of the TV to set it.
You can also use the AUX ports (to TV) on the VCR and connect the three wires to the AUX ports on the TV (TV input). The two audio wires are to be connected to Audio in and the Video signal to the Video input.
If you get a garbled picture you can use press the tracking button on the VCR. Usually you press the Channel Up arrow, or Channel Down arrow to adjust the picture.

Possibly dirty video heads. I would suggest that you run a head-cleaning tape through the VCR deck to shift surface dirt off the heads. If that doesn't work, or it sort of works, but not satisfactorily, unplug unit, carefully remove top cover, and with the VCR deck in view, gently clean the heads with a soft cloth or special cleaning stick (these look like flat q-tips but are intended for VCRs - available from electronics/hobby stores) and some alcohol (methylated spirit will work if that's all you got - but isopropyl alcohol is recommended - available from the same places as the sticks) clean the guides (gently so as not to disturb their alignment) clean the pinch roller/capstan shaft - CTL (on the right-hand side of the drum) and FE (left side) heads as well. The whole tape path should be carefully cleaned. Refit top cover (carefully), plug unit back into power, wait until it completes its startup/loading procedure, then put a tape in. You should now have a playback picture with the sound. You only need to do this as required if head-cleaning cassettes don't work properly.

If none of the above cures your problem, then the heads are abraded/worn - let's hope that isn't the case here. This model does not use a built-in head cleaner.

use a cleaning tape. you lost me sorry

u have to run it directto tv yellow cable ok and sound cables not throw dsh tv

If you have pets check your cables and make sure they haven't been chewed on or pulled out or even loose.

Don't pass the video sample through the Onkio.. Use a second single RCA patch cord to go from vcr to TV... Use the same yellow out on the vcr that you're using now and send it directly to the yellow video input you're using on the TV..
Hope that's clear - I'm getting tired...

What you state cannot be logical. If picture is freezing, then the VCR is at fault. But you state that the VCR works fine when played, and viewed on another TV. So, the only explanation I can think of is that there is some thing faulty with your VCR. Probably, when you play a tape, the picture freezes. This could be 'cos the Capstan motor of the VCR freezes. Common problem with aged VCRs. Just requires a spot of grease, and service. IT CANNOT BE THE TV AT FAULT!!!!

Your unit has it seems to have developed a video problem. it could be in the video switching IC or the video processor. Its going to need a trained technician, who knows how to use an ocilliscope to find the video problem.. Good Luck
