Hi.

I may be able to help you but I need to know the chassis number of your tv set.
This will be on the back of the set on the same label as the model number or if not there it will be on the main pcb.
It could start with AK, or PT.

SOURCE: Normal Picture Mode Not Available With Cox HD-DVR (Motorola DCH3416) and HDMI Cable

With an HDMI cable connected, the cable box determines the picture size. The settings on the cable box must be changed in order for you to get the correct picture size. I have some experience with Motorola cable boxes; usually to access the settings you turn the box OFF and then press the menu or settings button on the box to bring up the display menu. Hope this helps!

SOURCE: Phillips PC7225 Menu

Found it!
I have a Philips universal remote. After trying half of the codes for Philips TVs, I came up with one which allowed access to the SETUP menu. It was 0621. This allowed me to run the auto channel setup, as well as fix some of the other functions. I don't know if this works with all remotes, but if you try different codes, you should get lucky. I'm sure it helps if you have a SETUP button on your remote.

SOURCE: Mitsubishi TV had horizontal lines across the screen and rolls up

Answer
ONE: Yes, the speaker mounted close/near to the set can be a cause of mischief; please move it further away and see if that helps clear up the problem. But, you must keep it away for several days before you will know for sure because it takes some time to degauss all the internal parts that may have become corrupted by the magnets in the speaker.

TWO: Yes, any set can be repaired the question is cost and wisdom. Old sets are sometimes not worthy of the repair simply because of the likelyhood that another failure will follow soon after. A big screen always invokes a repair charge of $200 and up. After a few of these you will wish you had put all the money into a new set!

THREE: The lines are most likely a problem in the vertical blanking circuits of the set. These are horizontal retrace lines that are supposed to be blanked out during vertical retrace of the raster. Think of it as a paintbrush that scans across the screen painting thin lines and when you get to the bottom of the screen it goes quickly back to the top, but during that time the horizontal, which is many times faster, has made several sweeps; so it must be blanked out during the retrace. The repair involves finding the guilty parts and replacing them. Usually this repair runs over the $200 somewhat.

FOUR: Prior to calling in a service tech try a hard reset to see if that will recover any of the circuit degradations. Merely unplug the power cord and leave unplugged for 4 hours or more. It may help. Or, it may not help; but worth a try since is won't cost you anything.

If the set is over 5 or 6 years of age it probably is not a condidate for any expensive repair. On the other hand, it is a Toshiba - and they make a fine set.

Hope this helps. Let me know if you have further thoughts.

Can I connect the usb port on the DVR-625 to a TV with a usb connection and get a better picture? ?


Hi Roy Yoerger!

You would not be able to use the USB connection on your receiver to get a better picture. To get the best picture on our Standard Definition receivers, I would recommend using Component (RCA) cables.

How to record to vcr player/recorde from dish 625 dvr


Hi, Mari!

You can definitely use a VCR with your DISH 625 receiver. To set this up you would need to connect your VCR between your receiver and the TV.

The easiest way would be to run RCA cables from the TV Out to the VCR's TV input. From there, all you would have to do is run cables from the VCR's Out to the TV. Make sure the VCR and receiver are powered on and change to the input on the TV based on where the cables are plugged in on the TV.

If you have any questions let me know!

Do you really have TV Audio OUT to a DVD (last sentence)?

Most DVR's have digital and analog audio outputs. Since every device they are intended to feed would have its own volume control a DVR output volume control might be redundant. Treat a DVR like any other audio device. Connect it to any available input on the receiver EXCEPT PHONO.

If you run the audio from the DVR (and EVERY video source) directly to the STA-795 you can bypass the TV and its questionable audio electronics (yuk). You can split the analog output of the DVR with y-cables and run it from the DVR to TO the TV for casual viewing and listening through the TV sound system (news, Oprah, etc).

Trouble using Motorola DCH6416 HD DVR with standard def. tv


I fixed the problem! I found a posting on a message board by someone who had the same DVR and a similar problem. This person found a way to access a secret menu in the DVR to override the format which is automatically assigned. I followed the same steps to access the menu on my DVR and then tried changing a few settings until I found the ones that worked--changing the automatic setting from OVERRIDE to STRETCH and changing the output setting from 1080i to 480p. (It's pretty pathetic that no one at Charter could fix this problem!) Here is the link to the posting that I used: http://www.avsforum.com/avs-vb/showthread.php?t=1132766

Vertical rolling on Hitachi 60SBX78B


It ended up being the Verizon Fios box. We recycled it and the picture stopped rolling. Thank you for being here to help. If I have any future questions, I'll definitely use your site.

White horizontal lines at top of picture


Yes, definitely worth fixing. The problem lies in the vertical deflection voltage-doubler circuit. The usual fault is a single capacitor of 100uF/35V that has failed. It is normally connected to a rectifier diode right at the vertical IC. Replacing the capacitor (no more than USD4.00 in price) usually gets it working perfectly again. If you are finicky around technical work, then a reputable local repair shop in your locality should do it quickly for you and charge only labour.
