Hitachi Plasma Color Problem AVC 75 Receiver Issue

It's a 42" Hitachi Plasma using an AVC 75 receiver manufactured in 05. When cool, the picture is perfect. After about 90 minutes or so the unit heats up enough to start changing / flashing colors (red tint, green tint, Blue tint, B&W. This continues for about 30 minutes and then numbers appear, over the picture, that go from the top to the bottom on the left side of the screen. It almost looks like a count down timer. It'll also start changing the picture display (zoom in) narrow screen, completely black, etc. I pulled apart the TV and cleaned all the boards (it was pretty nasty), checked for cracked solder joints, obvious diode or capacitor failure, and everything looked great.

If I isolate the receiver unit, and put a fan on it, it runs perfectly for 12+ hours. Once it gets going nuts on me, I can turn on a fan and it'll take about 30 minutes to get it cooled down enough for a normal picture. After getting it all dusted out (the internal fan was pretty nasty but working), the performance got better but still has issues. Everything inside it is pretty clean now, no obvious component failures, heat syncs seem to be intact, fan is working, and when cool, it works great. Any ideas?

SOURCE: all color guns out of alignment

Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.

SOURCE: HITACHI 53SBX59B, projection lights don't line up.

It sounds like bad solder connections in the convergence output circuit. It may also be an intermittant convergence output ic which will need to be replaced.

I have dish network and am trying to watch tv on my gateway plasma. how do i connect my satelite cable to plasma to get picture?

We would like to guide you through the connection process,but depending on what kind of receiver and TV you have this process may vary.Visit our "How to connect receiver" page here:

Once we have everything connected correctly, check what channel or input yourTV is currently on by powering the TV off then back on and noting the channelor input that appears on screen when the TV is powered on.

Steps for getting picture on TV1:
If you are using a Coax Cable to connect the receiver to TV1, check thereceiver's back panel for the output name. If your receiver has a "TVCH 3/4 out" (non-ViP Receiver): Tune TV to channel 3 or channel4, if it has "Home Distribution" output (ViP Receiver):Tune TV to channel 62 or 75. If using non-Coax (RCA,Component, or HDMI) to connect receiver to TV1, cycle through the inputs untilpicture appears (this information may appear on the remote sticker), mostTVs have a "TV/Video", "Input", or "Source" button.

Steps for getting picture on TV2:
Access "Modulator Setup" from TV1 by pressing "menu"then 6-1-5. Tune TV2 to the channel that appears under "TV2 Out" onscreen. If still no picture, change the "TV2 Out" mode fromAir to Cable, or if it's already on Cable, change it to Air. Then change thechannel of TV2 to what is now displayed under "TV2 Out".
If the issue is only on ONE receiver, unplug the DISH receiver for10 seconds and plug back in. It may take up to 5 minutes for the reset processto be completed. If you still are not getting a picture, connect anothercomponent (VCR, DVD Player, etc.) to the same TV, using same cable, same input,and same channel to see if it works. If it works give us a call at1-800-333-DISH (3474) for additional troubleshooting, if you don't get apicture with the other component, replace the cable.

Hope this steps help, and thank you for being a valued DISH Network customer!

Hitachi 42' plasma - even when I adjust aspect ratio, the edges of the picture are still hidden, as if it is zoomed in to much. Is there a way to resize the picture?

I don't know if this will help. If your using a cable box or satellite receiver they also have format buttons that can adjust picture size. Maybe you could try to adjust them.

Receiver is powered, monitor is not

You probably have a broken TV if it's still under warranty you should call the manufacturer.
