Toshiba - colorstream HD - no picture or sound

Why can't I get a picture or sound? picture froze in the middle of watching. after turning off I turned back on, and there is no picture or sound, colorstream is showing 3 plugs down, how do I get the picture and sound to come back. No one has touched the back, so nothing should have come out?

SOURCE: toshiba colorstream 27A33 TV

1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.

SOURCE: Power problems problem on

I would try a power drain:  Unplug the TV's power cable so the TV is not grounded to the house.  Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens.  If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.

I have a 65 inch toshiba cinema series it's says


if a large rear projection set that just says HD, it likely is HD ready which means it needs a set top box connected to the Colorstream input marked 1080 on the rear of the set--It will only likely be 1080i and not p---owner manual would confirm this.

I would suggest to leave your directtv hd/dvr box connected the way It is.
The HD Colorstream 1input on your TV should work just fine.
This TV does not have an HDMI input but you can buy an adapter and connect to DVI/HDCP IN and that might be able to get 1080i video resolution on your TV.

Toshiba CN36X81 television.. NO Sound... Great Picture. Using the TV2 output of a DISH Network HD receiver... TV2 output is std def, coax output. Using a different TV I get picture and sound... but not...


IF coming in via, the "Dish" networked receiver, please check that this volume is turned way up, on the TV. and then control the the Volume, with the Dish Remote, often this is a problem, as one is turned down, and the other cannot turn that up, simply try syncing the Volume controls, UP on TV, control the Audio with dish remote. thats all i can think of. Check by feeding a signal IN from an AV, source, ie: Yellow, Video, & Red& White, Audio. Turn TV UP and check, IF it responds to this all is well. If NOT then you do indeed have a fault, with the TV.

If you have the wires switched GEEN,BLUE,RED on one end the color will be wrong. Check that the color off the wires are matched. Try a new cable. I've seen this a lot.

There should be a wide/screen size/ format button on the TV remote that allows you to make those adjustments.

No picture, no sound, but has power light...any suggestions? thx in advance


Do this first:


1: Check the antenna/cable connections.

2: Press the TV/VIDEO on the remote control or the TV to view a signal coming from another device connected to your TV, such as a VCR or
video disc player. You can select ANT 1,
VIDEO 1, VIDEO 2, VIDEO 3, ColorStream HD1, ColorStream HD2, or ANT 2 depending on which input jacks are used for connecting the devices.

*Be sure you have the right source to view video.

Try the above and post back before I can say there is a problem with your unit. If you have the user manual it's a good time to get it out. If you don't have it let me know and I will give you a link to obtain it. Good luck!!
