Just bought toshiba 40rv525u. worked fine for 2 days, now picture freezes on all channels. Fine for vcr and gaming theough. Checked cable on other tv's and is fine.

Seriously? You are still using a VCR?

Do you live in an apartment? Could be a neighbors remote interfearing with your TV.

have you connected up correctly, have you selected correct EXTERNAL inputs, you do NOT "tune" a Channel to see picture, you choose external AV input on set. Must connect color to color. 3 for Composite Video AV.Yellow, Video, Red & White Audio. and 5 cables for Component 3 for Video , & 2 for Audio Blue, Green, Red, Also Red & White, Audio.

Try updating the firmware to version 1.05 from this website http://support.toshiba.ca/support/ceg/downloads/all/view.asp?docid=D000020

I got rid of the tv.

Oh man dont shoot your stuff instead use your remote and go to your menu and select your input. You tv is looking at your coaxial input but you can select which input you want. 1, 2 front back whatever you need. channell 3 or 4 has nothing to do with connecting up your dvd if you connect and choose the front connection in your menu.

I have sound on video 2, and when on a static channel but not on the usual channel 3 which is TV. Just stoppen working one day and cant figure it out... Please help!

Make sure you are giving the VCR a signal.
If using a RF source (cable or antenna), make sure the VCR's tuner is set up for the right type and channels.
When trying to record put the TV's input to the VCR to make sure it is getting what you want.

plug your cable connection to a vcr "in" then run a seperate cable cord from the vcr "out" to your television (which should be on channel 3 or 4) depending on your vcr setting and use the vcr to control the channel so when your westinghouse freezes and becomes unresponsive you could still change the channel and so on through your vcr and tv acts like a monitor works for me. N.B be sure to set the volume and so on before it freezes which could be like a 1min window from turning your tv on

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!!!!
