Proscan 32... When I trun on the TV the light does switchs from one color to another like the TV is on....but the picture doesn't come like the TV was never turned on...I have to unplug and plug it back in at least 20 or 30 times hitting the power button... Then if I am lucky the pic will come out...what do I...?

The TCON board or the LCD panel is faulty. Can confirm by replacing the TCON board.

If the TV has an unused HDMI port, use the HDMI cable that comes with the WII . If not , then use the 5 cable Hi def cable . Match the colors RGB on the cables to the same color input jacks on the TV The red and white cables are the audio. Make sure you don't get the wrong red cable mixed up. Note the input number near the jacks you use on the back of the TV. Select that number with the input button on the remote to see the picture.

Just do a hard reset to this set and check. To make it a hard reset, unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If this do not help you, the main board to your TV is faulty. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

Try resetting it to factory settings and see what the color looks like.

Check to make sure the Video connector (YELLOW) is connected to a YELLOW plug on both the TV and the DVD. If it is plugged into a GREEN plug then it will produce the black and white picture and not a color picture.

Good Luck...

your toshiba player should have output composite video and audio which are color coded Yellow for video, red and white for audio same goes for proscan hdtv. connect between the two keeping in mind color of cables. If the toshiba player is really old you can connect the RF cable output to antenna input to the proscan tv and watch taped programs from the player on channel 3 of the proscan tv. If then you want to keep the hookup and still watch HDTV connect the antenna to the toshiba vcr and when you shut off the vcr you can now watch the hdtv channels as usual because now you are bypassing the antenna to the Proscan tv. Hope this Helps..

Can you tell me how to connect my dvd player to my 42 inch proscan hdtv ? There are no yellow,its blue and there are two rows of the same colors.

look for horizontal control

It could be the start of a high voltage leak. A bad anode cap on the red wire going to the picture tub. try putting a little silicone sealer around it and hope the transformer is not the one leaking.
