SOURCE: no pic/sound

If you dont here anything then it sounds like the switching power supply or the horizontal output circuits not starting up. this requires troubleshooting with a variac, as well as maybe a scope. If your not trained to work on HI Voltage circuits you should seek assistance with this repair. Theres HI voltage inside these sets even after they are unplugged for a while. sorry i couldnt be of more assistance.

SOURCE: no pic, no sound

Hey Wilt: We had the same problem, for the same model of Toshiba TV. Had it repaired yesterday. Turns out the problem was the power supply (P.C.B). The total cost was $192.66 Canadian funds (taxes and labour all in). Our model was 6 years old, buts its playing like a brand new unit now. Hope this helped ...... Good luck

SOURCE: tv has sound but picture is black

good day.
The crt circuit of the unit might be loose or the the parts inside the board is loose. Have it hecked by a technician first. Minor parts inside might caused the problem.

Response is highly appreciated.

VIORE 32"LCD lc32vh70 Has sound but the screen turned in black


Does it turn black after about 10-15 seconds? My 40" Viore had the same problem. After trial and error, I finally fixed the problem. There is a motherboard with a cable wire coming from one end to another motherboard. 3 wires. If you remove this wire and kind of jiggle it it in, barely touching the contact points, you will see the image stay on longer than 15 seconds. You have to cut one of the wires on the board with all the inputs, VGA, HDMI, power cord, etc. I have taken pics but have not taken them out of the camera yet. If interested, post back here and I'll (hopefully) get them out. But a word of caution: my 40" inch TV motherboard may be different than your 32" inch.

Screen black. polaroid tv 32". have sound TV/DVD Combo TDA-03211C


sounds like inverter board. What it sounds like is happing is your LCD is working ut the backligkt board that allows you to see is kicking off. (as you still have sound) Which could be the (most likely) inverter board, or the power supply board. You can take apart and check for voltage at your power supply. The power supply has a pigtail with large white wires and a connector. Power up with the center back cover off and check your voltage at the white connector on the power supply before and after the screen gos out. If there is no large voltage loss it is your inverter board.
