Question about Toshiba 42H83 42" Rear Projection HDTV-Ready Television

1 Answer

No picture, no sound, no menus

The little red "power" LED next to the power switch comes on, but there is no picture, no sound, no menus, no sign of anything working at all. It worked fine this morning, but there was a brownout in the neighborhood for about 15 minutes, and now it doesn't work. The TV was "off" at the time. I have always had it plugged into a "Monster Cable" surge protector. The outlet is good. I looked inside the back, and there is a small fuse on the circuit board next to where the power cord connects, and that fuse is fine. HELP!

Samsung TV (model UN40H6203AF) 40" LED. No picture, have sound. Flashlight test can see faint menu screen. Have replaced power supply & main boards to this point. Ideas as to what to do next?


Hi Terry,

If you can see the faint picture in flash light means the power supply and the main board is working. The real culprit is the backlight. Even one bad LED in the backlight will switch off the whole array. To repair this fault the panel has to be opened and the defective LED or LEDs are to be replaced.

This is a complicated, delicate and risky job and must be attempted by an expert only. You may end up damaging the screen permanently if you have not done it before and try to DIY.

My samsung HLT5075s has a popping sound coming from it. The sound comes faster and faster and then the tv makes a Bleep sound and shuts off. Do I need a new power supply or a ballast? The picture is...


I had this problem too, popping coming from the internal speakers it seemed. I typically use my surround sound so the internal audio isn't necessary for me. You can take off the back and down next too all the inputs on the right hand side (if facing tv front) you'll see a little gap between the connector housing and the base of TV, there is a little cable connected to circuit board that is red, black, and yellow i think, pull it from circuit board. this disables audio from the main board traveling to front of TV. Problem fixed. Ps ..this also cuts the red led in the front..

Just a thought, but check all of the pico fuses for a blown fuse. The pico fuses look like a small yellow resistor. Some Hitachi's are famous for having a blown hi-volt ceramic capacitor and a blown pico fuse.
I think the red led on is a short protect indicator, but I could be mistaken.

I have a Philips Plasma tv 42pf5321d/37 with sound but no picture


Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Best Regards and Smper Fi

I Think NO expert can help this problem because it free answer


I think I may finally have the answer for the "black screen of death" for the 42" Polaroid LCD televisions. I was having the same issue with the screen going black after a couple minutes of being on. I would shut it down then turn it back on and it would work again for 5-10 minutes. On the "power board" which is the board on top, there is a little red light that turns on when the screen would go black. above that there are 4 little switches, the lower on says BURN. I simply switched that over and the television has been working for 2 days for 8 hours + each day. Hope this help. Let me know

No Picture & No sound. Red LED, Green LED, Red LED.


If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.
