Question about Toshiba 50H81 50" Rear Projection Television

1 Answer

Picture is strobing

Imagine the flat screen is a sheet, and someone is flapping it forward and backward. That is what my picture is doing, it is strobing, for lack of a better word. It does it on different inputs, so it is the TV, and not the cable or cable box. It just started that today. I have unplugged it for a couple hours to see if it will reset or something. Any other suggestions? Is this something repairable or is it time to get a new TV? We have had it a couple months shy of 5 years.

Re: picture is strobing

The problewm of your unit is in the chroma section. if you find a intermittent trouble my sulotion it could be a loose contact layout circuit. and if your not inclined with this job contact for a service technician.

How do I get rid of smudges on WD73642 screen.seems to be right in the glass

Hello. There are three places smudges that are seen in the picture can be found on a projection TV, the lens, the screen, and most likely, the mirror, but none can be discounted. All three can be accessed by removing the bezel and screen assembly. Most of the screws are around the edges from the back, and some are under the flap that hides the front controls. Good luck!

Rca hdtv dlp screen flashing

Sounds like it could be the power supply. Try changing the brightness of the screen and changing picture modes like movie or standard. If this causes the flashing to change in severity, it will most likely be the power supply board

Tv screen only shows half of the picture ?

I would imagine the bottom or top half is black. My first suspicion, the vertical IC has bad grounds and needs resoldering. Do not short the pins together with excess solder! I would certainly start there for repairs. Thanks for asking and show all hands of support!

I have a 60 inch mitsubishi flat screen n i someone shot an bullet thru my tv n i would lik to have a quote on how much would the repairs be?

Sorry tv not repairable,the picture screen panel is broken or damages.The tv picture screen panel are 90% important to the tv and it is limited in production by the tv corporations,no where u can buy tv picture screen panel except the tvs corporations themselves.By replacing the tv picture panel,will cost the same as a new tv,by replacing the picture screen panel alone,because of it limited production and important to the tv itself.Sorry this not worth as a whole tv anymore,now tv only as salvages tv for it electronic boards for parts only now.

My sony wega 60 lcd projection flat screens picture is getting darker and the lamp light will flash every now and then

That is a typical lamp failure, dimming of the picture, eventually the bulb may go out from time to time causing the picture to come and go, it is time for a new bulb. The bulb is located under the front panel, there are two thumbscrews on either side of the set in the back, loosen these screws and pull off the front panel, the panel has some snaps, so it will not come off easy, tug on it and you will hear several pops indicated the plastic retainer has let loose, then you will see a door near the center of the tv with another thumbscrew, you bulb is under this. Flap.

Power supply for dmtech wt20xt lcd tv

I have DMtech 20" with intergrated DVD and had the same problem- blue light lit on power switch but no response on power up.
I noticed that when the power cord was unplugged from the back of the TV the green LED on the power supply would brighten and consequently dim when plugged back in. Sometimes the blue light on the power switch would strobe very quickly but you had to look carfully for this.
I repeatedly unplugged the DIN type power plug from the back of the TV untill the green light on the power supply stayed a constant bright and there was no strobing on the blue light on the front of the TV, when I powered the TV on at this point the button worked again and the tv powered up with the silly tune then life in the screen. I did have to do this a good few times (I'm tenacious) but it did work!!!!!
Hope this helps someone else, cheers.

Problem with the picture

You need to replace the convergence ICs in this TV set. If you know how to solder and work on printed circuit boards and can follow a circuit diagram, this should really not be a difficult thing to do. If you do not have ALL of these talents, play it safe and call in a pro to assist you in this repair as this TV set is NOT the place to be experiementing around inside of. Good Luck
