Question about Toshiba 32A50 32" TV

1 Answer

No Color I had an issue with the screen turning to static a while back ( and no the cable was not out). Took it to a tv repair shop in my home town and he suggested the easy fix was to use a video input rather than the antenna. That was fine (and cheap) and it worked for a while. But now the issue is that the color is now gone regardless of input (cable, DVD, vcr, etc). Anyone have a clue what the issue may be? Thanks in advance for the help.

Color halo's on screen

On old style CRT TV's there used to be a Degaus button that nuetralized any static build up inside the tube, and corrected those "Halo" or Color ghosts on the screen. You can take a very strong magnet and pass it a few inches in front of the screen. Try sweeping the magnet across from left to right until you have accurate colors again. (Takes less than 1 minute)

I have a CR202 EM8 and I have had to do this a couple times over the years. On my cable system I can tune in a Color Bars pattern on channel 2, which makes it really obvious where the static build up it affecting your colors.

Good luck...

How do I change the color wheel on my samsung HL-P5663W. I have already removed the lamp and loosened screws for the lamp housing. Doesn't seem to want to come apart. Am I on the right track?

Samsung's digital light projection (DLP) televisions use a spinning color wheel to create the colors that are seen on the screen. If the color wheel becomes misaligned during use, it will become damaged and have to be replaced. Replacing the color wheel on a Samsung DLP television can be done at home, once a compatible-sized color wheel has been bought from a TV supply store.Replacing the color wheel yourself will void any Samsung warranty that might be in place, but is the only solution for getting the TV working again in as short a time as possible.
Put on the anti-static grounding strap to keep static electricity from damaging the internal components of the Samsung DLP TV. Turn the Samsung around so that the back is facing you. Make sure the Samsung is unplugged from the AC socket.
Use the Phillips screwdriver to remove all of the screws from the back panel. Put the screws aside. Pull off the back panel.
Loosen the two screws from each side of the projection bulb's case. Pull the projection bulb out. Put the projection bulb aside. Use the Phillips screwdriver to remove the two screws from the left side panel. Pull the side panel and the circuit board attached to it out carefully and put it down so that the cables attached to it have not been pulled out.
Take a picture of the power cable's position with the digital camera so that you can put it back correctly later. Pull the power cable out from inside of the Samsung's case so that the center panel is free to be pulled out. Remove the two large headed screws from the center panel with the Phillips screwdriver. Remove the top two screws holding the panel to the plastic case using the Phillips screwdriver.
Slowly slide the center unit out a few inches. Take a picture of the projector lens' positioning with the digital camera so that you can put it back correctly later. Unplug the two cables from the left side of the center panel. Unscrew the sensor switch using the Phillips screwdriver. Slide the center panel completely out of the Samsung and put it down on the clean cloth. Blow off the color wheel assembly with the compressed air.
Use the tweezers to remove the green plug from the top of the color wheel cover. Use the tweezers to remove the two cables at the side that are coming from the color wheel. Use the Phillips jeweler's screwdriver to remove the screws from the top, front and back of the color wheel cover. Slide the color wheel cover straight up to expose the color wheel.
Use the Phillips screwdriver to remove the three screws holding the color wheel to the color wheel assembly. Lift the color wheel up and out of the color wheel assembly and discard it.
Position the replacement color wheel in the color wheel assembly. Reassemble the color wheel and reassemble the color wheel assembly. Put the color wheel assembly back into position in the rear of the Samsung DLP TV. Reassemble the Samsung DLP TV. Plug the Samsung DLP TV back in for power. Turn the Samsung on and enjoy seeing the colors displayed properly again now that you have replaced the color wheel.

Blue,red,green lines on top of screen for couple months. Now tv wont work.

The foldover is because of a bad capacitor in the vertical circuit. Given the "new" sympotom of a dead set, I would suspect that the vertical IC has failed. This should be a relatively simple repair for a TV shop. If you wish to attempt a repair of this yourself, update this and confirm your model number and I'll post more details and instructions.

Cable connection generating static on screen & noise

Hi, it sounds like ya most probably gonna haveta resolder the Cable Connection Socket internally.. they often fracture, OR perhaps it is the Actual Cable Connection Plug itself?.. maybe you need to remake this input connection? Indeed it sounds as if the Earth Shielding is making bad contact...

RCA F27683GY 27" TV

I bet both TV's are connected to cable TV? This was a problem and required different fixes. There was a law suit against RCA for this issue as they said there was nothing wrong with thier TV's that it was a cable issue. You will probably have to contact a local TV shop for repairs as just audio boards won't fix the problem.

ProScan PS32500 32"-Picture has white static line & Static/burning smell

It sounds like the circuit board is arching over somewhere. It could be as simply as cleaning and digging out the carbon mark to stop the arching. This is most likely the screen or focus voltage causing this, if there are no parts that have broken down. This will damage the printed circuit board and make things worse the more you let this cook. This could be dangerous for you to mess with because of the high voltage present, so my best advise would be to get this into the repair shop as soon as possible before this board burns up. It should not cost all that much if the CRT board can be repaired. Good Luck
