Can i fix my tv screen is red


Toshiba 36A10 36" TV is the model you have indicated---

If the screen is all red and or too bright (no green or blue can be seen) the problem is in one of two places: Either a shorted picture tube or the board that plugs onto the end of the tube.

That board sends red,green, and blue video and information to the picture tube via 3 pins on the tube (the K or cathode for each).

The set will have either 3 IC's on that board or 3 transistors, or a single larger IC for this.

to troubleshoot this:

I would locate the Red Cathode and unsolder that pin at the socket on that board--takes red out---if you have green and blue picture then---it is either the IC/transistor that feeds that on the board or the tube itself.

If it has 3 chips (usually will each have a metal plate attached for cooling) you can either remove and replace the red one OR what I do is swap it with the green or blue chip---if suddenly you now have a blue or green only screen you know that part is bad--simple as that.

If for any reason the picture tube turns out to be bad--you are finished and so is the set= way too expensive to replace it.

Let me know if you have questions or need advice.

Samsung model hlt4675sx\xaa projection tv wont work. the stand by/temp light flashes red and the lamp light flashes green? it makes the sound that it makes when it turns on but no picture. we looked at the...


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

Clear but only blue/green color


Do you have a component cable hooked up to the TV? (cable with RCA connections Green/Blue/Red/White/Red)

If so you want to check that the red cable is tightly connected to both ends (TV and whatever it is connected to).

Good Luck...

Turn on pic turns red with thin bright red horizontal lines


Sorry to say, but that's usually the sign of a bad picture tube. One of the elements inside the tube shorts and you see the picture you describe, and the set shuts down due to high voltages getting to places it shouldn't. There's no solution except picture tube replacement, and that is uneconomical. You're better off replacing the TV when the tube goes bad.

Hi
Problem is probably PSU REGULATOR, STRF6668B.
I wouldnt recomend you repairing this yourself as there may be other components that will require checking.
You could end up blowing the replacement regulator.

Click click repeatedly faded then red blinking light


Go to the video menu and turn the color control to minimum. Determine if you have a black & white picture or is it green & white. If the picture is greenish, you have a problem in the screen circuit or possibly a bad picture tube. If the black & white is ok then I would suspect a problem in the chroma circuit such as a bad video jungle IC or a crystal. However, because your set had a red blinking issue prior to your existing condition I would lean towards the picture tube as the source or your troubles. You can try a simple test to determine if you have an intermittant short . Take the back off the set, and with the insulated end of your screw driver, very very lightly tap on the neck of the picture tube near the socket. If you see green flashes or hear loud snaps in conjunction with your taps or the green tint goes away, chances are the tube is the cause. If so, you might try installing an isolation transformer on the picture tube. Good luck

Toshiba 32A41 TV -- color problem


Toshibas are notorious for developing shorts in the inernal guns of the picture tube. In your case the green gun is shorted to G1. The noise you heard was an internal arc between the elements. It is unfortunate however, the repair of this problem usually requires the picture tube to be replaced. Sometimes a savvy technician with sencore picture tube rejuvenator can remove the short. This however usually does not last. Scrivitron
