it will have a short in the vertical stage or power supply to it, and maybe even a power supply regulation failure(high voltage) that set the whole thing in motion. I will do some research for you and get back real soon :)

SOURCE: incompatible signal

Check your resolution settings on you playstation 3 menu's. If you are using an HDMI cable, there is a chance that your ps3 could be trying to output at 1080i or 1080p. The unit you have only goes up to 720p and if you set it any higher than that, you run the risk of having picture issues, or not getting a picture at all. Good luck to you

SOURCE: Unsupported video signal

It is possible that Jewelquest changes the screen resolution to one that is not supported by the TV. I am not familiar with Jewelquest, but the typical reason for the unsupported message is a resolution outside of the supported range. The supported resolutions should be listed in the owner's manual.

My toshiba 65hx81 cut out lastnight. All I have now is the red flashing pwer light. Where do I begin? Do you know what the issue might be? Thankis, Kyle


Frist Kyle count the number of blinks on the set when it shuts down, this is an error code related to the problem area., The most common failure in this model is the deflection power supply board. This board provides high voltage to the picture tubes and related large signal circuits. You may want to check the horizontal output transistor for shorted condition, if it is found to be shorted replace it an the flyback transformer as these two work to gether to produce the horizontal frequency to produce the high voltage.

Tv shutting off timer light blinking


Your TV is in the protection mode. First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..

Tv problem


The F27442 uses the CTC203 series chassis and that symptom is very common. If the horizontal output is shorted you MUST resolder the coil in series with the base of that transistor and the pins of the small horizontal drive transformer. When they have been properly resoldered you can put in a new original horizontal output transistor. If the output transistor shorts out again then your flyback (high voltage) transformer is shorted and needs to be replaced.

When the horizontal output (2SC4927) is shorted it means one of 2 things is wrong - the horizontal drive transformer has cracked solder joints or the flyback transformer is shorted inside. If the solder joints on the horizontal drive transformer (the small grey transformer connected to the base of the horizontal output transistor) are cracked then the set will play for a little while and then the parts you just replaced will again be destroyed. ALWAYS resolder the driver transformer when replacing the parts you mentioned! When I replace the parts you mention and I do not see any obvious cracks on the driver transformer then I unsolder the B+ pin of the flyback (labeled 135, for 135 volts) and put a 60 to 100 watt lightbulb (drop-light) in series with the flyback. This means that the 135 volts B+ goes through the lightbulb and then into the flyback, so the lightbulb acts as a current limiter to protect the horizontal output. When you turn the set on the bulb should glow no more than about half bright and you should hear the high voltage come up, but you should not see a picture. If you turn the set on and the bulb glows as bright as if it was plugged into the wall then you can bet that flyback is shorted and must be replaced.

Check the FBT and the Horizontal Output Transistor also.
