Re: Help Please NO Picture!

The high voltage display power is down. First step is to measure the B+ voltage with a voltmeter to see if you have power to this section. It should be about 140 volts so don't touch it. Having this kind of failure after 3 years is unusual. Was there any kind of power surge etc that may have coincided with it?

Picture goes black on and off but sound still on

This could be a sign that the picture tube is starting to fail. To prove this try the following: Please note that there are potentially dangerous high voltages present inside the set, so be careful.

Unplug the set and remove the back. Locate the flyback transformer (lower right when facing the back of the set and has a lare red wire coming out the top.) There should be 2 controls on that part. One should be labeled screen the other focus. Turn the screen control slightly clockwise. Turn on the set. If the blanking stops, then this will "fix" the problem for a short period. This is not a final fix, but a short tern remedy to give you time to locate a replacement set.

If the above does not resolve the problem, please update this and we'll investigate further.

I have a JVC tv only 1 year old and the picture is getting dark.

Sorry to tell you but JVC is a well-known un-reliable brand and if it's cheap, probably even worse. U may have screen burn from leaving a games console on while plugged into the tv, even if its not showing the game, it will burn it onto the screen. :(

Please, Help me fix my TV

It sound like you have abad picture tube. Iknow this is not the answer that you want to hear. Sony's have video blanking circuit built into the video processor(in the jungle IC) when the emission of all three gun fall out of an acceptaable range. the screen blinks and when you turn the screen control on the IHVT all you see is re-trace. Some times there is a current limiting resistor in series with on lead of the heater on the crt board. By changing this resistor from 2.2 ohm to >.1 ohm @1/2 watt you can sometimes increse the filament voltage to the point that the blanking stops. This is only a temporary cure not a fix. The picture tube is probably bad. Scrivitron
