Question about JVC HD-70G886 70" Rear Projection HDTV

1 Answer

Green and Red (thin lines) across entire screen [JVC 70 G886 HD TV]. Screen went to all green (wide and thin) within 1/2 hour and picture hasn't come back. "Input selection" box is visible and clear without any vibration; TV has sound. Screen went green only after I scrolled through the 'input menu' and returned to the prime cable input. I just changed the bulb yesterday. There is also a faint very high pitched sound coming from the TV...or surge protector (even when the TV is 'off'. Please help...I love this TV...even if it is bulky.

Try a "hard reset" first by unplugging the set for 30 seconds. and if no help, you may have a problem with the SMPS power supply, it might have a bad capacitor or two by now. Worth repair if engine is good compared to a flat panel.

SOURCE: no red when hooking up component cable for dlp hd

Check the red cable this is where the red comes from, you may have a bad cable, maybe use the blue or green one just to see if the red will come through, it can be the cable box or the tv or the cable itself.

The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?

Yes the red tube is shorted. I will post a link to the site where I work as they have an entire AV48WP30 with a bad tuner they are selling parts off of including the Tubes. they also provide free info on how to switch out the tubes as a unit which is a fairly easy job. Heres the link.
