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

1 Answer

Vertical lines I have a JVC HD-70G886. Today when I was watching it vertical lines appeared in about 5 areas across the screen. I checked input sources and it was the same for all. I had replaced the lamp about 2 months ago and it has worked great until this. I unplugged it and let it cool for a couple hours. When I turned in back on the same lines showed up about 15 seconds after I turned it and seemed to get worse. Is it a power supply problem? Any suggestions?

    I have the exact same issue. TV guy told me today that it's the light engine but I'm doubting that prognosis now.

Get some freeze spray from radio shack then try placing a little spray on each chip on the video board and power supply board and each time you spray a chip look for the picture to clear up. When the lines go away you have located the bad IC.

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...


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.

4 thick black vertical lines showed up on my hd-70g886 today. any cheap suggestions? or should I throw it away?


That is a defective Digital Light Processor. It is part of the Light Engine Assembly. I definitely recommend NOT repairing it. Average cost to replace is around $650.00 if still available. Mfg's want DLP sets off the market for to many problems.

Lines across my tv where the picture is reversed


You have bad capacitors in the vertical deflection. And you will have to resolder the vertical IC as well. Replace the caps in the area of the vertical IC. Find a TV tech or hobbiest to do this!

Vertical lines appear on the screen.


It appears like there is a bad capacitor in the horizontal circuit. Try to put a fan near the ventilation trap, just for a test.
the part cost almost nothing but having someone to your house is expensive.
Your decision.

TV: bright line across black screen for several hours.


vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch
