Having problems with your Flat Panel Televisions ?

Sanyo dp46848 has a washed out lcd screen... high brightness, very faint picture and OSD with moving warning about no signal present. Brightness, contrast and color controls have NO effect on the pict


\015 Video Signal was subbed into the T-Con board from a similar Sanyo Dp52848 that had a damaged screen, both use the same Main board with minor differences because of screen manufacturer (Sharp and AUO) so even though the LVDS cable was different at the DP52 T-Con board. Hooked the LVDS cable to the same connector on the DP52 Main board and NO change in the picture quality. Should prove that Main board and power supply on the DP46 are OK, suspicions are that either the LVDS cable or T-Con board are is bad. Subbed a T-con board bought of Ebay that arrives in bubble-pak (NOT the anti-static pink kind) so I believe the board was suspect due to static damage during shipping. Picture was pretty much the same except for "artifacts" that weren't present before appeared on the screen randomly. Disconnecting the LVDS cable from the main board resulted in a completely black screen except for backlight leakage. Suspect either the T-Con board or LVDS cable, hopefully NOT the screen. Your thoughts?\015

When the blue on the hair or around the people disappear the colors are no more bright as I have to put the brightness almost at 100% Do you know how to solve the problem ? thank you very much for your assistance

HDMI Inputs don't work (and I've tested my components with another TV). When viewing on Component 1 input, the picture has blotchy color, like water colors. Adjusting color and brightness doesn't help. The tint control has no effect, and in fact, the tint slide looks funny on screen. The audio control no longer allows selection of the A/V external. The only setting it allows now is TV. Reset does not change the symptoms.

Purple? Would that be magenta? That's what you get when you lose the green color. Lower brightness may be due a shift in one of the power supply voltages. I'm not familiar with the layout of this model, but the first thing I'd do is inspect the power ... Flat Panel Televisions

Hi I have an LG 42" plasma about 2.5 years old. When watching late at night with low sound so as not to disturb the household the screen buzzes when a bright screen/white sky or even with no signal and just the screen savor comes on and moves a round. Is this the power supply getting ready to pack up as is very annoying.


I do not think the buzzing is coming from the screen itself. It is either coming from the transformer on the power supply or the Sustain boards(labelled X-main and Y-main). My money would be on the sustain boards. Please remve the back cover and veri ... Flat Panel Televisions
