That is a bad sign of bad flxible TFT board on the LCD panel which cannot be repaired, you can try reseating the ribbon cables between the LCD panel and the T-CON board first to see if that might be the cause.<br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Please see my basic troubleshooting guide here:</span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><a rel='nofollow' href="http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide">http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide</a></span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"> </span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt"><a rel='nofollow' href="http://s807.photobucket.com/home/budm/allalbums">http://s807.photobucket.com/home/budm/allalbums</a></span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt"> </span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"><a rel='nofollow' href="http://en.wikipedia.org/wiki/Capacitor_plague">http://en.wikipedia.org/wiki/Capacitor_plague</a></span>

Any advice on what board I should replace if the left half of the screen is no good, just showing white and black vertical bars? Right half is fine. Is the panel kaput?

I have a RCA L32HD31YX12 TV. The TV works fine for a half hour and then the screen flickers and goes black. The sound continues. If I turn the set off for a half hour, it works again for another half


You have answered your own question, someone needs to open it and find a loose plug or broken solder connection--if it reacts to being tapped on that is the issue- a physical problem inside.

My hp CPTOH-0602 was flickering and then stopped and now the screen is dark with a big black area in the top left corner


it was a screen back light failure, the lamp get busted in the upper portion of the panel display. to access this part you will need to remove the back cover using a philip screw driver. the back light is covered with metal shielding.to replaced the back light, be careful in disassembling the cover not to damaged the lcd screen panel.

Coulor distortion at the top left of the screen


Hello jordan ashe,

This is an indication that the green CRT is having a convergence problem. This might be caused by the convergence amplifier or by the CRT. Does the rest of the picture look OK? and in addition can you supply a picture of your TV so as I can see what you are seeing and develop a proper diagnosis?


Thank you,

Phillips 42 inch Plasma -Screen Issues!!!


intermittent loss of picture on either bottom or top half of screen is specific to y buffer boards located on left side of screen going from top to bottom when looking at back of tv. the y lower buffer would be the board to replace to resolve the loss of bottom half of picture. if the top half also is going out intermittently could tied to upper buffer as well but just a note the y main board to right of these buffers drives those two boards so in some cases could also be part of the problem. if only bottom half is affected i would recommend replacing lower buffer only

Model 42mf231d/17 42" plasma


If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit
