    Same issue with my HP picture but sound. I've seen a couple of post that say to replace they Y-SUS board only and other posts that state that you'll need to replace (2) boards. Does replacing the Y-SUS board (TNPA3243AB-PA) only fix the problem?

    Same problem. Power on, sound, but no picture - just a black screen. I called HP and they told me it was the Y-SUS board. And for only $620.00 they'd get someone tyo come out and fix it. Which, of course makes the product a disposable TV - because to buy a new, presumably better TV is about 800. The TV is 2.5 years old. It is ridiculous.

    Does anyone have the schematics to change this Y-SUS board? My TV is still mounted on the wall but it can pull out a little. Can the board be changed without dragging the thing off the wall?

The problem is the "Y-SUS" board located inside the set on the left hand side under the left vertcal brace. It has a large aluminum heat sink on it. The part can be ordered from Union Electronics at:

Look up part number: TNPA3243AB-PA It lists for about $115 plus s/h

Picture dimmed. can see the picture and in menu increased the backlight to max but did not go back to normal. checked eco settings and did factory reset. still very dim but can see the picture.

Yah kindly follow this tip. After loosing the back cover when the tv power cord is removed from power socket, check for bulged or defect power capacitors in both the primary & secondary side of the power pack if found any kindly replace it with the actual or equivalent value as this electrolytic capacitor defects is much common for Samsung power packs

I have a memorex. I am getting sound but no picture. When powered on, the memorex sign shows up but then no picture just sound. Also makes a slight screeching sound for approx 10 sec. when powered on.

I guess the blanket draped over the TV is intended to give it a "timeout". Anyway, you will likely conclude eventually that the internal power supply has failed.

I have a 50 inch insignia plasma tv just turns off have to unplug aand then plug back in and it will turn on run for an hour or so then happens again

this is why we all stay way from plasma tv.
1) there not the best tv out there.. never was and never will
2) check to make sure that it;s set up right.
3) check to make sure that there nooo other plugs in the wall other then the HDTV...4) i hope that soon or sooner that we all would use 1 HDTV and that is Sony.. :D

now i know my HDTV i worked with them alots of time. and others other thing u have to watch out for is overheating.... if the fan does not kick on then thats the reason why it will not stay on.

Picture blinking

Most likely you have a few dry capacitors on the power supply board, if you have any electronics experience, remove back, locate power supply (usually has large heat sinks) and c
