? about a KP-43ht20

I just aquired this set and have been researching the convergence repair, all the symptoms are there. so i proceeded to get the board out and check the fuses before i ordered the repair kit and all the fuses are good is this possibly and indication that i may be chasing the wrong problem. also the chips also have a pink mark on the soldering pad, does this mean they have been replaced before? thank you 

plasma display panel basics

soniq QSP422T 42" plasma

LGEPDP 070111

model 42X4

 

am an old CRT electronics tech been out of the TV scene for many many years. dont know bugger all about plasma's. this TV has np ns, power supply all good, but the LGEPDP board model 42X4 has a blown fuse FS1 and and VSS is short to ground.

there are 2 long ribbon connectors that connect to the Plasma Panel. I guess this PCB is like a LOPT generating HV in CRT terms.

am only aware that plasma's have X and Y sustain boards and am guessing this is one of two.

Sony KP51WS500 convergence chip problem... fixed, but not the right way?

We have a Sony KP51WS500 projection tv that we got for free on Craigslist. The previous owner didn't tell us what was wrong, so we turned it on and googled the symptoms. It had 5 blinking lights at startup, the display was bowed, the colors weren't in convergence, and in manual convergence PJE mode, only the blue would move. We ordered the convergence repair kit from tvrepairkits.com and checked fuses with our multimeter. There was one blown 5 amp pico fuse on the G Board and two blown 3.5 amp picos on the D board. We replaced those three fuses and also both IC chips on the D board.

Phillips 60PP920217F Picture not centered

I have had this TV for years now, and it wasn't until I switched to ATT u-verse that I noticed my picture is not 100% centered. The guide that ATT uses go all the way to the left so on 4 digit channels like 1440 the 1 is cut off.

I have read the manual, here's a link to the PDF of the manual

Help with Samsung LCD screen solid black line across screen

Hi,

I am after some advice reference a Horizontal black line that has appeared on screen throughout all media displayed, satellite, DVD, Blue Ray, PS3 etc

I have a Samsung 46" LCD 1080. The line is very thin and seems to be only 1 or 2 lines of crystals affected and fades out from left to right with the image returning in the last 2-3 inches of screen.

Is this a known regular fault?  Is there a possible fix for this?

Thanks

Samsung HCM4215W

Have a Samsung HCM4215W and it just wont stay on. After I turn on it will blink for a second, turn off and turn itself back on again.

I have unplugged it from the wall, let it sit for a day, but ..it still won't stay on.

Any suggestions??
