Vladislav was able to fix his TV by replacing some defective capacitors in the power supply.
The locations of the defective capacitors are C523 and C524. The value is 0.22uF 400VDC or can use 600VDC as well.

You can also buy the entire power supply assembly by clicking here.
Good Luck.

SOURCE: 42 inch Plasma - Samsung

You need to replace the Y scan board. Sadly, all of the PL4260 models have the same problem... its just a matter of time before it blows. HP has offered a "free fix" but only to those sets that fall with in their so called serial range of those with faulty parts. Like I've said in another post... I called HP yesterday (3 December 08) and they admitted to having used sub standard parts in all of the PL4260 models, not just the serial ranges they (HP) stated.

HP isn't going to fix yours.... and I'm willing to bet your serial falls 1-3 digits outside of the "free fix" serial.

Solution: you will need to purchase TNPA3243AB-PA and TNPA3242-PA to fix your issue. Or you can go ahead and let HP come out and fix your tv for $700+ The difference, you order the parts and fix it yourself...$250-300 plus your time and effort.... you pay HP $700+ for their tech to order the same part from the same distributor, and they put it in for you... either way, you're not getting a warranty or at least thats what they told me....

SOURCE: Samsung plasma all black screen

Black Screen come from three areas. 1- Power Supply Board 2- Inverter Board 3- Processing Board on the LCD. Since the Power Supply Board was replace, it easy to troubleshoot where the problem. lies If you cannot get the backlight, then its the inverter board. If you can use a flash light on the TV screen and can barely see the images, then the problem is indeed the inverter board. If you cannot see any images when using a flash light, then the problem comes from the LCD processing board. Let me know if you have any success. Mike

SOURCE: LG 50inch Plasma received loud sound then went black

I had the same problem with my LG 50 inch TV that I bought from Best Buy in Nov 2006. Fortunately I had the service plan. They had to replace the power supply board as 9 capacitors popped, so the TV would turn on them pop and go black and turn itself off. The TV has been a pain. I have the built in DVR and that has failed twice. I have had 3 repairs through best buy. One more time they owe me a new TV when they come out.

We have a Samsung PS50Q91HDX Plasma Tv which is not quite 3yrs old. Ever since we have had it, it turns itself on & off at random but this is not the main problem. Last night we were watching a show...


This is weird. I also have a plasma 50" model PS5Q91HDX and on the 5/02/11 the screen went blank when my friends daughter was watching a Wiggles DVD. The image kept coming back, flashing a scene or two before going black again. But the sound is perfect.

I wonder what is going on? Is anyone else having trouble with their 3-4 year old Samsung 50" TVs???
