Question about RCA HDLP50W151 50" Rear Projection HDTV

1 Answer

Black Marks on T.V.

I have a 50" RCA HD T.V. I turned it on earlier in the day and the screen was normal. I turned it off for a few hours and when I turned it back on, there are black marks on both lower corners of the t.v. It almost looks like someone took a permanent marker and colored the corners. How can this happen? And how can I fix it?

What is the life time for the LG 50PT350 panel, it's not written any where


Hi there,

The specification of plasma panel lifespan is somewhat suspect, since the process of determining longevity of the product is based on deductive mathematical calculation of phosphor dissipation, and does not take into account the electronic components and the myriad of problems that can occur.

Whilst all new LG "Full HD" (1080p) plasma HDTVs panels are now rated for 100,000 hours (that's more than nine hours of watching a day every day for 30 years), your 50PT350 panel is only capable of "Std HD" (720p: 1024 x 768 pixels).

As LG have not specified a specific panel lifespan for their 720p models, we can only presume this panel belongs to LG's earlier plasma panel specification of 60,000hrs.

You can prolong the life of your plasma by avoiding excessive use of the Dynamic Contrast & Brightness settings. Sometimes these settings are set to maximum when shipping from the factory, so reduce these settings to a maximum of 60% where possible.

Although plasma phosphors are more resilient to burn-in (including technologies to help prevent it), as a precaution you should avoid leaving static images on your screen (i.e. black letterbox bars, logos, game screens) as these could still leave behind a 'ghosting' image embedded on your screen. Try to watch in full widescreen format as much as possible, to prevent the black sidebars.


Hope this helps....

Hitachi 50" hd TV displaying black lines on screen


Sounds like your YBL-Y Buffer lower board is going out. There are 3 boards here. The Y buffer upper which controls the top half of the display, The Y buffer lower controls the bottom half and the Y-SUS main control those two boards. They work in unison. Usually if one goes out you have to replace all. You can also get lucky and just repalce the YBL and all may be well. Now if they are vertical lines up and down the OSD-On screen display, then this is indicitive on dry solder joints on the D, G E, F boards. Hope this helps...

Sounds like you lost the power supply to guns, now this doen't mean you have to go looking for it, you will need a repair person to fix it. Word of advise, if you haven't had one of these fixed before it can range in upwards of 600.00 or more to fix now days.

There are capacitors on the power supply board that dry out with age. You can identify them by observing the tops of each of them. They have to be flat, not domed. Some of them may be discolored from heat. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

I`ll have to be the bearer of bad news, the image is not burned onto the screen it is burned into all 3 of your picture tubes, which basically means the set is junk because the cost is too high.
