AFTER REPLACING THE LAMP, I HAD TO PUT THE COVER ON AND NOW THE SCREEN HAS TINY BLUE DOTS AND THE POWER LIGHT STAYS GREEN. THE LAMP LIGH IS NOW ON AND RED


The blue dots are due to a failing optic block. The lamp is only making them show up more obviously. The TV is probably failing as the blue dots will get larger and eventually take over the screen.

Blue dots on my tv screen


The model indicated is a Plasma set and if blue dots in motion (moving) may be either on the MAIN board (processes all signal) or it is even possible to be a problem on the power supply board.

Most likely a shop repair as someone would have to look, order board/s and actually replace them to find which board is bad.

This is the nature of repairs in all Plasma sets.

Only boards are sold and no individual parts.

I have blue dots all over my screen aa well as


Hi,
This blue dot and hue problem is due to bad lcd in your tv as its Sony dlp tv that has optics block, that is also called light engine, it consists of 3 lcds, filters and lamp to produce an image that projects on front screen.
In this tv, blue lcd became defective and complete light engine will be replaced to get it fixed.
As other expert talking about blue CRT (cathode ray tube) that does not exist in this tv and my fellow expert has no idea about this kind of tv, sorry for that.
Hope this info will help you, let me know if you have additional question.
Thanks.

Blue blob


Hello rivas_gab. Before I answeryour question let me explain a little how your tv works. You TV uses is a 3LCDtv that gets its picture from a lamp, the lamp produces a white light brighterthan the sun, the light goes through a square prism and is split 3 ways, eachgoing through a small LCD chip (blue, red & green). Then it travels troughthe light engine where the final picture is produced. The blue blobthat appears on the screen might be caused by one or two lcd chips that havestarted to get burn by the intense heat emitted from the light of the lamp. If that is theproblem you’ll have to replace the entire light engine, the other option isthat you buy the prism with the lcd chips, how ever that almost impossible becausenobody that I know sells them separately. If you decide tobuy, search buy part number, NOT model number, otherwise you’ll run the risk ofgetting non compatible parts. If you’re lookinga place to purchase look for dedicated tv part distributors (my personal recommendation:Discount-Merchant ). Happyhunting.
