I have a 2004 sony 42 inch dlp the back of the screen is blue what is wrong with it


It may be the optical light engine---usually the whole screen will not be a uniform blue but just areas----the lamp shines into the engine and the first part it hits is the blue---some damage can happen since the lamp can burn that area with its heat---best way to look is go to a unused video input and look there.

TOSHIBA 57LX177 SHADOW SPOT CENTER OF SCREEN


If my research is correct you recently replaced the lamp and then the "shadow spot center of screen" appeared.

Three possible reasons I can think of for this:

Something wrong with new lamp or on face of lamp--never touch the face of a lamp as oil from you hand can leave a residue and damage the lamp or cause a image issue.

Something inside on the optical lens or even the mirror causing this--not likely but possible.

A defect in the optical light engine in the set---usually if heat which comes from the lamp damages the engine it will be a color and not black---engine has a series of lens and baffles inside that heat can damage--causes minute separation inside of the lens etc.

If the old lamp works at all try putting it back to see if same issue--did you replace just the "bulb" in the housing or the whole cartridge?

If remove new lamp look at it and where it faces--usually a clear lens faces it and if some dirt on that..........

Hi Kevin this type of problem needs to be serviced. What you see is liquid trap in the LCD screen that might damage other parts of the LCD if you wont fix it. If its under warranty call the Mitsubishi support.

My husband fell into the television and the front screen popped out. Can we put it back in ourselves? It is not broken


You should be able too. You will need a torx #20 driver bit to remove the bezel around the screen. Carefully... The screen can be easly scratched

RPTV Screen Repair

You have 3 options:

1. Visit local service shop with model number, he can check his TV graveyard for a possible replacement or order part then install. Problem usually solved. Screen from $200 to $500.

2. Locate model number, work on the part number, search the internet and order online. (includes the possibility of dealing with a wrong or damaged part that left the warehouse like "new")

Then get tools and start a TV dis-assembly project. Install screen (50-50 chance it faces the correct way). Usually they are easier to take apart than put back together.

3. Scrap TV if you can not get a used screen for $100

I have a Toshiba 52HM95 and the power cord was cut. How can I get a replacement power cord.


make sure you have the set UNPLUGGED!





Manufacturer
Toshiba Part Number 23372117 Description POWER CORD, 125V,



Andrews Electronics in the LA area has them
in stock--about a 3 dollar part plus shipping etc.


There is a easier way to do this if you have someone who can solder.

What you do is spice the cut cord back together---off set two cuts so the splices are not side by side.

One side of the cord will be smooth and the other have lines or rough. What I do is strip back until I get 1/4 inch bare on all 4 connections and then get some heat shrink tubing (radio shack has it) You slide a piece of the tubing on one side BEFORE YOU SOLDER TO TWO SMOOTH ENDS TOGETHER---Do not wrap them--solder them just tip to tip and repeat it with the two rough ones also putting a piece of the tube on first.

When both splices are soldered you slide the tubing back down over the place where you soldered and use a match or hairdryer to shrink it--it will shink down air tight over the connection.

It is very important you off set the splices so if the heat shrink comes off they are not side by side and can touch.

FYI--BUYING A NEW CORD? MOST OF THESE CORDS ARE SOLDERED INSIDE THE SET SOMEWHERE--which is why I suggest it is easier to repair it

if this has helped you rate this as I do it here for free.

We have liquid trapped between the screens, how do we remove the front screen to get it out


If liquid, what did you spill?
There are two screen on a DLP. One is a Fresnel lens that focuses the light from a point source to parallel rays. It has circular ridges that are like short segments of a normal lens, just weighs a lot less. The circles get tighter together as you go to the edge. Then the outer plane has horizontal ridges that concentrate the light in the viewing area on eye level to increase the brightness. They face each other and should be close but not touching. Anything between them is a problem--liquid or not. You may find on AVS Forum for your model a description of disassembly for the screen--it is likely more tedious than difficult. Have a large work area. Do not scratch either lens and put it back the same way. There will be some trick in taking it apart. If the outer screen has been pushed to hard they may have stuck together, hope not or you may be buying the assembly. -Ken

RU -44, small "pink" spot on screen.


Green is missing from the area where you see the pink (actually magenta) spot. This might be due to a large amount of dirt on the green lens. It may be due to damage to the face of the green picture tube. You need to remove the front screen so you can look into the lens and determine that.

Depending on the make and model of TV, the screen may be held on by snap fasteners and come loose when you pull on the plastic bezel surrounding it. Or the bezel may pull off to reveal brackets screwed into the cabinet that secure the screen. Or there may be a trim strip under the screen that pulls off to reveal screws. Remove those and the screen will swing up and off.

Once you can see the lenses, clean them with a soft rag and glass cleaner. With the set on, look down into the lens and you can see the face of the picture tube. If you see a dark spot on the face, the tube is damaged and would need to be replaced

Problems after convergance IC fix


try not to mix areas in the tv chasing several problems.
  1. Lets get back: i hope the tv was doing fine before to start digging into it ( was it?) Was the tv complete tested before to make sure the buttons were working all and the audio was there. I mean each part of your tv has different solutions:
Think you have an animal with several heads now:
  • the buttons in the panel (some working is good! some others can be replace and there it go all panel works)
  • audio mute (maybe no signal and automatic mute is there. or maybe really audio is damaged. Leave it at the end is another area.
  • Touch focus is the the program controlling convergence digitally talking. If the tv is not yet fix with the amplifiers then the problem still landed in another area not in the digital control.
Finally Start over! Get into de convergence and get your three tubes at least close to convergence (forget auto focus now) three screens together or almost but three rectangules with white noise. No having GUI you mean OSD (i gess) (on screen display) channels appearing when you push that button or audio level line or menu letters (several buttons have to be touch to make sure of there is not OSD.

if the tv has not white noise the screens are without convergence. you are digging in a set with maybe 5 problems the three you told me plus the other posibilities im gessing and i hope you don't have. So slow down with the repair and try step by step. bye now.
