Question about Hitachi 53UDX10B 53" Rear Projection Television

1 Answer

Screen seems really red at times and left side missing several inches of display

The IC's were recently replaced. Now faces seem really red and reds seem almost purple or orange at times. A small portion of the bottom of the picture and several inches of the left side are not fitting on the screen. What could be causing this?

Advent tv displays green


If you are saying no red: The model indicated here Recoton Advent Advent Q1435A TV is a 14 inch set.

first it may be cheaper to replace than repair--That said if no red look to the small circuit board at end of picture tube (it plugs onto the tube).

It will have either individual output transistors or a single IC.

What (if only one color missing) I would look at is the bottom side which faces to the rear---a circle of solder connections--possible one is broken--there will be one for each red, green, and blue--not always easy to see but if any of the solder connections look cracked or even broken loose-----

Red vertical line down right side of the screen


hi

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.

Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel

try this

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
