Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

54inch Hitachi TV has double figures and colors red, yellow-not normal. Set approximately seven -eight years old. Lost remote control and direction book in moving. Is the set worth getting fixed? Generally...


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

RCA Entertainment Series 32" Plus Gold, GEMSTAR, xbox ready has been in the shop twice so far. Transformer replaced and 6 months later the picture suddenly had horizontal white lines that gradually spaced apart more from top to bottom and it had a gray hue and fuzzy, but I still watched it for 3 months that way. Today I turned it on and about a minute later I heard a loud crackling sound coming from the back and the picture disappeared, screen went black. Is it worth fixing again?

Sony 60" LCD projection TV has yellow screen discoloration


I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
Good Luck.

Picture separated on 1/2 of screen


This sounds like a convergence problem. This is a common problem that is usually fixed 98% of the time by re-placing the STK392-020 ic or STK392-110, and check the fuse devices on the covergence PCB. I'm sure the actual parts numbers depend on the peticular brand. Good Luck!
