you can go to www.PartStore.com enter you model#

You need to do a lamp time reset in the menu.

Possible blown capacitors on circuit boards in the TV or power supply if it's separate.

Hello, you can go into the menu and rename the inputs to what you want example: input 1 can be cable box, input 2 DVD etc. In the menu, go to "inputs" to the side of each input there are several name choices to choose from....tks

I would check fuse and Power supply first

on the mainboard (green board) whilst the tv is on but it dosent matter if the screen is black.. feel the main chip... it should be silver and big in metal... feel if it is hot if it is very hot then your tv is overheating and might need a fan at the back or new mainboard

I think its battery has some problem. If it is genuine remote of the TV then you should take it to the technician.

Your convergence has failed. This is a very common problem on most projection tv sets.

thats the white balance failure which is usualy caused by a failed Video out IC on either the Red, Green or Blue CRT drive boards.

First is the model listed here does not use a bulb, it has 3 picture tubes. What is actual model number as I think wrong one is listed here.

It is a set with issues with the 3 picture tubes but it is quite likely if you locate the red screen control and turn it down just a little you can correct this problem.

red and green lights repeat but tv not start

tried first to look in the user manual if you have. if you don't have go to menu and then select color set up you can now adjust the primary color.

If in shutdown the power light should continue to blink a specific number of blinks which is a error code.This set is prone to bad picture tubes (has 3) so depending on code may be a fatal issue----sets will before flash bright red, green, or blue when this happens and shut off.

If you have already changed the aspect ratio on your TV, then change it on your cable or Sat box. Your TV appears to be operating normal.

The flash focus is a joke in these sets--only adjusts a limited area and can make the set look worse--like having a cigarette lighter in your car--not really needed.Flash focus rarely if chips have been replaced will SAVE the adjustments.The set stores the convergence adjustments on a board inside--best way to adjust is with the Sony remote to enter the tech menu and adjust there--when done one of the numbered buttons is pressed and Save? in red appears--press same button again and it goes to green which means adjustments have been stored in the set.The tech menu will also always give a much better adjustment of the entire sceen.
