My flat screen Sylvania TV is flashing different colors what's wrong


Better late than never. The problem is that your TV is in the service mode. There are many ways this can happen. But, lets just get down to fixin this! With the original remote and the TV on. If the TV will not shut off, do this. Press the left cursor button on the remote, followed with pressing the right cursor. Power off the TV with remote, or press off button on TV.

Secondly, your TV will power on and off. But you have flashing colors. Do this. With the original remote and TV on. Press the up cursor button, on the remote, followed with pressing the down cursor. Power off TV with remote, or press off power of TV. Thanks for asking me, Matt of Martins TV Repair.

Television stuck on black philips screen will not do anything except flash off and back on to same black philips screen.


Sounds like the media/main board is going out. You can change those out really easy with just a screw driver.
Check ebay with your part number off the board. Start with you tv model number and the the BOARD part number. Alot of board look alike but there aren't.
Also..
shopjimmy.com is a good place.
Good Luck.

Try to disconnect the set and a box if being used from power for a while and then power both back as either could cause this problem.

HI,
It's impossible to turn the camera off. Only way is take out the battery.
No button warks, but I can change the shooting mode and turn playback, but I can't change the image in playback mode.
Please, help me to solve this problem.
I think, the camera needs to be restarted, but how to do that?
Thanks a lot.

Blue crt assmbly maybe?


its very possible that the blue CRT is horting the set out. Heres how you can test it. Remove the speaker grille and access panel behind the grille and you will see the crts. remove the blue crt circuit board from the end of the blue crt and make sure it isnt touching anything then try powering up the set if it doesnt shut down then you have found the problem and you will need a new crt. or you can switch the blue circuit with the green and try it iwth the blue on green and the green on the blue then if the screen turns green before shutting down you will know that its a problem in the blue drive circuit and not the crt. lety me know if you need further assistance.

TV Problem with shutting off by itself


Mine just did the same thing.  Except for it was green instead of blue.  The service manual states 8 flashes from the light stands for an overvoltage.  After reading the manual for a bit I realized the bottom row of 3 adjuster screws from behind the speaker grill adjust the output for the red, green, and blue colors.  BEFORE OPENING ANY TV OR MONITOR PLEASE KNOW THAT THE VOLTAGE INSIDE CAN KILL YOU EVEN IF UN-PLUGGED so please be careful and only adjust what is mentioned here.  I un-plugged the tv, removed the grill and the board covering the internals, and carefully turned the 3 adjustment screws all the way down.  I then waited about 10 minutes (don't know if this made a difference).  I turned on the tv, turned the channel to an auxilary input (for a black screen), and slowly raised each of the 3 bottom screws one by one up clockwise until i could see a faint green, blue, or red line (depending on the screw), and then turned each one back a hair until the screen was black again.  Only adjust one at a time, the order for colors are blue, green, then red from the left.  I hope this fixes your problems.  Be careful when working inside a tv,  I suggest not using a screw driver to adjust the screws due to the possibility of it slipping and someone getting hurt.

Mitsubishi black diamond tv


Might be a bad CRT or bad video output IC that drives the CRT that would cause this issue.
