SOURCE: Sony KDF-E55A20 55 in. LCD... Problem red light flashes 5 times

A 5 blink error indicates a bad lamp driver. However a lamp may possibly cause this too. I suggest putting a new lamp in if you have one just to verify the lamp is not the problem. If it still fails with a new lamp then the lamp driver is the problem. This part should be replaced by a Sony authorized servicer. The lamp can be replaced easily by you. The lamp replacement instructions are in the TV's owners manual. Good Luck

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.

My Samsung TV won't turn on


Please describe the problem more accurately. Flashing red usually means 'stand-by' state, flashing blue/green - starting up. When (during that) do you have a sound? Are there any 'high voltage' sounds like soft screeching from the screen? Is it LCD or LED?

Hi there. I have a 42" Matsui M42LW508 LCD TV.


probably there's a lose solder in the power supply board of your lcd,
and maybe from inverter board. these two parts of lcd consumes much power and heat.
so once you use it can produce heat that can affect the solders under the board.
the same with inverter board.
if you know how to disassemble or some technical knowledge you can re-solder it by using soldering iron and lead.
but if you not capable, go to repairman and let him do the work.
it has to be repair before it can affect other parts of lcd.
thanks.......

The tv will turn on but no the screen wont. and


Replace the lamp would be the first thing to try. Lamp door switch on this model is notorious for going bad. If you replace lamp and still won't turn on jumper door switch. If you take off back you can see switch board.

When I turn on the unit I get a green light, but after about 5 seconds it switches to red blinking and I do not get a screen


What is the model of TV?

The Red blinking light is a Protection Error Code. Your Tv needs repair. Most common is the power or Main Unit / Logic Board.

Post your model and how many times the light blinks. Also try unplugging for about 20 min and see if it will turn on.

Some models you get lucky and its a common problum which makes for an easier diagnosis.
