I also had blown capacitors on my power supply. You can see when they're bad: the tops split or bubble up like a dome. I changed most of the caps, just to be sure, and it fixed the problem. Careful of the larger capacitors. They stay powered for some time and can shock you pretty badly. Good Luck

hi the blue and red cycling is a bad mainboard firmware fault thanks shaun

Replace power supply board from PTS. No parts available for PCB.
Generic part nr for IC3 is A6252M can't find one easily.

Are you talking monitor rather than tv? I have an LG 22 inch monitor and the on off button is on the bottom, If I don't hit it right or just tap it, it won't turn off but flashes. Where do you have it plugged in? Is it with some other electronics, or right to the wall outlet? I'm really at a loss as to what your problem really is. Are you using the remote? One quick fix might be the battery's in the remote. If they don't have enough power, short or no signal will be sent to tv or not being able to decipher it.

REINSTALL ADAPTER IN THE DEVICE MANAGER SETTINGS. REMOVE THE ADAPTER AND RESTART COMPUTER IT WILL AUTOMATICALLY REINSTALL YOUR ADAPTER.

There is no other way to select the input, without a remote control.

Actually it sounds like your component cables need to be changed. If you are connecting with component cables please try another set (if you buy a new set like from Radio Shack make sure you can get a refund if that is not the problem and you need to return them).

It could be any number of things. Try to use systematic diagnostics to trace where the fault lies. Start at input end of system to find out which bits work and which don't.

1. Do you get a picture using a video recorder, dvd player, gaming console? If yes the problem is with your tv signal.
2. Connect a different tv to your antenna / satelite dish /- can you get an analogue picture? If no the antenna (aerial) may be faulty
3. Does the satelite receiver / digital terrestrial (e.g Freeview) receiver give you a picture on a different tv? If yes it could be either a technical fault with your tv or it needs retuning to the correct stations (enter setup menu and reinstall stations as per user instruction manual)

U check the power supply board and it is good and power is on LED light power indication light up.Than only one possibility the tv Tuner signal board is shorted and dead.That the board,where the incomming broadcasting signal cable plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner signal board for the replacement.

It may have dying 24vdc power supply due to bad caps, check that first, it may cause more damage if you keep turning on and off.

Power supply module is to supply voltages to the main control board (the board where the TV cable and video cables are connected to), backlight inverter board. You can buy the whole control box which has both board assembly (power supply and the main control board): http://www.shopjimmy.com/catalogsearch/result/index/?q=Polaroid+4011-TLXB+&limit=25

Does it work in TV mode?
It can be either the power supply is not putting out all the needed voltages, right now you only have the 5vdc standby voltage (because the RED lifght is on) or the backlight inverter board is bad, it is the board that drives the CCF lamps which is the light source for the screen, it may be bad or not getting the 24vdc from the power supply. worst case will be the main board that is not sending signals to turn on the power supply and the backlight inverter board.

is your main antenna / cable (or cable box) connected to tv/monitor cable in...the monitor is on Ch 3...do you have dvd player or vcr...these devices must be set to cable / ch 3 also...and hook up to aux 1 or tv 2 depending on the jacks avail on the back of tv (please note if you are using a dvd recorder premium ch like HBO is and will be scramble)

Look at the power supply first; look for burnt parts, bad capacitors, etc.

Turn it off and leave it off. It seems that your unit has some sort of major PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.
