Removed and checked the power supply unit and confirmed the capacitors
C905 220uF 420V was measured at 200uF
C926 22uF 160V measured at 21.6 uF
C908 10 uF 100V measured at 10.35 uF
C910 47 uF 63V measured at 45.8 uF
Resoldered all of the joints on this PCB to ensure good connections.
On the Main PCB checked capacitors
C401 220uF 35V measured 214 uF
C417 100uF 160V measured 100 uF
C411 3300uF 35V measured 3090 uF
D204 was still a diode
C430 4.7nF 1600V measured 4.5 nF
C406 4700uF 25V measured 4460 uF
Reassembled and confirmed worked OK

These checks / repairs did fix this fault and the television is running well.

SOURCE: Shuts Off Immediately

Does the TV shut off if a signal from the scart is selected? Philips sets have an annoying habit of going into standby after a very short time if there is no video for the synchronising circuits to lock onto. I find this a nuisance when I am searching for a signal from satelites when you move the dish. By quickly changing channels you are resetting the shut down circuit. This must be a time-out circuit controlled by a capacitor charging (I suspect) which has gone low in value, probably electrolytic. Replacing the capacitor should solve the problem.

it is due to plug or socket loose or sparking in that area. if it is ok then it is due to some component failure in power supply of tv. as per schematic is concern please go to. www.serviceinfo.com go in search & give model no.it is freely available.

The first thing in this unit is to check the ribbon cable that goes from the front control panel to the back ssb board, I would unplug and replug to make sure seated properly. Then try it again. There are alot of screws to take out but worth it if this solves the problem.

Once tv is turned on it stays on for about 2 min and shuts off. first the picture and the sound is still going then seconds later it shuts off and the lamp button blinks??/

Sounds like you have a problem that shuts down the Power Supply Unit, PSU, OR indeed more likely a faulty PSU.
In any event it is time for the repairman.

Projection TV keeps shutting down

Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

TEAC CT-M685

This is a vertical-deflection problem. Try to adjust the vertical (height and linearity and hold) controls, which should be screwdriver potentiometer controls on the back of the set.

If this does not work, a defective component in the vertical-deflection circuit will need to be repaired.

I hope this helped you. :)
