I have a Polariod 32in, Screen Flickers while on!

I'm a little confused here as without the 5 volt standby voltage the blue light won't come on, the TV will be dead like its not plugged in, are you sure you were on the right pin when you measured that? It almost sounds like your on the PSON or PWR-ON pin.

I believe you may be confusing this particular error reference to voltage with the power supply's (PSU) available rails (in that case, no there is no 24v rail).

Regardless, it is likely you merely have a faulty PSU. You have two options here as I see it: One, purchase a PSU tester and verify that your PSU is failing (you can get one of these for as little as $6), or you can simply replace the 4700's 450W power supply for as little as $20-$25. In my opinion, and that is all I can give with the available information, you are better off going with the latter. Chances are, you are not going to be running a whole lot of additional PSU tests in the future (and it sounds like your PSU is failing) so you would basically just be spending an additional $6 on a the new power supply that I am very confident you need.

Just think, with that saved six dollars... you can buy approximately 1.82 gallons of gas today!

If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

Remove power board. Using 2 12v car batteries hooked in series, temporarily apply 24v to the CN2 and CN3 connectors. If tv operates fine, then the power board needs to be rebuilt. If problem persists, then the power board is good and the main board has some bad capacitors on it.

there is 2 problems that makes this tv have standby fault.. so here they are,!

1.)main av board ---the 8 leg eeprom loses programing just under LVD CABLE TO SCREEN -£14.99 from a guy or if you can program yourself 4.99 for the flash to reprogram,.

2.)POWER SUPPLY FAULT IS MLT199TL PSU. (UA4)AREA, SG3525AN (16 leg) Regulating pulse width modulator.

the first fault all votage at psu will be there ,, 5v / 12v / 24v

the second fault psu will have 5v standby but no 12v or 24v this will stop the secondary from fireing up.. hope this helps.

your right there will be a bad caop in the power supply the can will have a domed or puffed top the value is printed on the side replace it and it will all set to go

It could be a low power problem on the computer. The first thing I would check is the PSU for the PC. Is it at least a 250W PSU.

change the lamps unit will work fine.

I would recomend replacing the 11 caps on the inverter as 90% of the time its failed capacitors on the inverter. If you shine a bright light into the screen can you see the pic? Thats usually one of the first things I do when I suspect bad caps on the inverter.

Hi, Please measure all windings again and see if there is one lower than 900ohm. All CCFL might seem working but only for one second before the protection circuit cuts in. By the way, there is something that I would like to know, what is the type number of your remote control?
