    Picture was out of focus when turned on this morning, when I went to menu to try to see if I could adjust it just turned off and won't come back on. Tried unplugging and replugging after an hour or so--still won't come on. Is it something I could fix myself? Don't want to pur too much into a ten year old set.

Turn tv on. green light solid display, no picture or sound


The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

Sound but no picture. I'm thinking I need a new picture tube but how much is it going to cost me?


First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.

No power Up , No Sound , No picture


Im sorry tom have to inform you that a red light blinking is an indication that the main power supply is good BUT the sweep supply has a problem .. Most likly the high voltage transformer as well as the horizontal transistor is bad. if you have no solid state repair experience, you will not be able to fix this set on your own as we techs do gfo to school to learn the circuits in these sets and there are safety issues you have to know and equipment you have to have. sorry my freind but you going to need to call or take the set top a trained tech to trouble shoot as you cannot look at the board and see a problem. you have to troubleshoot the board and test the circuitry.

TV just turned off by itself and wont turn on....


LCD type TV's ought to be the most reliable type, but these Polaroids all have early failures of the power supply. Only way to fix it is to replace the whole electronic module. Call Polaroid cust. service and be persistant because they are used to abuse from angry customers. Well, it is possible to replace the elec. caps in the power supply and maybe the FETs, but us experts are kinda keeping those details for the paying customers.
Good Luck

usually the high pitch noiese like this indicate some kind of power supply problem. The power supplies inside are called "switching power supplies" and if they're overloaded will make the kind of sound you describe. It sounds like there's a serious problem within. Probably should have it serviced.

If you had an older set, I'd say the flyback transformer has malfunctioned, but I don't think they're in todays set.

Let me know what happens... please rate accordingly.

Buzzing noise with no picture or sound.


The power supply is telling you that it has a short. I think you have a bad high voltage transformer in the horizontal deflection circuit. I've repaired several RCA's with this very same problem. The newer RCA's are vert prone to high voltage transformer failure ! Stargazer

Tv turns on but no picture or sound, power light blinking


How many blinks does the light do? Or is it constant?

No Picture No Sound


I think you have a short somewhere inyour set most likely the horizontal output transistor which may have shorted by the high voltage transformer going bad. The faint ticking sound that you hear is the power supply trying to start but the shorted load won't let it. Stargazer
