To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main digital board.

Hello. I have a Polaroid tv that I bought on 2009. When I turn it on, there is s slight buzzing sound. After about 5 seconds the picture goes out and the screen is black, but I can still hear the audio of the show. The buzzing sound is still there also. Last night the screen was all different colors and buzzing. I had to unplug the tv and it was fine, but today the picture is gone. Please help! Thank you!
Please unplug the TV from the power.
Wht has happened is there are two parts in the TV that take the AC power from the wall plug, and convert that AC or Alternating (polarity) Current of electricity and convert it to a Directional (one Way) current inside the device called a power supply or PSU.
There are three major components to the TV, the TV Receiver portion where the radio signals are decoded, the Audio Section where the sound is amplified to a speaker, and a VIDEO section where the picture is generated from the radio information sent by the AERIAL or Co-AX cable hookup (or HDMI for Direct input).
Either way, there is no VIDEO where the picture is decoded and displayed on the screen.
You need to check the Connector Cable if it is a HDMI TV source you are watching , or it is the VIDEO section of the TV that has failed.
Usually the decoder are very robust, but the POWER CAPACITORS are what fail and no longer filter the Recified power from the power cord.
For this reason you heard the HUM, as the filters stopped doing what they were supposed to do.
Do NOT OPERATE The set any further as that will cause more damage. Get it to someplace that will fix tvs.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" of your device; that you want set-up code, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Soudbar come on after turning it off its a polaroid tb301 any help please.
Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go.
http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.
