I made an easy tutorial for the cap problem. If you are not comfortable doing the work yourself other people have had Radio Shack do the it (very cheap and without shipping).
I feel that we are all in the same situation, if we had the money to get it fixed professionaly we wouldn't be on the internet searching out a solution.

It seems that the manufacturer of the Polaroid FLM-373b and other models of HDTV either used the wrong parts or there is a design problem. I found someone on the internet who said they replaced two capacitors on the power board and it started working just fine. I took the power board out of mine and sure enough the two caps with the 10v markings were swelled. I replaced them with two 25v caps and it is working just fine. All the other caps on the power board were 16v and above. So, I would assume they were shipped the wrong parts or they just put the wrong caps in to begin with. If you want to send me your power board I will fix it for $50.00 plus shipping.

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician.

rpwest51, Monitor internal "switch-mode-power-supply could be in what is known as "shutdown immediate" mode having sensed (detected) a fault condition with itself or the inverter lamp high voltage supply. You or qualified technician will need to investigate unit to determine root cause down to component level and decide if unit is viable candidate for cheap DIY ($8 parts cost) fix. Above all else, remember this! Your "cold-cathode-fluorescent-lamp" back-lit LCD monitor is no different than any other brand in it's basic design and operation. If you do your research you will also have a good idea as to how those new style curlie-Q energy efficient screw-in CFL ight bulbs work.Read through my higher numbered fixya profile pages and those of other CCFL lcd monitor techs profiles and follow the links you find there for all options that you may have. Hope this helps. 12fixlouie
Your TV problem on power supply,some of components are damage.Such as power transistor,or diode or micro fuse.If you are a technician you check it or not you go to a service center they solve your problem by simple coast.
Have you ssen the back light lit up? If not, the power supply may have problem. If it has back light, then the suspection are the main board, T-con and inverter. Those boards need checked to find out exact defective board.
same problem this fixed it right away I was suprised

you have windows set to do automatic updates, you most likely had a
windows update installed that caused this conflict with Win Media
Player 11. No fix has been posted by Microsoft yet, so the only
workaround is to Uninstall/Rollback Windows Media Player 11. Goto
<Control Panel<Add/Remove Programs and remove Windows Media
Player 11. Follow prompts, restart computer when prompted to. Also
uninstall Windows Media Player 11 Runtime application following same
This will roll your Windows Media Player back to version 10 or 9,
whichever you had installed prior to version 11. You will need to
re-configure Windows Media Player again.
Your Zen should now be recognized by WMP and Creative software. You
probably need to upgrade your firmware at this point, follow the
instructions on upgrading your firmware, and you should be good to go.
This is a windows problem, not a creative problem. Dont blame Creative
for the screwed up hotfixes that Microsoft puts out on a regular basi
Did the service tech actually look at the computer? I don't know how anyone could make this diagnosis without doing some testing. It could be the motherboard but it could be something else too. I would first suspect the power supply. They frequently go bad. Test that.
The tech is correct about the internal short inside the blue CRT. There is a way to remove that short by applying a small amount of current to burn the short but that might damage the CRT even more. At this point the CRT needs to be replace.
I will post the instructions on how to remove that short but you will need to have a good regulated power supply and limit the amount of current to 1 to 2 amps.
The light does indicat that there is power to the sety but that doesnt mean that the power supplys working . Theres nothing uyou can do unless your a trained tech. The set should still have a parts warranty. Good Luck
