I have seen very similar problems for other tvs on here, but none really for mine. I turn main power on, get red light. Hit the power on the remote or the standby button, green light comes on. I hear a click and the crts powering. I get a red light on the power supply board. Then it all powers down and back to red light. I can't turn it back on with the stby button/remote. I have to kill Main power then start again.
I am assuming it is shutting down for over current conditions, but I really don't know how to go about isolating things to figure out what part to change. The four fuses I found on the power supply assembly were good.

No picture or do u have a blue (or some other color) screen? And the blinking red light, is that the indicator light down by the power button that is blinking? I have the same tv and very similar problem, i have a blue screen and the red indicator light is blinking. If you have gotten ur problem fixed I would love to know how, or vise versa if I get mine fixed.
Hi, Symptom shows that Mani Board is bad in your TLX-03210B Polaroid TV and need to be replaced. I do not see problem of capacitors in power supply board. Problem seems in system control section of TV that is located on main board. Click Shop Jimmy as it is best source to obtain boards of LCD TVs. Please call Shop Jimmy for main board availability as currently its out of stock.

this might be a tube leak check for fluid on the necks of the tubes with your hand. if none you might have a faulty protect chip- common-
forgot the exact location but it's on the main board, it's a 16 pin chip as i remember and it is a quad op amp. if you hold your finger across the pins underside it will turn on and stay on as long as your finger is there, if so replace the chip
I had a similar problem. Look for a burned/shorted out capacitor on the main board. (It is marked J-something I forgot), 10mm diameter ceramic capacitor, 1000pF 20k SON116175400 It is about 3-4" from the left edge of the main board (power supply side), near the middle of the board. It is close to a large transistor mounted vertically on a cooling plate. It is a special high-voltage capacitor, you can find it online. Check the large transistor - it may be damaged too (mine was ok). After installing the new capacitor I got good sound and really weak picture. I called a repair guy who found a bad chip - after 3 hours of looking. The TV works fine ever since. As I learned, in most cases all you need is a new $5 capacitor. If you had a good picture before, it is worth the "investment" to fix this problem.
Looks like the blue crt is bad and may have killed the main power board that has the high voltage supply.
A new crt is almost $400 and my distributer shows the power supply as
no longer available, but may be able to get it somewhere
else. Plus you need the service manual to realign and
converge everything (hope you didn't mess this up too bad).
Really need to find a good rear projection tech to do all this, but may
not be worth it.
