I have this same problem with my 52 inch toshiba regza , The repair shop has said the cost of repair is as much as it is to replace the TV. I am past the one year warranty, but less than 2 year ownership, so Toshiba won't fix the known issue. Solution is don't buy a Toshiba

set uses either two boards that drive each half of the screen or combined both into only one larger board---Google the actual model number with "parts" to see what parts are available---might bring up a list of boards for this set and prices, Toshiba boards are usually rather expensive from them.

start by checking the power supply in the set and if not able to do that consider taking it to a shop for an estimate.

US$ 3499 = 193 743.079 Indian rupees

Expect to be sorely disappointed, LCD panels cost nearly as much as replacement cost on the whole unit.You might try the link below where 'parted-out' components are sold.Jimmy's parts

Steven, based on your model number...you have a 52 inch tv, correct?

U tries check the power source and unplug,replug the tv back like about an hour later.For the tv to do a resetting itself back to the factory setting.No,fans in LCD or Plasma flat tvs.If this tv a LCD flat screen tv than the tv have power supply board problems,this tv doesn't have fan design into it.After it goes off the tv power LED light indication on the tv bazel frame are blinking?Yes that the tv have a power supply board can't sustance power voltages to the tv anymore.The tv power supply board that the board where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish power supply board for the replacement.Or have the tv service by a athorized LCD tvs and Plasma tvs shops.

Not likely, this TV (Toshiba 52HL167, http://www.amazon.com/Toshiba-REGZA-52HL167-52-Inch-1080p/dp/B000MY08GA) uses CCFL (Cold Cathode Fluorescent Lamp) for backlghts, most failures are due to bad power supply, bad DC filter caps, bad Backlights inverter board.
It will require in-depth troubleshooting.
If you decide to DIY repair, then you should read my guide first.

Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series. Please post back what you find.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck........
