No picture or sound. temperature indicator is on (blinking) tv was unpluged for 10 minutes. when i repowered it the problem remains. i suspect a temperature sensor is bad. i found a tokin ohd3-90m physically attached to the fan housing. how can i test this co
hitachi 50v500a projection lcd mponent? or what else might be the problem?
Did you ever get a answer to this question? I have a hitachi 50vs810 with the same problem. I found the same sensor "tokin ohd3-90m."
I ohmed across mine and it shows open. I then held my lighter under it and it stayed open. I suspect this part is bad so I tried jumping it out. No change. Still have the same blinking temp light.
So... in the end I don't know if I tested it right or not either. Good luck and let me know if you learned anything that can help me out.

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.
Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The
table in Figure 4-3 list the User Initialization procedures.
Note: Pressing INPUT and FORMAT is the same as
the Initialization in the Option Menu (MENU-2-4-7-0)

The front panel LEDs, refer to Figure 4-4, also assist in
determining the cause of a symptom. Figure 4-5 illustrates
normal LED operation. Figure 4-6 shows the
LEDs response when a problem is detected and indicates
the possible cause.

Most current designs of TVs would need a couple of hours unplugged before it would reset itself to default settings. There are some instances that overnight would be better.
If this proves to be not corrective, please post back with the brand and model of your TV.
Hope this be of initial help/idea. Pls post back how things turned up, details as requested or should you need additional information. It would also be of help if you can post any indicators such as blinking lights (LEDs) colors, their blinking sequence and anything else out of the ordinary.
<img src="mas_baz.jpg" /><br />There are three LED indicators. LAMP, TIMER, STANDBY/TEMP. Each Led or combination leds indicated problem.<br />
<li>LAMP blinking : The picture will automatically appear in about 15 seconds.</li>
<li>TIMER and STANDBY/TEMP blinking : A cooling fan inside the set is not operating normally.</li>
<li>LAMP and STANDBY/TEMP blinking : Lamp cover on the rear of the set is not properly shut.</li>
<li>STANDBY/TEMP blinking : Check if the ventilation hole on the rear of the set is blocked, because if the inner temperature is too high, the power will shut off.</li>
<li>All LED blinking : Lamp may be defective.<br /></li></ul>It takes about 30 seconds for the TV to warm up, so normal brightness may not appear immediately. The TV has a fan to keep the inside lamp from overheating. You'll occasionally hear it working.<br /><br /><br />
I would bet the illumination lamp has reached the end of it's life (~$40 online). Should be easy to replace. Also possible the ventilation vents need cleaning, which could cause the lamp to overheat and turn off.
These blinks of LEDs are fault indications. If you wish to get more details about these blinking codes, check this link. The details are there. It is very difficult to include all those details in tables here by this window.
The tv board that call the HYPER board nown as the tv convergence board was dying and have problems,but the tv was still used able that why u able to unplug it awhile,replug it back and get it up and running.Now the tv HYPER board known as tv convergence board are totally dead,colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures for a minute when the HYPER board was still functional for a little bit.Now the tv HYPER board getting no voltages at all,that why ur tv getting only a power LED indication light flashing only.The tv must get it tv HYPER board fixed also known as a tv convergence board.The tv HYPER boad must have it parts replace like 2 STK convergence ICS and some or all of it resistors too.To get the tv up and running again.The tvs shops will cost u like $300-350 for parts and labors.
Tv now,have a LED light indication "LAMP" on the frame are blinking or flashing.Metallic sound are clicking noises?Yes,sound like the board that call the Ballast board it is dead.This Ballast board only job are to ignite the tv projection lamp only.U have some mechanicals skills like take things aparts and putting it back together again?Yes,tries websites like Partstore.com,Ebay.com to buy a new Ballast board for the replacement.The tv projection lamp might have to be replacement change too,because,when the Ballast board has died and exploded the voltages and current high voltages could have more than the tv projection lamp now could take.
First thing, unplug the set and wait 10 minutes. Then plug it in and watch the green power LED. If it does nothing push the power button and watch the power LED. If the set doesn't respond hold down the MENU and INPUT buttons on the front of the set until the LED starts blinking. If it blinks at this time count the blinks and then repost.
Sony TV;s will give a service code, count the blinks, eg; 2-6, light will blink X amount of times, hesitate & blink again so many times. Count and report back but, I would recomend to unplug the TV's power cord, to reset the TV's system. Unplug for at least 3 minutes. I hope this was helpful.
