Re: Flashing red light
Joechillin, how much TV repair experience do you have and do you own a mutimeter as well as an osilliscope? Ok first thing your going to need to do is to get a schemtic diagram. Find out with the scope, if the horizontal drive pulse is there when you turn on the set. If it is not then go back to the SMPS and check that. If it is, check the drive all the way up to the horizontal output transistor. If it is good up to there, and still no sweep power supply? Your going to most likly need to replace the flyback transformer and the horizontal output transistor and go from there. If you are there with this, great. But really man if you have no TV repair experience, we cannot teach you how to, as there are alot of factors involved. There is also alot of High Voltage inside these sets when the plug is even out of the wall. Also everything inside these sets is mounted or soldered on a printed circuit board. This set is a solid state TV and there are NO user replaceable parts inside. My friend, I would Highly recommend that you call in a trained service person to assist you with this repair. Good Luck

Check ur tv fan,if ur cooling fan are runnig,before all these LED lights are flashing.If not that ur tv problems.All these LED lights are flashing the tv making alots of clinking noises too like it trying turn itself on?Yes,than the tv board that called the Ballast board it is dead too,must be replace also.This tv Ballast board only job are to help to ignite the tv projection lamp only and keeping it on and running.
A continuous flashing red light with the word LAMP on it would definitely mean you're going to need to spend a few bucks on a new lamp....or for a few more, upgrade to a TV from this century that doesn't require lamp changes :)
the green is the reboot process and is normal. the red light is an error code indicator. count the blinks of the red light...it cant be 30 times (I think) it will blink a sequence, pause, then do it again for a total of three times. count carefully, it gives you three chances to catch the number it is blinking.
My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?
Solved by resoldering some solder joints!!!!!!!
Toshiba Model 57H81 Rear Projection TV - Purchased 11-09-2001
Problem: Toshiba 57H81 Flashing Red Power Light, No Picture/Sound, Blown Fuses F850 + F852
Symptoms January, 2009:
Upon turning on set I got flashing red power light and nothing else.
Removing plug for one minute and plugging in results in:
Audible click, steady red power light for 2 seconds then slow flashing red light
Pushing power button results in steady red for about 2 seconds then slow flashing red light, no other set activity
Removing power cord for several hours and plugging back in made no change
Audible click, steady red for about 2 seconds then slow flashing red light
Possible related note:Over past several months occasionally the entire screen would flicker momentarily and at other times be problem free for weeks.
Fuses F850 and F852 found blown
PD0074 DEF/CON Power Board
There are two main power supply capacitors in this set.They are C-809 and C-810.One their negative lead on the printed circuit board re-soldered leads and nearby contacts. I’m told that because the factory left out a printed circuit board eyelet, the connection will come loose over time.When I called Toshiba customer service they said there was a known solder joint problem causing blinking red light.
Replaced blown fuses F850 and F852.
I actually installed a fuse panel on the inside of the cabinet and routed the fuse connections here instead of ordering the special fuses and replacing them on the circuit board.
Had to use a 5 Amp SLO-BLOW for F850. Fast blow does not survive power up. Get the red blinking light.
Twelve hours of my time over three days to research issue, disassemble set, make repairs, add fuse panel.
Already owned Service Manual and Circuit diagrams from a different 2004 repair.
Less than ten dollars at Radio Shack for fuses and fuse panel. Already had wires, etc.
Some solder. Already owned de-soldering tools, etc.
Visited both local authorized Toshiba factory service repair facilities.One said repair would have to include replacing Q751 + Q752 STK392-110 Convergence Amps with ST392-180, and realigning set for a total of $500+ and it would be more if they had to order a power board. NO THANK YOU!Other shop said $65 for site visit and $30 to make an estimate that could be applied to repair.
The green power light is continually flashing and the tv will not turn on. I hit the reset button and nothing happened. I have exhausted all other troubleshooting methods. Please help, what should I do?
ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN. PRIDAH
Face it....your big screen is a Flasher.
but read back,,, I think you asked this before...go back about 1 or 2 months and see my solution to this exact problem.
but bottom line..you need a tech.
