SOURCE: Power button flashing red, cannot turn on or off...

this symptom is usually caused by a breakdown in the power-supply circuit. in most modern receivers (transistorised and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (horizontal oscillator, pre-drive or drive circuits.). this is because the supply volatages for the tuner, video intermidiate frequency(VIF), video amplifier, sound intermediate frequency(SIF) and vertical output circuit are usually supplied by the horizontal output circuit. since you are not inclined with this kind of job, better bring it to a qualified tv technician. with regards to the cost of repair, i cannot tell you the price since my location is different from yours. but to give you and idea, here in philippines $100 is enough for this kind of trouble!

SOURCE: TV is not powering up and red light keeps flashing

I had the same red blinking led problem on my Toshiba Theaterview tv. I resolved by:
- Unplugging the tv.
- Press several times (3 or 4 times) the tv Power button.
- Plug the tv back in and press the Power button once to turn the tv on....tv worked!!!

I've had the problem before and tried unplugging the tv for a couple of days and that had also worked, but I this recent solution seems to be faster.
Good luck!

SOURCE: Red Blinking Light

These types of problems are allways hard to diagnose.. If you were to power on the set and preform tests, you would think that everything was fine until the moment it shuts off.

Look on the main power board and see if you cant find the thyristor (thermal switch), those are the things that when heated will cause the set to power off for safety reasons.. They are normally placed where ever a large heatsink is. That may give you a location as to the problem and you can put a meter around its 2 pins with the set off and unplugged a couple of min after failure, if its short (0 ohms) thats not the problem, if its open, it triggered the event.

Second, you can run the set for a while and check the voltages and Ve, Va, VCC, Vsetup etc and compair to the markings on the plasma PDP sticker. If you see one is falling down over time (volts will be lost as heat) then you can isolate that portion of the supply.

Third and allways the best way to go about these problems is buy a thermal gun and moniter various spots for heat.

Its just vary hard to say, resistance could be off somewhere, diodes could be overheating as well as fets and caps. Thats why a good thermal gun can point you to exactly where the problem is.

Hope this info helps, but I would suspect the problem is on the main power supply itself and not the y sus and z sus boards side boards.

SOURCE: toshiba TP43H95 projection tv has power but no picture

If it shuts off and then the power light starts blinking red or it never comes on but the power light just blinks red continuously that is usually indicative of the convergence ICs (STK 392-110). You never want to replace the ICs without also replacing the resistors that are associated with them. There are usually 6 resistors, one for each of the colors and there corresponding direction, IE Red horizontal, red vertical, blue horizontal, ect. In the case of this model tv all of the resistors are 2.2 Ohm and 2watts. You will find them right where the STK 392-110 ICs are. Right in front of them. They are blue and have this color code on them. Red, red, gold, gold. These are represented by stripes on the resistors. You can get the parts from www.bdent.com They carry the ICs and the resistors. If you do not feel comfortable completing this repair I could do it for you if you send me the board. My email address is: missionelectronics@sbcglobal.net The cost is 375.00 and that includes parts.
Good Luck.

My digital tv is saying no singal whats the problem and how do I fix it? we have a huge antenna on our roof







1 – Is the NO SIGNAL issue happening on just one TV?
CORRECT INPUT or SOURCE
If it is just one TV that is showing the NO SIGNAL…
-Be sure your TV is on the correct source or input as your CABLE or SAT BOX.
-Press the TV button on TV remote control to turn your TV ON.
-Press the INPUT button on your TV remote control.
-Cycle through all the inputs on your TV.
-Do this until you are on the INPUT your CABLE or SAT BOX is plugged into.
-You should then see the CABLE or SAT programming show on your TV.
HINT: Your TV will most likely list the TV INPUTS as: HDMI 1, HDMI 2, HDMI 3, VGA, Component 1, Component 2, and so on.
If you still see NO SIGNAL on your TV screen, see the next step below…

2 – If you have your TV on the correct INPUT or SOURCE and you still see NO SIGNAL…
CABLE OR SAT BOX NEEDS RESET
-Remove or unplug the power cable from the Cable TV or SAT set top box.
-Keep it unplugged for 2 to 3 minutes.
-Plug the power cable back into your Cable or SAT set top box.
-Give it some time for the Cable or SAT box to power up, get the signal, and initialize.
If you still see NO SIGNAL on your TV screen, see the next step below…

3 – If you have reset the Cable or SAT box and still have the NO SIGNAL…
UNPLUG THE CABLE GOING FROM THE TV TO YOUR CABLE OR SAT BOX
-Remove the HDMI cable or other cables from your Cable TV or SAT set top box.
-Keep the cable unplugged for 2 to 3 minutes.
-Plug the HDMI cable or other cables back in.
-Give it some time for the Cable or SAT box to get the signal and initialize.
HINT: Make sure all the cables that are connected to your Cable or SAT box and your TV are tight, undamaged, and secured.

4 – If all of your TVs are affected with the NO SIGNAL screen…
BE SURE THE COAX CABLES OR ETHERNET CABLES ARE SECURE or CABLE OR SAT IS DOWN TEMPORARILY
-Be sure to check the ones where the CABLE or SAT come into your home.
-Be sure ALL Ethernet and Coax cables are secure.
-Call your CABLE or SAT provider to see if there is an outage.
-Realign your Dish if you have SATELLITE.

What's your problem? won't turn on..... yellow/orange light continually flashes three times...


Toshiba Regza 37in - 37HL17
TV will not turn on - Yellow power ind. Light blinks three times...
Fixed with a firmware update (hard to believe, but true). Search Google for a file named: 2007SEN069.zip (don't worry if the page you find it on doesn't mention the 37HL17 - it worked fine). Unzip the file, and copy the 3 folders and 3 files to the root of a small SD card. The SD card MUST be 2GB or less in size (I used a 1GB card), and it MUST be formatted with FAT-16 (not FAT-32). Mine was pre-formatted as FAT (FAT-16). The SD port is on the back of the TV behind a cover plate near the power cable. You do NOT need to remove the back cover of the TV, just the small cover plate (1 screw). UNPLUG the TV; remove the cover plate; insert the SD card (prepped as explained above); Plug in the TV; Watch the yellow lights blink, then turn blue, then go dark; UNPLUG the TV; remove the SD Card and replace the cover; Plug in the TV; Yellow lights will blink a few times (this is normal); when blinking stops, turn on the TV and you should be good to go. :-)

Red vertical line on the screen due to external shock


This is most likely caused by the cable on the T-CON board being bent out of place by the shock.
If you know how to work on electronics or have a friend with knowledge/skill you can fix it.

DO THIS ONLY IF YOU KNOW HOW TO WORK WITH ELECTRONIC EQUIPMENT.

REMOVE THE PLUG FROM THE WALL. REMOVE INPUT signal cable from set.
REMOVE THE POWER CABLE FROM THE SET.
>Lay the set down on a flat cloth covered surface.
>Remove the back cover.
>Remove the shield covering T-CON board. This small board is located in the center near the top.
>Move the cable(s) connected to the T-CON around.
> Set the tv upright and make sure it is stable.

DO NOT TOUCH ANYTHING ON THE BACK
.
ATTACH INPUT SIGNAL cable to set.
ATTACH THE POWER CORD TO THE SET.
PLUG THE POWER CORD INTO THE WALL.
>Use the remote to turn the set on. If the vertical lines are gone, THEN TURN the set OFF.
REMOVE THE PLUG FROM THE WALL.
REMOVE THE POWER CORD FROM THE SET. Remove signal cable.
> Lay tv back down on table.
CAREFULLY REPLACE THE SHIELD over the T-CON.

Replace the back cover etc.
Now you can reconnect the input cable and power cord.
SOMETIMES THE IMAGES can get worst and you have to repeat moving the cable around. In the worst case you can dis-connect and re-connect the flat cable WITH THE SET UNPLUGGED.

I believe the T-CON may sometimes be called LVDS and look similar to;

Wont turn on but yellow light is flashing


I followed the steps at the following link and it worked for me. I have a 2007 Toshiba Regza 42HL67, but the firmware applies to many models as documented in the readme file at the location found via the link below. I used a 1gb SD card formatted FAT16, copied the unzipped files and folder to the card (wasn't sure if it required the top level folder or only the files under the top level folder so I copied both to the root of the SD card), unplugged the TV, inserted the card, plugged in the TV, waited 2.5 minutes, unplugged the TV, removed the card, plugged in the TV, yellow light flashed 3 times and went out. I turned on the TV and it has worked normally since last night.

Toshiba 50hp95 will not respond and has flashing red power light. It seems many people have this problem, what's the solution? We have tried all the Toshiba suggestions.


My 50hp95 had the same problem; the red power light is flashing and the tv will not turn on. I unplug the power and plug it back in and the TV clicks, but the power light continues to flash red. My problem was a bad Seine module which you can bypass if you do not need to watch HD off air programming. Since I get my HD from the cable, I can bypass it. All you need to do is remove the back panel from the TV (unplug the TV first) and on the main circuit board unplug the white connector labeled PJ63A. The main circuit board is the one in the center of the TV and the PJ63A connector is the bottom white connector on the left side of the main circuit board (the label is printed in white on the circuit board under the connector). Once I plugged the TV back in it worked immediately.

Watching tv when the picture went black and now the green on light flashes for 30 times and turns off


A green flashing light for this model of TV indicates that the lamp cover is open on the TV.
  1. Unplug the power cable to the TV.
  2. Remove the 2 retaining screws on the lamp cover with a Phillips type screwdriver.
  3. Remove the lamp door completely from the TV.
  4. Remove the two retaining screws on the lamp case.
  5. Lift up the fixed wire handle of the lamp.
  6. Pull out the handle slowly and remove the lamp case.
  7. Insert the new lamp gently into the correct position. Make sure it is inserted correctly.
  8. Using a manual Phillips screwdriver (Do Not use an electric screwdiver), tighten the screws you removed in
    step 3.
  9. Replace the lamp cover and tighten the cover screws.
  10. Plug in the power cord and turn on the TV. After the initial warmup period (which may take up to several
    seconds for full picture brightness), the TV should operate normally.
If any of the following conditions exist, turn off the TV, unplug the power cord, and repeat steps 1–9 to ensure that the lamp unit and lamp unit
door are installed correctly:
  • The lamp indicator flashes green.
  • No picture
  • Dark picture
  • TV will not turn on
If, after repeating steps 1–10, the problem still exists, call Customer Service at 1-800-631-3811.

Brand New printer status led RED, Smart Panel error "dev home"


Samsung CLP-315 Dev Home error
It appears that the Dev. Home error is very common for Samsung printers. It obviously has different reasons. In my case I solved it by stabilizing the deviation clutch. It was too unsteady and the dev. sensor recognized a fault.
The dev. clutch is situated under the right cover, which is the power supply side of the printer. To remove this cover you need to firstly remove the top cover, which is held by two screws on the front. Then uncover the right side by unscrewing one screw on the back, near the power supply inlet and unclip a couple clips on the top side of the cover. After removing it you have to find the deviation electrical clutch. Check if it is too unsteady. If it easily moves, you need to somehow stabilize it, in my case by a couple of leather straps under it, so that they press it up and make it steady: 5_19_2012_1_08_58_pm.jpg

After that simply check if you have stabilized it properly. If you have the green light must turn on after switching the device on.

NB! Be extremely careful when power is ON, because there is high voltage running. I'd suggest that you would stabilize the thing with non metallic item to keep safe. Good luck!
