    Zenith C27C41T the TV looks like it had a problem with S-Video on front of TV that Shorted.

    R2925 Burnt as well as the Traces on Circuit board burnt off. back rca and s-video connection has burnt circuit board trace.

    right from the hot ps 155 is actual 163 seems like most voltages are 7 volts over. but then there are some that are under. is there a way to test c3213 to see if it is shorted.

    Replace shorted zener diode x3204 ? = ECG519

    Burnt resistor = 1K 1/2 watt

LG crt tv 21fs4rge-TS resistor R407 burnt i don't know the value


A burned out resistor means too much power has flowed and burned it out.
you need a schematic to find the resistor value but also what other parts have blown as I can guarantee just replacing the resistor would just mean another burned out resistor.

I see a box and Video 1 "behind" my picture


if you can see it at all times then yes it has been burnt into your screen. this may have happened if you were using some kind of electronic (game console) on the video 1 setting the tv may have also been left on that channel for a long period of time.

If you are trying to view TV channels, you might have to run a channel scan, check your user manual to see how to do a channel scan. Or just go into the menu and I'm sure it is there under channel setup or some name like that. I hope this helps you.

Why do my TV shuts down?


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Blue on the screen of the tv


Try to initialize it!

I had whole redish/pinkish screen on my 50v500 starting a few days ago, then I read through each of the threads on this site for the samilar problems on my model. I found TVtechmaniac's solution (pasted below) solved my problem. Thank you TVtechmaniac!

Enter the I2C Service Menu, be sure the power is OFF.
1. On the front control panel, press and hold the INPUT button.
2. Then press the POWER button for two seconds.
3. You may keep the INPUT button depressed until you see the OSD with the Service Menu displayed.
4. If you don't see the service menu, please repeat Process making sure you wait until the Power blinking LED stops.
5. Execute the Memory Initialize operation after the adjustment values have been written on a sheet of paper. Highlight "MEMORY INTI", arrow to the right and hold the button to the right (approx 5 sec.) until a check mark appears in the box. This activates the Memory Initialization.
6. After the Memory initialize operation has finished (10~15 sec, the channel will revert to CH 3.) the pink image symptom should be fixed.
7. Write back the adjustment values from your notes to their respective adjustment parameters in the adjustment mode. (In other words, set the Data Values back to the the Data values written down before the Memory Initialization procedure). NOTE: Make sure the SELECT Button is pressed on remote after every change to the values. Failure to do so will result in the data values not being changed.
8. Exit I2C menu. Press exit repeatedly until you go back to the normal picture.
9. Turn the set off-on and Confirm the picture remains in a good condition.
BE SURE TO COPY DOWN DATA SETTINGS BEFORE INITIALIZING I2C SETTINGS

Have a toshiba 27df47 flat screen tv. how do you


Hi there,
First make sure the video inputs are not locked using these instructions:
To set up the video lock:
1. Press MENU, then press or to display the LOCKS menu.
2. Press  or to display the password entering mode.
3. Use the Channel Number buttons (0-9) to enter your password,
then press ENTER. The LOCKS menu appears.
4. Press  or to highlight VIDEO LOCK.
5. Press or to select:
• OFF: Unlocks all video input sources.

Then it appears that choosing Video 2 using the TV/VIDEO button should enable the front input.

An entire manual is avialable here that should closely match your tv:

Resisters questions


Its best to replace both IC's. As far as the resistors, there are location #'s marked on the board where the resistors are mounted. If any look burnt, get the location numbers off the board, and your model # and email me @ halselectronics@comcast.net. I will get you the resistor values.

Problem with Samsung TV


SAMSUNG Convergence Problem


It looks like blue convergence. Look at menu, select convergence and see if blue top is bent down on convergence adjust screen. Probably won’t adjust.

Some Samsungs have convergence IC’s on a separate convergence board in the back of the TV. Others have the IC’s mounted on the main deflection board. Either way the board has to be removed to get at the dud IC’s and associated burnt resistors.

You remove the appropriate board, determine if any resistors are burnt or damaged, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's and re-install the board.

Now you have to adjust it to look like new.

If the unit has not been misadjusted and everything is OK now, running the auto focus may put the picture back to it’s previous stunning quality, as it was before IC failed.

If after self or autofocus it is still misadjusted noticeably, try the customer convergence adjustments. Operators’ manuals are available on web through searching.

If convergence can not be adjusted properly, you messed up chip install or resistors may be wrong value or open; or it needs major adjustment.

If you live around Calgary, Alberta try me instead:

http://calgaryconvergencerepair.weebly.com/convergence-explanation.html


Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.

Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.

Good Luck

Green screen


if it is "C514" it is capacitor. maybe the green section from the crt board is dead, try to test the transistor from its circuit or resolder it.
