Tv w/ "loose magnifier"

Hello,

I am going to purchase this tv but the seller it has the following problem:

"This TV functions fine, but does not have the blue lighting working properly because the blue magnifier lens came loose. If this lens is repaired, then the TV would work perfectly."

Is this something that is easily/inexpensively fixable? If so, how can this be fixed?

    On the ad for the tv there's a picture of the guy holding the lense and a picture of the inside of the tv. Here's a link.

    Do you think that's the issue?
    How hard is it to replace a tube?

The coolant thickens over time causing an out of focus blue. 3 gun projectors are a technology of the past. Don't waste any money on this. You'll be miserable and continuously harassed by some problem or the other. Not worth it even if he's giving it away free.

If the lens came loose the CRT would leak its coolant all over the chassis. Sounds as if the Blue CRT may have a short and thats why its not working. If thats the case your looking at about 300.00 for a replacement tube if you install it about 600 if a shop does it.

    Its not that hard to change a tube but the cost factor of the tube If the set was free it may be worth it, but if the coolant got onto the chassis you will have problems as the coolant is corrosive and can end up deestroying the circuit traces and components.

Need tv code, tv is locked


Hello,

Turn on the TV and grab the remote. In most cases, you will need the original remote to unlock the TV if you aren't sure of the unlock code. If you don't have the original remote, you will need to purchase one.
2
Look at the screen. If you see a blank screen with a red key on the bottom of the screen, press 'Function' and 'Mute' at the same time. This should unlock the channel. This is an option for people who want the TV to stay locked but, want to be able to bypass the lock to watch a certain show or channel. All other channels will remain locked and the TV will fully lock when it is turned off.
3
Unlock all of the channels on the TV by entering the factory reset code. There are three main reset codes that TV manufacturers set. These are 0711, 6688 and 3308. Try each one until you find the one that works. This will reset the TV to original factory settings. When you do this, you will loose any information that you have stored in the TV, such as favorite channels, automatic timers and the clock. You will have to go through the full initial set up.
4
Call the technical support service number in your owner's manual if none of those codes work. A technician can help you troubleshoot the television because the problem may not be the locking control. When you call, make sure that you have the model number and serial number of the TV.
5
Take your television to a TV repair shop. In some cases, a professional who access to wiring diagrams for your television set may have to rewire certain components in order for the television to unlock. This is usually the case when the TV locks by itself while it is on.

Also note that forgotten the passcode of your Mitsubishi TV. You can make it alive without knowing the passcode. Please follow
V_Chip lock bypassing prodedure is as follows
You can view your locked TV, cancel the lock, or enter the V_chip lock menus.

This is done by pressing the number "9" and "QV" buttons on the remote TV control at the same time, when your passcode is requested. This process temporarily unlocks the TV.
When entering the V_Chip lock menu, this process deletes your old passcode and prompts you to enter a new passcode.


I hope this will help to solve the problem...

There is only a loosed or cold solder in the main pcb of your tv in order to fix this you should have a soldering iron, lead, and desoldering pump.Try to remove the back cover of your tv but be sure to unplug the unit before opening it, then try to pull out the mainboard of your tv but be carefull because some of the connector may accidentally remove and observe the solder part of the pcb, using a magnifying glass is much beter to locate the loosed solder.But when doing some soldering in the pcb be sure not to solder separate pin if accidentaly conneted it may cause much problm to the unit or you can try to contact a service technician to do it for and save from stress good day and best regard.

When I input s-video cable into RCA tv, the screen shows just black & white color, not full color that used to show. I tried to connect my laptop and dvd player with new s-video cable, but it didn't...


Take a flashlight and magnifying glass and look at the S-Video connector on the back of the TV. Check to see that there aren't any pins or other debris stuck in the four holes.

One pair of holes is for the brightness (luma) signal, which gives you the black and white picture, and the other pair of holes is for the color (chroma) signal, which seems to not be functioning.

If there's nothing in the holes, then the internal connection may be flakey. Try gently wiggling the plug on the TV side and see if color returns, even briefly.

Does your TV have other inputs like component YPbPr?

The TV is not a plasma, it is an LCD. Send it back to the seller ASAP. His add is misleading and deceptive. LCD TV`s are back lit with fluorescent lamps. They are powered by ballast transformers usually located on the inverter board. My guess is that parts are not available that's why he is dumping the set. Stick with name brand Japaneese products only and stay away from no named made in China junk. Hope you get your money back. Good luck!

T.V. COMES ON FOR 10 - 20 MINUTES THEN GOES OFF


well based on your story it seems that your tv when get hot loose some of its contact. i beleive the symptom is cause by a loose solder (cold solder). this is normal especially tv's that are aging. it tends to loose its contact because most of the parts/components of this device are becoming hot when being operated. example of this are resistors, transistors, and ic's(integrated circuits). check the power supply circuits and the horizontal deflection circuits. because these two circuits are responsible for problem you are experiencing. also use a magnifying glass in inspecting the board. based on my experience looking alone without this glass is not enough. you need to magnify it, to see it clearly. but if you are not inclined with this kind of job, better bring it to a qualified technician. one more thing, i dont beleive that the house is related with this problem. otherwise all your equipment that are hooked up in it will do the same problem (on and off). i hope this help you! good luck!
