Toshiba vertical collapse t.v. picture tube type A68LUW696X01

Hi,
this t.v. had vertical collapse and returned to normal after turning t.v. off for a few weeks then reverted to v. collapse permanently. Should I attempt to resolder the verticle board joints and if so how do I identify this part inside the t.v.?
Any other suggestions? thanks,
the t.v is 6 yrs old (03-23-02) a 27 inch flat tube t.v. model #27AF42 chassis # TAC 202.

thanks,
Mario

Hello Podman6,

Does the fault come on and off when you tap the case/cabinet of the TV? If so, then this is a dry joint/cold solder somewhere on the mainboard.
If you are are not qualified, do not take the cover off.
Look for a "largish" aluminium heatsink, located probably near the middle of the PCB. (It may be on the right hand side.)
With the cover off & an image showing on the TV, tap the heatsink with the "handle" of a screwdriver. Search for the most sensitive heatsink. Disconnect the power look closely at the other side of the most sensitive heatsink & you will probably find a "dry jointed" I.C.

If your set has an IC.501, look for a small capacitor near this IC./it will be 1 uf/50v or 2.2 uf/50v. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic (not same model):

Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you.

REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.


If you are unsure, PLEASE CALL A QUALIFIED REPAIRMAN.

Hope that helps, and thank you for using FixYa!

Vertical amplifier?


Your right, it's called "Vertical Collapse", it's caused by the vertical output IC, which may be dry jointed or failed, try applying new solder to it if you can, if that does not work, you will need to replace the IC. A simple test to test for dry joints (where the solder is cracking and not causing proper connection from the pins to the board). If you give the unit a bit of a hit you may see the picture return to normal... don't do this too often as you can make more damage.

Redness in picture


The Convergence amps in this TV set will need to be replaced. This is a typical repair that has to be repaired in almost every tube type projection TV set ever made. Not really a hard job, but a knowledge of printed circuit boards and soldering will be needed and if you do not have the soldering and unsoldering skills, leave the repair to a pro. A repair such as this will run anywhere from 225 up yp 400 bucks. Good Luck and let us know how this repair worked out for you.

Toshiba TV with only a horizontal picture?


You could have a simple loose connection on the vertical output IC . Sometimes you can tap the board and the picture will fill out . Or the IC could have failed . It will also take out the resistor that supplys the voltage to the vertical IC . If you take it apart to work on be careful as you can be shocked if you don't know what your doing . Most repair shops charge $50 to $80 to repair . Good luck
