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!

I have a rca model led65g55r120q tv flickers and no sound


Check all cables for loose connection, try another input for picture (DVD, BLu-Ray, etc). If none of the other inputs work then it's a panel problem (display) If one or more of the others work then it's a problem with either the tuner or the signal.
