When switched on colours fine after short period colours seperate causing a 3d type effect


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

Powers off intermitantly


Good Day;

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB. 2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. OR your TV has "COOLANT" (ethylene glycol) on the circuit boards. This fluid comes from the CRT's (picture tube) this fluid is used to keep the CRT's cool, such the name. This fluid from the CRT's leak when TV is on for long periods of time, the chamber expands and the seals leak.

One can remove this fluid by using "acetone" & small brush. The fluid is hard to see, use bright light, they spots can be smaller then a DIME. Also, the fluid can corrode the parts and traces on the boards. To protect the TV in future place heavy plastic or thick cardboard over affective area, make sure TV has proper air flow around TV. Good Luck, big IRISH.

Repair to be rectified


Hi there!
My guess is that you have a frame collapse. This is run by a circuit in the TV that opens the screen from top to bottom. If it was a second hand purchase then this could be due to general failure. I would return it to the seller for repairs, Good Luck, JUS004

Turn of sometime


I would check out your power supply and shut down circuitry as thats what yourset is doing when it shuts down its ging into the protection shut down. You can get the power supply and shutdown troubleshooting quide for your set at the following link for 10.99 and if you request that they email it they will. You just have to return after you order and click on the contact link to request they email instead of mail your manual. Heres the link.

Toshiba 42wt29b. screen keeps turning blue


MMMM Hard call here. The fact that it does try to come on blue maybe an indication that the power supply regulator circuit is good. It could also be a shorted blue tube and when it comes on its overloading the screen drive and the set goes into overload protection shutdown. The real way to see Would be to pull off the blue crt socket as well as the Hi Voltage lead on the crt and see if the set comes on without blue. If it does Your gonna need a pict tube. If it dosent then troubleshooting along the switched power supplys would be neccassary.. BUT I advise you THAT IF YOU HAVE NO EXPERIENCE TROUBLESHOOTING TV SETS PLEASE SEEK A PRO TO ASSIST YOU AS THERES VERY HIGH VOLTAGE INSIDE THESE SETS EVEN IF THEY ARE UNPLUGGED. GOOD LUCK
