Toshiba tz50v51 relay clicks on when pulled in but 5 volts are missing from emmpom


check for a short to ground on that line if you have not, the most common issue is convergence which can cause the set not to come on also, look at all the pico fuses in the power supply--two go to the convergence chips, if you get desperate and the fuses are ok unsolder both chips (stk-392-110) and see if set powers up ----if it does and the fuses are good both chips and one of the resistors around them is what is causing the problem.

Convergence problems with the Toshiba TE50T11. Have tried to fix by remote and the colors will not align as they should. Left side of screen has blurriness, almost a 3d effect with alot of greenish tones....


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 over.

I have a Toshiba rear projection TV model # 50H71 for about a month the tv would randomly pop off (lose sound and picture) for about 45 seconds and then come back on now th picture is reduced in size by...


Good Day,
The TV has a convergence problem; the IC’s for that circuit will need to be replaced. The cost for this repair runs around $450.00 or more.

Replace the defective Convergence Output IC Part Number
23905094 (STK392-110) using the revised “T” version IC Part Number
23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version. Inspect the Convergence Output IC’s for the “T” type version as
shown in Figure 2. Replace the Convergence Output IC’s using the “T”
type version Part Number 23135090 (STK392-110T).

Thanks for choosing FixYA, Big Irish

I have a toshiba tz50v51 projection tv. the red power light is on


It could either be due to the convergence Circuits ( If the Power Indicator Blinks) or the power deflection board if it doesnt blink. I have a source for parts if you would like the link.
