20 Most Recent Toshiba 50HX81 50" Rear Projection Television Questions & Answers

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.

Most of the Toshiba sets of this age had problems with a board inside that gives lines/noise left to right for several minutes and then clears up--as time goes on the warmup takes longer and longer---bad Hyper board with about 10 tiny surface mounted filter caps that dry out.

Part is not available and two options--either have a shop repair it or try it yourself---takes above average skill to remove board and replace all ten caps.

Shops will if they will attempt this usually get over 200 for the repair.

Its called a micro-switch and they are fairly generic--look for a parts set similar to yours. If you need the actual plastic button array try Toshiba who might still have it.

You will most likely need a tech to repair the power supply.

You could contact a BIG name repair group, But if you can find a guy like me,

you could get it repaired for the less than $10 costing part it needs and a very fair
labor charge. Us unemployed guys give good deals.

I would do it if you were close.
Toshiba is a notoriously good fix.
Very worth it.
You need a tech.

You need the Red Green and Blue lights realigned in the rear. Usually costs 200-500 and not worth it on such and old TV. Go to Wal-Mart or online and buy a new Plasma/LCD!

Sounds like you have a weakening horizontal capacitor in the power supply. I would certainly visit your local TV tech and have them repair this. It is neccessary to service now before repairs are to expensive. H ave them check all capacitors and resolder any and all bad grounds. The ones in particular include any ICs mounted on heat sinks and your power resistors and horizontal transformers. This should cover most of it. Take this note to them. They will know what you are asking. Thanks for asking!

I bet it's a DLP TV correct?
This symptom would indicate that the color wheel has flown apart. Which results in a monochrome only image.
Color wheels are expensive and need to be replaced by a qualified service person.
