Toshiba 50HX81 50" Rear Projection Television Questions & Answers
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.
Blurry at first then when it warms up the distortion goes away
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.
There was a power outage in the building and now
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.
I HAVE 2000 TOSHIBA
U have tools lilke a soldering iron,solder,desoldering pump or soldering wick?U know how to do basic soldering?Try website like Tvrepairworld.com to buy a capacitors kit,to fix the DM power supply board,will fix this problems.
Toshiba 50HX81 TV looks kind of old school 3D with
No,not the bulb problems.Tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures look like.The Toshiba tv have a "HYPER BOARD"known as a convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts on the convergence board,must be replaced to solved the tv convergence pictures problems.U have tools like a soldering iron,desoldering pump or desoldering braids,solders?Can u do basic soldering?Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop,will cost u $300-350 for parts and labors.
When I turn the TV
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!
Toshiba 50HX81 only showing black and white
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.
