20 Most Recent Toshiba TP50H50 50" Rear Projection Television Questions & Answers


Likely has bad convergence chips and one or more open fuses on SMPS board.

Toshiba TP50H50... | Answered on May 08, 2014


The flashing power light on those Toshibas is usually caused by capacitors on the power board having failed solder connections. I have fixed them before by removing the power board and resoldering the capacitors. If you have experience with soldering and electronics it is an easy repair. Most shops will recommend replacing the entire board since their labor to repair it would probably cost more. Toshiba put out a service bulletin on this issue which a good technician should be aware of. (If memory serves the capacitors are C109 and C110.  Since your TV still turns on you probably haven't blown fuse F860 which often blows when these capacitors act up.)
If you would like further help with this please post a comment back here.

you can remove the screen but there is a easier way, from rear with cover removed use a swiffer cleaner to get at the webs etc. Gently.

The Toshiba part number is: 23837513, but htis part is listed as no longer available. All you can do at this point is to try and call different Toshiba parts distributors or service shops to see if anyone still has one around.

If toshiba projection go to main menu and engage convergence to look--should offer some points on screen where you can try to adjust.

If badly skewed or will not adjust (based on model number posted here) both the stk-392-110 chips will have to be replaced and the set adjusted.

This can be a do it yourself repair if you have some skill--soldering is involved as both chips have 18 pins each.

Let me know what you find and if you have questions.

Set should be worth fixing ,The most common cause of this is Bad STK ICs . They are Big Black ICs and will have the part number on them,example STK392-110

Repair or replace the power supply

Toshiba TP50H50... | Answered on Jun 14, 2011


Hello,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
This will help.

The blinking LED is the Fault code for your set. Its shutting itself down into protection mode to stop from further damaging itself. Kinda like a fail safety. My fix instruction differ for rear projection than that of PDP or LCD but its the same. Just a dif set up inside the set.

hi

blakedidit,

Thanks in advance for choosing Fixya for assistance!

I would like to have a clarification request before I present my solutions

to your problem.


does the fuse comes from a circuit like these?

As I look for more possible solution to your problem, would it be

possible to to post part number of the component within the board


or send an image where I can encircle the possible causes.


I need also to know if, it the TV do still have a sound even without

the fuse? or a raster perhaps , or is the Flyback, oscillating?




Regards,
