Toshiba model 57H81

When TV is first turned on there appears to be an instability in the horozonal, after 20 minutes or so(time keeps grtting longer), it settles down and picture is normal. If we leave the TV on, problem never appears. If you turn it off, even for 5 minutes, the instability appears and it takes 20 minutes to settle down. TV is 4 years old. Please help? What PC board or module will I have to replace? Thanks, Ed Wilson

    Hyper PCB unavailable,part # 23186198. Does anyone know the size and voltage rating of the capacitors on this board that need to be replaced to eliminate the horzonal tearing? Are they electrolytic? Any help out there? Thanks, Ed Wilson

    I actually have a Toshiba 53HX71 with a vertical instability issue. The problem has gradually gotten worse over the past couple of weeks. Both the OSD and picture bounce some vertically when the problem appears. The problem occurs quite frequency but sometime the picture stabilizes for sometime before the vertical jittering starts again. I appreciate your input.

    We just recieved this TV for free and the image scrolls horizontally for a while then when it calms down its still a bit shakey and looks like its being tugged to the left and doesnt look as clear as it should. Is it a focus problem or does something need to be replaced? How much would it cost to fix it?

I have a Toshiba Modle 57h81. When you turn the TV on it automaticly goes to shut down mode. I've already check the fuses which are all okay. As well as changed out the convergence ic's. The problem continues to remain. Can anyone help me?

If you have zagged lines there are 10 small surface mounted capacitors you will need to change on the HYper Board. This is not an easy repair so alot of folks simply replace the hyper board. You will need a service manual to take this set apart and to get the proper part number. If you have no TV repair experience or do not know how to solder, as the hyper board has sheild arounfd it, you should play it safe and call out a pro to assist you in this repair. Good Luck

My toshiba 57h81 starts with waves and after 4-5 minutes it is ok. What could be the fault and how much could it cost me?

This model uses a "HYPER" BOARD to process all signal from all inputs.

These sets have a history of tiny surface mounted capacitors on that board failing with age---they dry out inside.

Usually it will clear up as the caps get hot but over time it will take longer and longer to clear up.

The board is no longer available from Toshiba and the only way to fix is remove the board and send it out for rebuild---last one I did cost over 200 for the rebuild.

I have had a few on this site with this problem who were able to do the repair themselves, it involves getting the board out and real skill at soldering.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

Picture is wavy then fine, happens every two minutes

This model like several others had problems with what is called a Hyper board inside which processes all signal inside the set.

From a Toshiba service bulletin:

No: PJTV200503 2 Pages Ref: WU032505
Product: Projection TV Date: 3/25/05
Models: 42H81,43HX71, 43H71, 50HX81, 50H71, 50H81, 53HX71, 53H71, 57HX81, 57H81, 61H71, 65HX81 AND 65H81
Product Safety Precautions:
Product Safety Precautions are described in the Toshiba service manual(s) for models covered in this bulletin. All safety precautions and checks shall be complied with before returning the equipment to the customer. Servicers who defeat safety features or fail to perform safety checks may-be liable for any resulting damages and may expose themselves and others to possible injury.
Application: The information contained in this bulletin applies only if you encounter the symptom(s) listed below.
Subject: MVPU13 Hyper Module Repair (23786198 / 23148017X)
Symptom: Multiple Symptoms may be experienced depending on which capacitor is faulty. The primary symptoms are jagged, digitized or pie crusting of the picture. The set may also be described with a poor sync condition.
Corrective Action: Remove the MVUP13 Hyper Module from the TV chassis, remove the top shield and replace the 10uf, 16v capacitors using Part Number 24619040 as shown in Figure 1. It's recommended that all of the capacitors identified in Figure 1 be replaced. (Note: These capacitors are low impedance surface mounted aluminum electrolytic capacitors. Care should be taken to avoid damaging the PCB while replacing these capacitors.)

There are several surface mounted capacitors that dry out with age and usually the problem starts out when first turned on and then eventually after on a long enough time the set works--the time will get longer as the problem gets worse.

The board is no longer available and only two options here: locate and replace all the selected caps which is not a do it yourself job or remove the board and send it out for rebuild.

Let me know if you need more info as I have seen dozens of these sets with this kind of problem.

After about 15 to 20 minutes lines start appearing on the screen

Check for cold solder joints around and including the Convergence IC's.

Red power light continuously blinking. no picture no sound.

It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service
