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.)
TOSHIBA AMERICA GOISJSUIVIIER PRODUCTS, L.L.C.


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.

Shakey Screen


That problem is caused by defective capacitors on the Hyper Board location UZ01 stamped MVPU14. You will need to have a technican remove the board and replace all the 10 uF @ 16 Volt SMD caps p/n 24619040N found on that board. The Hyper board is no longer available as a part.
