Change the 10 or so surface mounted bad filter caps in the Hyper module this set uses--the board is no longer available--it can be sent out for rebuild (not toshiba) but that is rather costly (200+)

Careful not to crack the signal board.

SOURCE: toshiba tp48d50 has vertical red wavy lines on

These Toshiba TVs are well known for convergence problems. When you put the convergence test pattern on the screen, does it appear normal? If there are curves in the crosshair lines and colors flairing from them, you have just such a failure. The convergence output ICs will have to be replaced. You'll spend $300-$450 to have this fixed.

Toshiba Model 51h84


The wavy when cold is a issue with a board in the set--Hyper board--the warmup until it begins to work will gradually get longer and longer.

The blue: look at set on a unused video input--if see faint curved blue lines with some blue visable on the screen the blue screen control needs to be adjusted just slightly down until the blue and curved lines are not seen.

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.

I have vertical lines on my screen. They appear to


This a common problem in many of the Toshiba sets----set has a "HYPER" circuit board that processes all the signal for the set--surface mounted caps all start to dry out--always starts out where it will have the problem and then when on for a while it gets better and goes away--eventually when enough of the caps are gone--it never gets better.

Board is now only available by removing it and sending it out for rebuild/repair---company doining this is Pts electronics--part number is:

23148103Cost is about 180 dollars plus shipping and this may mean considering the labor to get the board out that the set is not worth repairing.


Sorry to give you bad news but I am certain this is what your trouble is.

I do this here for free so if this information helped you to decide what to do--take a minute and give me a vote here.

Toshiba 50H82 has wavy lines in screen for about


this is a very common problem in a lot of Toshiba sets of this type----bad caps(filter capacitors) on the "Hyper" board---it processes all signals in the set---it will start out where it clears up after warmup and as time goes by it will take longer and longer to clear up----the board is no longer available and the only way to repair is remove the one in the set and send it out for rebuild---most of the time this costs 3-4 hundred parts and labor(not worth doing)

Toshiba 57H81 picture bounces. Can't tell if horiz. or vertical.


Unstable picture, wavy, jittery, and loss of sync are a symptom of bad capacitors in the hyper module. The problem is worse when the set is cold, but when warm the sympton gets less or goes away. In the latter stages the problem never gets better even after the set has been on for hours. There are about 6 surface mounted caps (10mf/16) inside the shielded Hyper module. The module is vertically mounted behind the jack panel and can be unplugged from its socket after unsoldering the 4 anchor tabs on the bottom side of the PCB. This type of repair should be made by a qualified technician do to the complexity of chassis removal and expert soldering skills.

Wavy picture on all sources


This is a somewhat common problem having to do with the hyper module, Toshiba p/n#23148024 There are a gouping of 16v/10uf caps in the hyper board that fail causing the distoritions you're describing here. At first, as the module begins to go bad the distoritions are present and usuallly go away or fade significantly as the set warms up - - this gets worse until the distoritions don't go away at all... From what you're saying you're at stage three already. :) You have a few of options: (1) local repair shop pull the board and replace the caps or module; (2) Pull the module yourself and repair or send it in for board level repair; or (3) pull the hyper baord, order a new one and put it in yourself. For 2 or 3 you'll be better off having the service manual and if you need it just email me privately and I'll send it. Make sure in your request to tell me the model number and reference something of this repair so I have a clue of what you need. BTW the hyper board is on the left side of the unit mounted vertical on the signal board inside a metal can. Good Luck Bill

Distorting


if it is wavy lines across the top it is probably the scan converter/ hyper bd they are becoming hard to find/expensive you can repair them but it requires many surface mounted capacitors and requires some VERY skilled soldering.
