Capacitors for Toshiba Hyper box

Mfr Number: 16V/10UF/MINI/SM Capacitor surface mount 5mm

I found this at your recommended part site. Will this work? to replace the old capacitors? Please let me know. These little bastards look hard to solder!

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 a Maxent 42 inch plasma.When you turn it on, it flickers for 5 minutes then comes on.recently the flickering continues non stop and now is almost unwatchable.Any idea what I can do to fix this? I...


What is the Product Name or Model number of your Maxent 42" Plasma TV? If it is a MX-42X3, Model # P420542HM8, I think I can help you. I have encountered this exact same problem with 2 Maxent MX-42X3 Plasma TV's. I found that C766, a 220uF, 16V surface-mount electrolytic capacitor on the main board is bad. This capacitor is located just to the left of the green multi-fin processor heat sink. This capacitor will test good using capacitor meter or an ESR meter, but if you spray it with Freeze-It with the power on, you will find out that this is the problem! To get it out, I found I had to remove the little 10uF 16V surface-mount capacitor just to the left of it. I then replaced these 2 capacitors with regular (radial), high-temperature, low-ESR capacitors. I cut the leads short, and bent the ends out just a little bit so you can solder them back onto the surface-mount pads. You can get these parts from Digi-Key Corp. I used Digi-Key part # P12383-ND ($0.32) for the 220uF capacitor, and P11212-ND ($0.30) for the 10uF capacitor. Both of these capacitors are rated for 25V and high temperature, so they won't go bad again. You can purchase surface mount capacitors there too, but I find them very difficult to solder back into those locations due to the tight placement of other capacitors in that area. If you're not an expert in soldering, I suggest you take the main board to a qualified electronic technician, and let him do it. But you better put the board in an anti-static bag before you take it anywhere! Hope this helps!

Tv flickers when first turned on. This can last for several seconds to about a minute.

You could have a bad color wheel or there is a Factory Service Bulletin from Toshiba that says: Remove the MVUP14 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.) You should call a good TV Tech to do this repair.

Toshibia Hyperboard Problem


Get 10uf/16v radial lead 105 deg caps. Cut the leads short so they fit under the shield and give them a bend like the letter L when you solder them on the pads. These caps are easier to use than the original surface mounts and much better. Be very careful removing the old caps as not to lift the pads to which they are soldered. I will caution you that this job requires expert soldering skills and a good soldering tool with a fine tip. This is not a job for a novice. I know plenty of pros that botched hyper modules. Take note to observe polarity of the cap when installing. I don't know the part numbers off hand but you can Google "Toshiba hyper module kit" and find a list. I use an ESR meter and test for the bad caps. You will use about 7 or 8 so it is cheaper to order a pack of ten.

Dougers, I am next door, in Alberta. I have fixed my hyperboard by replacing the surface mount caps myself in my workshop for a fraction of the cost of a replacement board.
See my other thread for more information.
