Question about Televison & Video

2 Answers

I have a older rear projection Toshiba TV TP-61H60. I want to remove the chassis to change the convergence ICs (based on advice from this website). I have everything unplugged from the main chassis and it is ready to come out except for the focus HV lead. Can this lead be unplugged from the supply transformer like the main HV leads? It does not appear so and I don't want to create work for myself by damaging it. If not how can I disconnect it to get the chassis out and up on a work bench?

    Thanks Alpug, but I want to make sure i understand you. I pull back the rubber protector, exposing the entry point for the lead. Then I use a small jewelry screwdriver and insert it between the red lead and the housing and push down to release the lead?

    Thanks Eagle338, but it's not the main HV leads to the CRTs. It's the focus lead. I have a copy of the service manual. While the HV leads are removable from the voltage divider and fly-back by simply pulling out of the socket, the focus lead does not appear to be removable. Another expert (alpug) is saying that the focus lead can be removed by using a jewelry screwdriver to release a lock inside the flyback but I don't see where to do this. Can you help?

  • Douglas Mader Jan 05, 2011

    Eagle338 - no that's not the same flyback. Here's a picture of my chassis with the flyback on the right and the voltage divider (with the CRT HV leads removed) on the left. The lead I am speaking of is the small one in the right foreground

    Still confused. Here's a picture of my chassis with the flyback on the right and the voltage divider on the left (missing the CRT leads). the one on the lower right is the one I need to remove


  • Douglas Mader Jan 05, 2011

    Thanks. yes that looks like the right lead. So does it just pull out of the housing of the flyback or is there some other trick to remove it?

  • Douglas Mader Jan 05, 2011

    It looks to be too short however. In my set it goes in one run from the flyback all the eay to the focus adjustment potentiometer board - about 2 to 3 feet

  • Douglas Mader Jan 05, 2011

    thanks but I guess I just don't understand exactly how to release the lock

The HV leads(If you mean the one that come from the flyback) cannot be removed from the transfomer itself, but you can disconnect them from the CRTs. All you need to do is to squeeze and pull them from the anode cap. Be careful not to touch anywhere near the anode cap. The extreme high voltage can cause grievous bodily harm/ death if not handled carefully. It will be a good idea to discharge the voltages CRT before you begin.
Also read the disassembly instructions from this service manual, that I have uploaded for you.

    You should pry it out. I do agree partly with what A-plug said. You should release the lock holding the wire while slowly prying out the wire. It should not be too hard.

  • eagle338
    eagle338 Jan 05, 2011

    The lock is released by pressing down on the transformer and pulling out the wire. You should keep twisting and pulling. Give it shot, you won't understand what I am saying till you start pulling out the wire.

Yes that lead is detachable from the ply back transformer to do it just slide out the rubber protector of the contacts of the lead and the transformer next push down the lead use a small jewelry screw (precision screw) with flat head push down the lock **** from inside the transformer.after pushing the lock inside you can pull out the lead out of the contacts. To return the the lead just push in the lead and it will automatically lock returned the rubber protector...good luck!

    For a clear explanation:
    Slide out the rubber protector.
    Point the precision screw to the lock that holds the red lead. Exert some force to press and hold down the lock while carefully pulling out the lead.

Good morning, I am in the moving business and have a customer that wants me to move their large TV Mitsubishi medallion tv. She thinks is comes apart in two peices for easy moving and I need instructions...


If the model is a WS-65809 that sey doesnt come apart. Actually very few rear projection TVs can be seperated Some RCA TVs can be disassembled to several pieces. Also I would let customer know that because a CRT TV has three CRTs that are aligned to each other , Moving the TV will cause the convergence to be adjusted. Based on model it can be just pressing the auto convergence option with the remote, But older rear projection TVs (2003 and older) have been known to blow ICs after a move when trying to reset the convergence. The ICs weaken over age and they can blow anytime the convergence adjustment feature is used, so its always a good thing to let someone know that even if very careful when being moved there set may develop convergence issues after a move because its a 3 CRT rear projection TV

My Toshiba 53H71 rear projection TV's picture looks like double vision with a heavy tint outline how can I fix this???


Hi,
Double vision/ picture problem occurs due to failure of convergence output ICs in rear projection tv and it is common problem of projection tvs.
Please replace convergence output ICs in tv to solve the issue, there is convergence repair kit available for $70 on This Site that has required parts/ ICs, instructions about how to replace ICs etc for a handy person.
Hope these info will help.
Thanks.

I purchased the convergence chips for Samsung PCL5415RX/XAA TV. Do I need to remove the entire sub deflection board to R&R them?


Yes, however I would be surprised if changing the two Ics will repair the set, as that chassis should always have the sub-deflection board replaced since most of the resistors will be stressed. Thats why samsung changed the later chassis's by removing the convergence circuits from the deflection board as its almost 98% certain that the deflection board will need replacement when the ICs fail with those chassis designs unless every component in the convergence circuit is replaced which will cost more than the deflection boards do. But you may get lucky but if the ICs dont cure the problem you will need a new deflection board

Toshiba Rear Projection Tv 40WH08B


If the convergence on one or more color does not align using the convergence setup procedure, that means that one or more convergence ICs must be replaced, that is the reason why you get bad picture.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.

Here there is an example of the repair needed: Fixing Convergence problems in RPTV's
