Question about Panasonic PT-56HX41 56" Rear Projection Television

2 Answers

No picture or sound on Toshiba 53HX71 Rear Projection TV

The red color was out of wack, so I replaced the convergence IC's. I put everything back together and plugged it in. All I get is a click on the main power board. The power light on the front of the TV is on and is solid, but no picture or sound.

Good Day,
The TV has a convergence problem; the IC’s for that circuit will need to be replaced. The cost for this repair runs around $450.00 or more.

Replace the defective Convergence Output IC Part Number
23905094 (STK392-110) using the revised “T” version IC Part Number
23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version. Inspect the Convergence Output IC’s for the “T” type version as
shown in Figure 2. Replace the Convergence Output IC’s using the “T”
type version Part Number 23135090 (STK392-110T).

Thanks for choosing FixYA, Big Irish

Fuzzy picture and dark picture and color seperation when hot.


The colors seperating is a convergence problem, as far as being dim this may be related but the TV likely needs service adjustments.

convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!
